Lady Macbeth Has Been Described as the ‘Fourth Witch’

Woman Macbeth is a treacherous and complex character. Over the span of the novel, she controls her significant other, Macbeth, and prods him to submit his first homicide with the end goal for him to eventually accomplish what she accepts he merits. Woman Macbeth is appeared to the crowd as a faithful spouse who needs the best for his significant other, and yet, she is depicted as a malevolent character from the earliest starting point of the play. The line between an insidious individual, and a conspiring witch, is fine to such an extent that Lady Macbeth could without much of a stretch be either. The way that the three Weird Sisters’ forecasts would not have gotten valid without the incomparable impact of Lady Macbeth incites the idea that, maybe Lady Macbeth is in excess of an enemy of mother and a conniver, maybe she is a witch. This chance would likewise change the idea of the witches from the future-soothsayers they are depicted as, to simply influencers of a series of occasions that they plan. So as to separate or partner Lady Macbeth from or to the unusual sisters, the similitudes and contrasts of Lady Macbeth and the witches must be investigated. Right off the bat, Lady Macbeth and the witches both approach to underhanded powers now and again of need, for example, when Lady Macbeth cries â€Å"Come, you spirits/That tend on mortal musings, unsex me here,†(I, 5, 39-40) to dispose of her ladylike characteristics with the end goal for her to inevitably be fruitful in satisfying the witches plan by prodding Macbeth to slaughter Duncan. This conjuring implies a connection between Lady Macbeth and the extraordinary, or black magic, which is used by her and the witches. Not long after the conjuring, she questions Macbeth’s masculinity by revealing to him that â€Å"When you durst do it, at that point you were a man/And to be more than what you were, you would be quite a lot more the man. †(I, 7, 49-51). As Lady Macbeth disposed of her womanish qualities and comprehends the genuine idea of a man, she started to impart a specific sex vagueness to the witches, Banquo watches the genderless appearance in the witches when he announces â€Å"You ought to be ladies/And yet your facial hair deny me to decipher/That you are so. (I, 3, 46-48). In the event that Lady Macbeth had effectively associated with the underhanded powers in her conjuring scene, at that point both the witches and Lady Macbeth show a gender ambiguous character, in spite of the fact that Lady Macbeth just has manly mental qualities, while the witches have a manly physical appearance just as mental character. Another regular characteristic between Lady Macbeth and witches is that both are enemies of moms. The fantasies of witches through history are viewed as enemies of moms, and Lady Macbeth uncovers this detestable trademark rom inside herself, and the reality of a past maternal relationship when she says â€Å"I have given suck †I would †have culled my areola from his boneless gums,/And ran the minds out! †(I, 7, 54-58). This stunning articulation shows Lady Macbeths underhanded considerations, which no mother could have for her youngster, thusly making her an enemy of mother, which would likely have been connected to black magic by the first crowds in Shakespeare’s day, if not by today’s crowds. Equal expression with Lady Macbeth and the Weird Sisters are likewise obvious in the play. The witches allude to â€Å"killing swine† (I, 3, 2) right off the bat in the play, and Lady Macbeth unwittingly echoes this when she alludes to the two chamberlains as in a â€Å"swinish sleep,† (I, 7, 67). The chamberlains are relinquished by Macbeth, to stay away from any shortcoming in their arrangement of the homicide of Duncan. The penance of pig has been known as a typical demonstration of legendary witches since before Shakespeare’s day, and once more, joins Lady Macbeth to black magic. The utilization of The previously mentioned term (â€Å"swinish sleep†) relating with the penance of the men being portrayed accordingly, would be an insight to the crowd of Lady Macbeth’s witch-like character, and would have, by and by, have associated Lady Macbeth to black magic for the crowd of Shakespeare’s day. In contrast to the witches, Lady Macbeth gives indications of helplessness, and becomes wracked with blame. This is obvious in her sleepwalking scene, when she says â€Å"Out condemned spot! Out, I state! (VI, 1, 31) She, by then, was spooky by seeing blood on her hands, and was persuaded the blood was still there, giving indications of frenzy as she turns out to be intellectually unhinged. Woman Macbeth’s memory of Macbeth’s words after Duncan was killed likewise spooky and putrefied inside her as demonstrated when she begins to reverberate Macbeth’s proclamations and fears, when she said â€Å"To bed, to bed: there’s th umping at the entryway! †(VI, 1, 59) When Lady Macbeth is sleepwalking and envisions that she is in heck, as appeared by her announcement â€Å"Hell is murky,† (VI, 1, 32) she doesn't show up in front of an audience once more, and passes on offstage. The two in all likelihood situations for her demise would be self destruction, or a demonstration including the specialist as well as the woman of honor, as they were the main individuals that saw reality with regards to the homicides. On the off chance that self destruction was the reason for Lady Macbeth’s passing, as is likely, a considerably more profound degree of blame is appeared and this enthusiastic injury felt by Lady Macbeth isn't felt by the witches. These indications of shortcoming are in opposition to the association she had with the detestable spirits in her inspiration scene, and in opposition to the conduct of he witches, as they don't feel, or even show any blame or compassion. Regardless of not having a manly appearance and giving indications of blame and shortcoming, Lady Macbeth has been shrewdly depicted as the ‘fourth witch’ by Shakespeare. I accept this is thus, on the grounds that at the time this play was composed, connections, for exampl e, the ‘swine’ portrayal of the specialists and the approaching shrewdness spirits performed by Lady Macbeth would have been obtrusive equals and connections to black magic for the crowd in the Elizabethan time, however are maybe more once in a while comprehended by today’s crowds. This might be on the grounds that witches has been excused by present day society and their attributes are not as generally known creation those connections fairly obsolete. In spite of the fact that Lady Macbeth as the ‘fourth witch’ appears to be less conceivable as an idea today, we should not take a gander at the play as two dimensional, as today is perused, yet rather become familiar with the perspectives on the individuals of when Shakespeare’s plays were composed, all things considered, Shakespeare expounded on what he knew, and Macbeth was composed 400 and three to 400 and seven years back.

