Problem

How many grams of starch are present in a ¼ white camote?

Abstract

Sweet potato or as known as camote is a dicotyledonous plant which belongs to the family Convolvulaceae. Amongst the approximately 50 genera and more than 1000 species of this family, only batatas is a crop plant whose large, starchy, sweet tasting tuberous roots are an important root vegetable. The young leaves and shoots are sometimes eaten as greens. The sweet potato is only distantly related to the potato (Solanum tuberosum). It is commonly called a yam in parts of North America, although they are only very distantly related to the other plant widely known as yams) (in the Dioscoreaceae family), which is native to Africa and Asia. The roots are most frequently boiled, fried, or baked. They can also be processed to make starch and a partial flour substitute. Industrial uses include the production of starch and industrial alcohol. Although the leaves and shoots are also edible, the starchy tuberous roots are by far the most important product. In some tropical areas, they are a staple food-crop.

This plant is a herbaceous perennial vine, bearing alternate heart-shaped or palmately lobed leaves and medium-sized sympetalous flowers. The edible tuberous root is long and tapered, with a smooth skin whose color ranges between red, purple, brown and white. Its flesh ranges from white through yellow, orange, and purple.

Introduction

Starch or amylum (chemical formula (C6H10O5)) is a polysaccharide carbohydrate consisting of a large number of glucose units joined together by glycosidic bonds. Starch is produced by all green plants as an energy store and is a major food source for humans.Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. It consists of two types of molecules: the linear and helical amylose and the branched amylopectin. Depending on the plant, starch generally contains 20 to 25 percent amylose and 75 to 80 percent amylopectin.[1] Glycogen, the glucose store of animals, is a more branched version of amylopectin. The word "starch" is derived from Middle English sterchen, meaning to stiffen, which is appropriate since starch can be used as a thickening or glueing agent when dissolved in water and heated, giving wheatpaste.

Review of Related Literature

Starch is a dietary fiber, essential for health because it reduces overall hunger, by filling you up and inducing a hormonal response to shut off hunger. It helps control blood sugar levels, meaning more sustained energy and long-term heart protection.As a prebiotic, it selectively stimulates the growth and/or activity of healthy bacterias in the colon, and therefore boosts your immune system.Its fermentation in the large intestine produces beneficial fatty acids, including butyrate, which may block the body’s ability to burn carbohydrates and may protect the colon from cancer.

Advantages and disadvantages of camote

Sweet Potato or scientific of is also called a yam in USA but not really the true Yams. There is a confusion of this. Anyway Camote or sweet potato is propagated using the vine or stem as it is like a vines root crop. Camote grows in tropical area like Philippines, China, Africa and USA. It is used as food and vegetables. New leaves or shoot is uses as vegetable as it is green leafy vegetable and good for diet and a source of vitamin C, vitamin A and vitamin B6. It is also high in fiver and has iron and calcium to name a few.
The roots are boiled, fried or baked. It is interesting to note that sweet potato is good for diabetic person. It will help maintain the sugar level in your body and will lower insulin resistance.
Other used of Camote is used to substitute as a starch. You can make them into a candy, bake them like a cake, cook the leaves as viand or make a pie out of the root.
You can make a chips also out of the root.

Sweet potato varieties with dark orange flesh have more beta carotene than those with light colored flesh and their increased cultivation is being encouraged in Africa where Vitamin A deficiency is a serious health problem. Despite the name "sweet", it may be a beneficial food for diabetics, as preliminary studies on animals have revealed that it helps to stabilize blood sugar levels and to lower insulin resistance. Some Americans, including television personality Oprah Winfrey, are advocating increased consumption of sweet potatoes both for their health benefits and because of their importance in traditional Southern cuisine.

There are no disadvantages in camote or sweet potato.

Procedure

The materials needed for this experiment is ¼ white sweet potato, knife, grinding machine, mortar and pestle.

The sweet potato was been peeled and sliced using the knife.

The peeled sweet potatoes were sliced into thin pieces.


Small plywood was used for drying the sliced sweet potatoes.

After drying the sweet potatoes a grinding machine was used in grinding. To soften the ground sweet potato, mortar and pestle was used in pounding.



Upon following the procedures above, starch was extracted from camote/ sweet potatoes. Besides simple starches, sweet potatoes are rich in complex carbohydrates, dietary fiber, beta carotene (a vitamin A equivalent nutrient), vitamin C, and vitamin B6.

We found out that the starch extracted from sweet potatoes is healthier to use than the starch sold in department stores for it undergo chemical processes.

Result and Discussion

The researchers were able to get the amount of starch present in a ¼ white camote. Flour from sweet potatoes is high in fiber and contains a higher level of carbohydrates and lower level of protein than common wheat flour.

It can be used for baked goods, such as breads, cookies, muffins, pancakes, and doughnuts, and as a thickener for sauces and gravies. Commonly used in gluten free cooking and baking.

Conclusion

The amount of grams of a starch that came from the ¼ sweet potato (camote) is 96.5g.

Recommendation

For the next researchers who would like to do our study we recommend them to repeat the procedure for 2 or more times to have an accurate results.

Do the experiment by group and never depend only on one person to do the experiment. And as possible have some research in the internet or books, and never concentrate to one source only as possible have as many sources you could have to help you in having an accurate result.

Problem:

How much citric acid content is present in a ripe mango?

Abstract:

Mangoes belong to the genus Mangifera, consisting of numerous species of tropical

fruiting trees in the flowering plant family Anacardiaceae. The mango is indigenous to

the Indian Subcontinent especially India, Pakistan, Bangladesh, and Southeast Asia.