It monitors the following memory address of the guidance that will be executed once the execution of the present guidance is finished. At the end of the day, it holds the location of the memory area of the following guidance when the present guidance is executed by the microchip. 5. What is a memory word? What's more, what does it contain? Inside capacity regions in the PC. The term memory distinguishes information stockpiling that comes as chips, and the word stockpiling is utilized for memory that exists on tapes or plates. Additionally, the term memory is typically utilized as shorthand for physical memory, which alludes to the real chips equipped for holding information. A few PCs additionally utilize virtual memory, which extends physical memory onto a hard circle. Each PC accompanies a specific measure of physical memory, for the most part alluded to as primary memory or RAM. You can consider primary memory as a variety of boxes, every one of which can hold a solitary byte of data. A PC that has 1 megabyte of memory, in this manner, can hold around 1 million bytes (or characters) of data. There are a few unique kinds of memory: RAM (arbitrary access memory): This is equivalent to principle memory. At the point when utilized without anyone else, the term RAM alludes to peruse and compose memory; that is, you can both compose information into RAM and read information from RAM. This is rather than ROM, which grants you just to understand information. Most RAM is unstable, which implies that it requires a consistent progression of power to keep up its substance. When the force is killed, whatever information was in RAM is lost. ROM (read-just memory): Computers quite often contain a modest quantity of read-just memory that holds guidelines for firing up the PC. In contrast to RAM, ROM can't be composed to. PROM (programmable read-just memory): A PROM is a memory chip on which you can store program. Be that as it may, when the PROM has been utilized, you can't clean it off and use it to store something different. Like ROMs, PROMs are non-unstable. 6. What is implied by interfere? Why it is valuable? A hinder is a sign from a gadget appended to a PC or from a program inside the PC that causes the principle program that works the PC (the working framework ) to stop and make sense of what to do straightaway. Practically all close to home (or bigger) PCs today are interfere driven that is, they start down the rundown of PC guidance s in one program (maybe an application, for example, a word processor) and continue running the directions until either (A) they cannot go any further or (B) an intrude on signal is detected. After the intrude on signal is detected, the PC either continues running the program it was running or starts running another program. 7. What are the two fundamental pieces of guidance cycle? What does each part do? The timespan during which one guidance is gotten from memory and executed when a PC is given a guidance in machine language. There are regularly four phases of a guidance cycle that the CPU does: Fetch the guidance from memory. This progression carries the guidance into the guidance register, a circuit that holds the guidance so it very well may be decoded and executed. Unravel the guidance. Peruse the powerful location from memory if the guidance has a circuitous location. Execute the guidance. . 8. What do MAR and MBR rely on? What are they utilized for? Blemish represent memory address register MDR represent memory information register MAR it holds the location of the presently tended to memory area MBR it holds the code read from the at present location memory area 9. What is the quickest and second quickest type of memory? Why there are numerous degrees of recollections (memory chain of importance)? CPUs broadly useful registers. The registers give the quickest access to information conceivable, and the second quickest type of memory is Cache. There are numerous degrees of memory chain of importance to have great expense and execution of the different spots we can store information and directions 10. Expect the reserve hit proportion is 85% and the entrance time for the store is 1 small scale second while the entrance time for the primary memory is 100micro second. What is the normal access time? Normal Memory Access time = Hit time + Miss Rate x Miss punishment (0. 85) (0. 1 Â µs) + (0. 05) (0. 1 Â µs + 1 Â µs) = 0. 085 + 0. 055 = 0. 14 Â µs 11. What is reserve substitution calculation? Notice a procedure that can be utilized for store substitution? A reserve substitution calculation is a nitty gritty rundown of guidelines that coordinates which things ought to be disposed of in a registering gadgets store of data. Instances of reserve calculations include: Least Frequently Used (LFU): This store calculation utilizes a counter to monitor how regularly a passage is gotten to. Least Recently Used (LRU): This store calculation keeps as of late utilized things close to the highest point of reserve. Versatile Replacement Cache (ARC): Developed at the IBM Almaden Research Center, this store calculation monitors both LFU and LRU 12. What is a procedure? Rundown 4 of procedure components and clarify them? Is an occasion of a PC program that is being executed?

What does the dispatcher do? When accomplishes it work? The dispatcher segment is answerable for directing control to the most elevated need unit of work that is prepared to execute. The dispatcher forms work in the accompanying request: 1. Uncommon ways out These are ways out to schedules that have a high need in view of explicit conditions in the framework. For instance, on the off chance that one processor in a multiprocessing framework fizzles, interchange CPU recuperation is conjured by methods for an extraordinary exit to recoup work that was being executed on the bombing processor. 2. SRBs that have a worldwide need 3. Prepared location spaces arranged by need A location space is prepared to execute on the off chance that it is traded in and not sitting tight for some occasion to finish. A location spaces need is controlled by the dispatching need determined by the client or the establishment. Subsequent to choosing the most elevated need address space, z/OS (through the dispatcher) first dispatches SRBs with a neighborhood need that is booked for that address space and afterward TCBs in that address space. 14. What is a blocked procedure? A blocking procedure is typically hanging tight for an occasion, for example, a semaphore being discharged or a message showing up in its message line. In performing various tasks frameworks, such procedures are relied upon to inform the scheduler with a framework call that it is to pause, so they can be expelled from the dynamic booking line until the occasion happens

Chemical Engineering Characterization HgS/CdS Core-Shell - 2475 Words

Chemical Engineering: Characterization of HgS/CdS Core-Shell Nanocomposite Using Photoacoustic (Research Proposal Sample) Content: Characterization of HgS/CdS Core-Shell Nanocomposite Using PhotoacousticName:Institution:AbstractNanocomposite materials provide a chance for better functionality as well as multifunctional properties compared to their single-component counterparts that are perceived as more limited. A good example of Nanocomposite material includes inorganic core cell structure where the core and the shell comprise of semiconductors. Besides, there is enhanced photoluminescence through the shell motif, enhanced stability against photochemical oxidation, improved processability amongst engineered band structures. Despite the current modifications and improvements made in the core shell structures, there are still gaps in the characterization of these samples. This study seeks to provide an efficient characterization technique for HdS/CdS core-shell Nanocomposite through Photoacoustic. Besides, these results will be compared with TEM, UV-vis and XRD results with an intent of shedding m ore light on the solar cell.KEYWORDS:HgS/CdS Core-Shell Nanocomposite, Photoacoustic, TEM, XRD, UV-vis, Photoluminescence IntroductionIn reference to Chaudhuri and Paria (2012), nanomaterials possess various dimensions on the nanometer scale in addition to depicting novel properties from their bulk materials. In this case, the synthesis, characterization as well as the application of nanoparticles provide the basic areas of nanotechnology. Over the past few years, nanoparticles have been in the spotlight as there is increased need to advance from microparticles to nanoparticles. This study will seek to provide a medium to characterize HgS/CdS core-shell Nanocomposite that is vital in enhancing immense changes in the chemical or physical properties of a material. Background: Core/Multishell Semiconductor NanoparticlesThere are several benefits associated with this class of nanoparticles. Chaudhuri and Paria (2012) state that multilayer semiconductor nanoparticles give higher quantum yield, improved optical properties, photoluminescence, easier detection of the emission spectra since they are shifted toward greater wavelength in the visible range. Besides, these particles also present improved electronic properties as well as better structural properties compared to unlayered CS particles. Wu, Bittner and Kern (2005) define this lattice mismatch as a situation where two materials with varying lattice constants are brought together through depositing one material on top of the other. Some of the advantages associated with lattice mismatch between the material making up the core and the shell are that the shell grows to significant thickness while conserving its luminescence properties. The rationale for this study follows the influx of interested parties in nanoparticles due to their enormous, exciting applications. In reference to Harrison et al. (2000) when a smaller band gap semiconductor material is embedded between the core and the outer shell of the materia l with a larger band, such particles are thus defined as QDQW (Quantum Dot Quantum Well). The selection of core and shell materials is carried out mainly considering the band gap and the lattice structure of the sample used to make the CSS semiconductor particles. In this study, the author will characterize HgS/cdS core-shell Nanocomposite, which is an example of the particles mentioned above. Chaudhuri and Paria (2012) state that the optical or photostability of the multilayered particle is comparable to that of HgS/CdS as a result of the further coating on CdS, which is a high band gap compound. In this case, the quantum yield also escalates. HgS is a low band gap compound, and when sandwiched with a high band gap compound such as CdS, the electrons are consequently confined within the HgS layer as well as forming a quantum well. Problem StatementNormally, the TEM micrographs fail to show the core as well as shell structure as a result of the similarity in the core and shell mate rials as well as the nanometer size. In this case, a better characterization technique is required to facilitate proper characterization of these Nanocomposite particles. As of the moment, it is not clear on how core and shell nanoparticles can be documented clearly and characterized adequately. In general, the research on synthesis and characterization of core and shell nanoparticles is in its infancy and as a result, focused studies are called for to ensure better formation methods and better techniques for characterization.HypothesisPhotoacoustic offers a better channel to characterize HgS/CdS core-shell Nanocomposite amongst other Core/Multishell semiconductor nanoparticles.Objectives To characterize HdS/CdS core-shell Nanocomposite To find out the most efficient method for HdS/CdS characterization between the four methods of sample analysis used in the study. To provide a vast background on Multishell semiconductor nanoparticles. To analyze previous research studies carried out on this topic in the literature review and point out gaps in current literature. To provide a glimpse of the four tools deployed in the methodology for analyzing the sample To examine the differences in the particle sizes as indicated by the various analytical methods used. Literature ReviewIn reference to Harrison et al. (2000), the resulting hybrid nanocrystals showed a considerable increase in the QE (Quantum Efficiency) over the CdS material. Semiconductors are defined as quantum dots that belong to a state of matter between the molecular material and that of the bulk. Their large surface to volume ration and the quantum confinement effect are behind the unique physical and chemical properties. The quantum confinement effect comes about when the particle size is less than the exciton dimensions. Also, there is the widening of the bandgap as well as a blueshift of the photoluminescence (PL). Besides, Kim et al. (2004) argue that Nanocomposite materials do provi de possibilities for enhanced functionality as well as multifunctional properties. The authors claim that in cases where semiconductors are made of the core and the shell, the core-shell motif allowed enhanced photoluminescence as well as enhanced stability against photochemical oxidation. Harrison et al. (2000) state that some of the variables affecting the Photoluminescence behavior, charge carrier dynamics, non-linear optical properties and phase transitions include particle size distribution, special properties, and the nanocrystals surface. There exist numerous recent achievements in the wet chemical synthesis of nanoparticles of higher quality as described by Harrison et al. (2000). Improved characterization of these particles has enabled their applications in optoelectronic and electrical devices. Besides, the authors note that precise monolayer control of the chemical growth process is enabled and can be exploited in the formation of core/shell structures. An example includ es HgS/CdS, which is more robust physically with better surface passivation. As a result, better quantum efficiencies (QEs) are achieved in such samples compared to the other basic organic capped particles. Harrison et al. (2000) reports that quantum dot quantum Wells (QDQW) are alternating multi-layer structures such as CdS/HgS/CdS. On the article presented by Kim et al. (2004), X-ray powder diffraction (XRD) determines the growth in Co nanocrystals (NCs) as the preparative method deployed here. The yielding XRD pattern contains extra diffraction peaks that are indexed to wurtzite CsSe. The extra broadness of the XRD reflections in the composite structure pattern is as a result of the small domain size characteristics of the polycrystalline CdSe shell. In reference to Kim et al. (2004), TEM is used in observing the core size and shape in Co in which decrease in blocking temperature is associated with the reduced interparticle magnetostatic interactions resulting from changes in enc apsulation matrix. The matrix changes from strictly organic surfactants to an inorganic CdSe layer. In reference to Chaudhuri and Paria (2012), the process of synthesizing nanoparticles is complex in that there are various techniques to produce different types of nanoparticles. Some of the techniques deployed include synthesis by chemical reaction, condensation from vapor as well as milling that is a solid-state process. Chaudhuri and Paria (2012) argue that the above techniques were used, pure nanoparticles, hybrid or coated nanoparticles with hydrophobic or hydrophilic materials were synthesized depending on the suitability of the applications. The core/shell nanoparticles are classified according to the multiple or single materials into simple and core/shell or composite nanoparticles. While simple nanoparticles are generated from a single material, composite and core/shell are made up of more than two materials. In the classification of these materials, they can be defined broad ly as comprising an inner material (core) and outer layer material (shell) such as inorganic/inorganic, organic/inorganic, inorganic/organic as well as organic/organic materials. Chaudhuri and Paria (2012) state that the choice of the shell material depends greatly on the expected use or application of the nanomaterial. The most common core/shell nanoparticles include the concentric spherical type in which the simple spherical core is coated completely with the shell of another material. Smith, Mohs and Nie (2009) argue that following their different novel properties, differently shaped core/shell nanoparticles have continues to attract immense research interest. In reference to Mbese and Ajibade (2014), CdS/HgS is an inorganic (semiconductor)/Inorganic (semiconductor) Core/Shell formed through precipitation. As per Chaudhuri and Paria (2012), some of the characteri...

Challenges in Services Marketing free essay sample

MARKETING CHALLENGES IN SERVICE MARKETING Managing, growing, and profiting with both product and service businesses are challenging tasks. But the challenges are different from one to the other. Listed below are some of the most common and difficult challenges of growing and managing consulting, professional, or technology service businesses that dont necessary apply to product businesses. 1. Clients cant see or touch services before they purchase them Clients cant see or touch services before they purchase them. This makes services difficult to conceptualize and evaluate from the client perspective, creating increased uncertainty and perception of risk. From the firms perspective, service intangibility can make services difficult to promote, control quality, and set price. 2. Services are often produced and consumed simultaneously Services are often produced and consumed simultaneously. This creates special challenges in service quality management that product companies do not even consider. Products are tested before they go out the door. We will write a custom essay sample on Challenges in Services Marketing or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page If a product has quality problems while in production, the company can fix them and customers are none the wiser. Service production happens with the customer present, creating a very different and challenging dynamic. 3. Trust is necessary Trust is necessary. Some level of trust in the service organization and its people must be established before clients will engage services. This is as important, sometimes more important, than the service offerings and their value proposition. 4. Competition is often not who you thinkCompetition is often not who you think. Competition for product companies are other product companies. Competition for service companies are often the clients themselves. Sure, sometimes you find yourself in a competitive shootout (some firms more than others), but often the client is asking should we engage this service at all and if so, should we just do it in-house. 5. Brand extends beyond marketing Brand extends beyond marketing. Brand in service businesses is about who you are as much as what you say about yourself.And internal brand management and communications can be equally as vital to marketing success as are external communications. 6. Proactive lead generation is difficult Proactive lead generation is difficult. Many service companies have tried, and failed, at using lead generation tactics that work wonders for product companies. Implemented correctly, traditional product techniques, such as direct marketing and selling, can work for services, but the special dynamics of how clients buy services must be carefully woven into your strategy. . Service deliverers often do the selling Service deliverers often do the selling. Many product companies have dedicated sales forces. For services, the selling is often split between sales, marketing, professional, and management staff. 8. Marketing and sales lose momentum Marketing and sales lose momentum. Most product companies have dedicated marketers and sellers. They market and sell continuously, regardless of the revenue levels they generate. In many services companies the marketers and sellers also must manage and deliver.This can often lead to the Services Revenue Rollercoaster-wide swings between revenue and work overflow, and revenue and work drought. 9. Passion is necessary, yet elusive Passion is necessary, yet elusive. The more passion, spirit, hustle, and desire your staff brings to the organization every day, the more revenue and success you will have. The correlation between staff passion and financial success is direct and measurable (as is the correlation between lack-of-passion and organizational failure). Yet institutionalizing passion, while necessary, is agonizingly elusive.

TolkienThe story begins with a small fellow by the name of Bilbo Baggins The Hobbit he lives is in his house and doing what hobbits do during the day.

Bilbo is cleaning his house and preparing for a meal when an old friend of his comes past his doorway and starts to chat with Bilbo about all his adventures he has been on. After a while of talking in Bilbos hobbit home he tricks poor Mr. Baggins into join a journey with Thirteen dwarves to revive their lost city that was over ran by Smuag, a mysterious dragon that was used for delivering messages from dwarves and elves.

After washing the dishes he sat down to have a smoke with his pipe and was disturbed again, but it was Gandalf telling him that they are staying at the town inn. As he rushed to meet them he made it theyre just in time and they started discussing the plan (for Bilbo was their burglar and his job was to find the entrance to the secret door on the mountain where Smuag lay asleep) after the plan was discussed they set out on their journey to revive the lost city. They all were to small to use horses so they used ponies, except for Gandalf who was human size. The first camp they made was near a river outside of town. When they woke up they all had a well breakfast, and got an early start on their journey and was pretty much a safe ride until it started to rain and they needed to look for a place to camp when Bilbo heard some feet and they sent him to invest- agate on what was the noise, and there he found trolls and tried to pick- pocket the troll, but as soon as he put his little hand in the pocket, the troll saw him and picked up Bilbo by his legs and dropped him wondering if he is tasty enough to eat. Just when bilbo was about to be eaten by a troll, the troll knew there was more of his type around in the forest so the trolls made a trap and they hid from them. When the dwarves got worried and angry when Bilbo didnt come back and he was not answering the calls of the dwarves they followed his hobbit footprints and saw the fire. They got too interested with the fire and didnt think about caution, they where easily captured by the trolls except Thorin Okensheild, he put up a fight and slashed the one trolls eye. But Bilbo wasnt captured he was just thrown into a bush and forgotten about. Gandalf was not captured, he left before the dwarves and Bilbo woke up. After capturing the dwarves they were thinking of ways to eat them and hurting them, but out of nowhere a voice came and said he disagreed with the trolls ideas and they started fighting one another and as the time passed they forgot about the sun rise (trolls turn to stone if they are touched by sun light and not under the ground) and that is what happened to them and allowed the dwarves to escape. But the night got worse and soontwo giants were throwing boulders at each other so the dwarves with Bilbo and Gandalf had to find shelter again ,so they hurried to the closest mountain which was currently occupied by goblins , who were at a war with the elves. As they took shelter in the cave they slowly dozed off to sleep the goblins attacked in their sleep and were captured and sent to the goblin king when the others were captured Gandalf shot a flare and killed seven of them and followed the goblins down the tunnels in pitch black darkness. When they got to the goblin king, Gandalf came out of the darkness and pulled out a great sword (made by the elves that glowed when goblins are near) and stuck the king right in the heart, and all the goblins scared, ran as far as possible and allowed the dwarves and company to get away. When the dwarves ran to get away they didnt know the way because of two reasons, one reason is because it was pitch dark and there were so many tunnels soon after running down different tunnels the goblins soon chased them and caught up to them, and knocked down Dori who was carrying Bilbo, who was knocked down when a goblin tripped him and Bilbo was thrown down a hole and could not meet up with the others because he hit his head on the way down and the others took off without him. In the dark, all alone and not knowing where he was, crawling around on his knees he put his hand on something small, circular and cold and he slipped it into his pocket. Soon after awhile of crawling he fell into water and went fully under the water when he slipped out of the water. When Bilbo was dried off, he noticed a pair of eyes coming to him and was scared so he pulled out his dagger and told the monster to stop where he was and not to move, the monster was curious who he was and what he is doing in his tunnel. The monsters name was Gollum who was alive for many years. He would catch lost goblins and ones that strayed away from the group. Bilbo was very scared of the monster because he did not know what kind of creature it was or if it was hungry for Bilbo, so he asked the monster if he wanted to play a game with him. The game was to ask each other riddles and if Bilbo stumped Gollum he would have to show him the way out, but if Bilbo lost, Gollum could do any thing he wanted to him. Bilbo won of course but it was long and hard. So Gollum the loser, was very mad and decided to kill him anyway and do it very quick. So he said he had to go back to his island and look for something that would help him find the way when it would turn Gollum invisible and be able to kill Bilbo, but he could not find it because he dropped it in the tunnels catching a lost goblin and killing him. Gollum was furious and Bilbo was getting impatient waiting for him. The last riddle of Bilbos was what was in his pocket, which was Gollums present, the ring, and when Gollum had discovered it he began rowing as fast as he can towards Bilbo, to get his ring back. Bilbo slipped on the ring and was invisible but tripped over a loose root and Gollum ran right past him and Bilbo got up and followed him to the secret exit and found out that Bilbo didnt know the way so he sat down and waited for bilbo to show up when he was right behind him the whole time. So Bilbo had to escape, he ran back some and he jumped higher than any hobbit had ever jumped and cleared Gollums head by an inch and ran through the door and past the goblins. After he ran past the goblins there was one more tunnel he had to go through and he could see the light from the door but it was guarded with many goblins. He slipped in between their legs and their feet and tried to get out the look out window but he got stuck and with one hard push he was out but he lost his buttons and his belt ripped. The goblins where puzzled how the buttons had shown up and soon looked out the look out window and saw Bilbos shadow and so they chased him until he hid in the shadows of the trees. He ran for a good bit until he saw Bifur on look- out duty. When Bilbo was past him he took off his ring and they were all amazed how he had gotten out of the tunnels alive and he told the story (without including the ring) and they were all amazed and admired h im. After they woke up, they started on their way and Gandalf was leading them to an old friend of his. When they got to his land he told them that he was a skin changer and lived in a place with a lot of animals and rare plants. Gandalf told them to come two by two every five minutes or so and Bilbo was to come with Gandalf. When they found him he invited them and they told the story of what has happened so far and slowly the dwarves started to come in his house. After supper they all went to bed in a comfortable bed and dreamthorrible dreams about the goblins getting them in their sleep and all of them woke up in sweat. When Beorn came home from a walk he went to see if their story was true, it was so he lent them ponies and supplies and sent them on the way to Mirkwood , where he told them of the dangers and to stay on the path. When they got to the entrance of Mirkwood they had to send their ponies back and Gandalf did not follow them through Mirkwood he went back with the ponie s to Beorn. They camped that night at the entrance and when they woke up they would go in and follow the path and they did just that until they got to the first thing Beorn warned them about, the Black River, that if you drank from, touched or fell in you would forget all that you remembered or knew. They saw a boat up stream and threw a rope and got it as they brought it over they crossed the river two by two with Bombur going last because he was the fattest and when he was about to get up on the land a deer jumped out from a bush and kicked him into the river and as the dwarves shot at it, it was to late, the deer had already been far away and they had wasted arrows on it and Bombur was saved and brought up on land and was in a deep sleep and so they carried him from there until he would wake. Their rations where low and they where very hungry and tired when Bombur woke up from the long sleep and was hungry and they wished he would shut up and stop talking about the feast he had i n his dreams with the elf king. That night they took camp and Bilbo was to take guard, so he did. But slowly drifted to sleep and when he woke up he was alone and was trapped by a spiders web it was around his feet and he pulled out his knife and slashed the spider across his eyes and escaped to look for his friends when all the sudden he could hear spiders talking about the dwarves and how they where easy to capture except for one, and it was Thorin, who had killed a spider, but when he took count he saw that one was missing so he slipped on his ring and tricked the spiders by teasing them and calling them names. And so they chased after the voice and he left them in the woods and cut the dwarves down as easy as possible and let them free from the webs. After they got up Bilbo had told them about the ring and they didnt think less of him, they thought more of him, that he was a better burglar with it and after the story the dwarves where captured by elves, but Bilbo still had the r ing on so he didnt get caught and he could see where they where taking the dwarves. When the dwarves were sent to prison by the elf king they were fed. Bilbo was exploring the palace and he found out that Thorin had been captured as well. He had fully explored the palace and had memorized the passageways. When he heard of a great party coming up he thought of ways to get the dwarves out. He heard about a back door where empty barrels were dropped and it was a perfect chance so he got ready and made sure nothing would go wrong. When the party came, the elves who carried the keys had some special wine and it knocked them out and it was a sign for his plan to go in action, so he did and got all the dwarves even Thorin who was on the other side of the palace and then got them to the trap door and locked them in empty barrels and the door opened and the barrels were dropped into the water, but some hit the walls and edges and Bilbo jumped down and followed them in the cold water on a bar rel that kept on turning over. Right before they got to the Lake Town, where the barrels were suppose to go he gathered them up and checked them for the dwarves and found that most of them were bruised up and cut, others were cramped and stuffy and others were fine. When they went out to explore the area they saw village guards and out of nowhere Thorin popped out and said, I am Thorin Okensheild son of the king under the hill and I wish to speak with the king of this town. And the guards took him to the table where the king had been at a feast with some of the elf men. When the king gave them shelter and healed them and they regained their strength because their journey was about to come to an end, for they were going to go up the hill and find Smuag the dragon who killed the dwarves village and their king. And they were going to get back what was theirs the gold of the mountain. When they where fully healed the where escorted by the kings men until they got to the end of the river where the mountain started. When they got started up the mountain, they took camp because they wanted an early start on Smaug. As they slowly climbed the mountain they searched for the secret path that was on Thorins map and it was Bilbos job to find the way in. When they found the door they could not find the way to get it open so they sent Bilbo there and made him sit there until he found a way to get it open, but until then they searched for another way into the mountain. When they took camp on their seventh night on the mountain Bilbo saw a rock sticking out of a grassy area the moonlight shined on the rock and soon the wall behind him started to shake and crumble when Bilbo made a large scream for Thorin to put his key, which he held around his neck. When Thorin put the key in, the door swung up and it reeked and it was dark. They sent Bilbo in and he was very scared and didnt want to go alone but he did anyway, so as he slowly moved down the long tunnel he finally reached the other side where he saw a bright red and golden glow. There lay Smuag, with his wings under him and his tail curled around him and his long head on top of his tail. Bilbo slowly entered the room and took a large cup filled with wine that was still good and he brought it back to the dwarves and they drank that night and slept well. When they woke it was not pleasant and it had sounded like the mountain was going to explode. When Smuag flew high out of the mountain in a rage and saw the ponies and the old camps of the dwarves. The ponies fled with fear but most were caught and eaten. When the dragon returned and went back down to his chamber to wait for the thief to return and try to steal again but Bilbo was not that dumb, so he went to the entrance of the chamber and the dragon knew he was there, although he couldnt see him. His keen sense of smell had picked his scent up. The dragon knew he was traveling with the dwarves because he never forgot their taste but there was a new tast e with the dwarves and he couldnt find out what it was. Bilbo was at the doorway not daring to try and steal again but trying to see if the dragon was asleep. But when he looked in the far edge of the dragons left eye he could see the flame and the glare peeping out, looking for the thief, But he could not see him so he spoke out and said I know you are there, although I can not see you I know you are here so why dont you help yourself to more treasure thief. And with a scared reply he answered no thank you and soon they started to talk. And the dragon insisting on knowing who Bilbo was would constantly ask but Bilbo would answer in a smart remark, I am the barrel rider from the East who sneaks into your cave to catch you off guard to steal your marvelous treasure. And the dragon now knowing where he came from, because of his little hint barrel rider he now knows his next area to attack Lake Town. After that little hint, Bilbo started to get cocky. The dragon rose to the tunnel and with a snort he shot flames as hot as lava down the tunnel. The flames burned the hair on Bilbo from his head to his toes. Now, Bilbo going back to the dwarves, with the burns told them to close the door. For the dragon will destroy the whole side just to find them, so they closed the door, and just at that moment the dragon started his rage on the mountain. And it was just in time because if they didnt close the door they would have been crushed and killed. The dragon now out, was going to Lake Town, away from his chamber. There was a chance to let the dwarves explore the chamber and that is what they did. They found ancient armor and weapons strong enough to break solid gold. After getting the armor and weapons they wanted to get out, Thorin led them to the main gate. There, they went for an old look- out post, which was used back when Thorins father ruled. When the dragon reached Lake Town he was enraged and tried to destroy all that he could, burning buildings and houses. Smashi ng building with his tail and as the people fled even the great king fled. Few stayed to protect, one was a tall man by the name of Bard, an expert archer and was a descendant of the Lord of Dale, who used the dragons as messengers and could understand them and their weak points. Smuags weak spot was on his left breast. As the dragon made his third pass on the town, the ancient language came to Bard, and told him to shoot an arrow through the left breast scale of the dragon and he shall die. So with his last arrow that was given to him from his father, which Bard had always recovered it from high or low, was shot when the dragon passed by again. And down he went, into the lake around the town and the water was cold enough to put out the dragons flames forever. As the people started return to the town and the king did too, in shame, for he was one of the first people to leave. The people of Lake Town were sad, not for their homes but because they couldnt find Bard, the slayer of the dragon, but out of the fog there was a dark and tall man with a bow and a black arrow drenched in freezing cold water. After killing the dragon, Bard remembers the ancient treasure is in the mountain. Bard and some of the towns men go to find the treasure. He puts the treasure in barrels and travels to the city of Dale. Bard and the town men meet up with the dwarfs. Then Bard and the dwarfs talk about their ancestors. The dwarfs and the towns people start to rebuild Dale. And with some barrels of treasure, they reward Bilbo for his services, and escort him home. Words/ Pages : 3,761 / 24