Cultivated in many tropical regions and distributed widely in the world, mango is one of

the most extensively exploited fruits for food, juice, flavor, fragrance and color, making it

a common ingredient in new functional foods often called superfruits. Its leaves are

ritually used as floral decorations at weddings and religious ceremonies.

Introduction:

Citric acid is a white crystalline powder. It can exist either in an anhydrous

(water-free) form or as a monohydrate. The anhydrous form crystallizes from hot water,

whereas the monohydrate forms when citric acid is crystallized from cold water. The

monohydrate can be converted to the anhydrous form by heating it above 78 °C. Citric

acid also dissolves in absolute (anhydrous) ethanol (76 parts of citric acid per 100 parts of

ethanol) at 15 degrees Celsius.

In chemical structure, citric acid shares the properties of other carboxylic acids. When

heated above 97°C, it decomposes through the loss of carbon dioxide and water.

Review of related literature:

Citric acid is a weak organic acid, and it is a natural preservative and is also used to add an acidic, or sour, taste to foods and soft drinks. In biochemistry, it is important as an intermediate in the citric acid cycle and therefore occurs in the metabolism of almost all living things. It also serves as an environmentally benign cleaning agent and acts as an antioxidant and a lubricant.

Citric acid exists in a variety of fruits and vegetables, most notably citrus fruits. Lemons and limes have particularly high concentrations of the acid; it can constitute as much as 8% of the dry weight of these fruits (1.44 and 1.38 grams per ounce of the juices, respectively). The concentrations of citric acid in citrus fruits range from .005 mol/L for oranges and grapefruits to .030 mol/L in lemons and limes. These values will vary depending on the circumstances in which the fruit was grown.

Procedure:

All the materials were prepared needed for the experiment. First is a need to pick mangoes that are firm, The mango was squeezed a little so that it would be soft and they turn too mush, too firm mangoes have stone in their center, and that's what make them trickery to cut up. The stone were flatted oval; the mangoes were narrower one way than the other in alignment with the stone. The mangoes were washed and took the stickers off... Begin by turning the mango up on this skinny side. The mangoes cheek was cut off, as close to the stone as possible. If the stone was hit, it may usually just serve around it a little. The other cheek was cut; a cheek was taken and sliced the meat of the fruit all the way down to the skin. But not through it be careful. The skin was pretty thick, and it’s not likely cut yourself. The other from now was cut to make a grid. The cheek was flipped inside out so that the fruit now splays out in "cubes" then peel the fruit off. Do this over and over, whatever put the fruit into, as it likely to drip if the mango. If the mango is too ripe, at this stage it wont be able to peel of chunks, but rather than it will find yourself squeezing off mush. The cheeks were put both in the blender here. Now it had all the fruit off mango that can be use. The juice was place of the mango inside the beaker and heats it until it boils. The remaining juice was put it in the titration kit, measure it using acid basses titration. The titrant was used as a calibrated burette to add, it is possible to determine the exact amount that has been consumed when the endpoint is reached. The endpoint was the point at which the titration is complete, as determined by an indicator. This was ideally the same volume as the equivalence point - the volume of added titrant at which the number of moles of titrant is equal to the number of moles of analyte, or some multiple thereof (as in polyprotic acids).

Result and discussion:

Citric acid is the most widely used organic acidulate and pH-control agent. This is

probably due to the fact that it is a WEAK acid. If it was a strong acid it would probably

take out a couple teeth as you gulp it down in your soda

Citrates also aid in the help of alcoholics. Since citric acid IS an acid and a

property of acid is a sour taste. Citric acid is added to a lot of beverages and medications.

Conclusion:

The amount of grams of a citric acid that came from the 3/4 ripe mango is 241.25 g.

Recommendation:

Do the experiment by group and never depend only on one person to do the experiment. And as possible have some research in the library or old books, and have as much time to spend and do the investigatory project early as possible. Have as many bibliographies as possible to have as many ideas.

English (Song to Celia)

Song To Celia
by Ben Jonson

Drink to me, only with thine eyes
And I will pledge with mine;
Or leave a kiss but in the cup,
And I'll not look for wine.
The thirst that from the soul doth rise
Doth ask a drink divine:
But might I of Jove's nectar sup
I would not change for thine.
I sent thee late a rosy wreath,
Not so much honouring thee
As giving it a hope that there
It could not withered be
But thou thereon didst only breath
And sent'st it back to me:
Since, when it grows and smells, I swear,
Not of itself but thee.







Melvin’s Line 1- 4

Drink to me, only with thine eyes
And I will pledge with mine;
Or leave a kiss but in the cup,
And I'll not look for wine.

Paraphrase
The speaker in "Song to Celia" opens with a plea for his lady to express her love by gazing upon him. His plea is assertive, in the form of a command to drink to him with her eyes. He wants more than an expression of her love, however; he wants a pledge. He notes this in the second line when he declares that he will return the pledge with his own eyes. The reference to the cup that is commonly filled with wine becomes an apt metaphor for what he is asking from his lady. One usually makes a toast, a pledge of some sort, when first sipping a cup of wine. The speaker wants his lady to make a pledge to him with her eyes rather than while drinking from a cup of wine. This pledge would be more personal and so more meaningful to him.









Bryan’s Line 5 - 8
The thirst that from the soul doth rise
Doth ask a drink divine:
But might I of Jove's nectar sup
I would not change for thine.
Paraphrase
The speaker insists that if his lady would leave a kiss for him in the cup, he would prize it more than nectar from the gods. He claims that his soul "thirsts" for love and that only "a drink divine" that transcends even Jove's nectar can quench it. "Jove" refers to the god Jupiter, lord of the classical gods and a recurrent symbol of divinity in secular poetry. The gods drank heavenly nectar far finer than any wine mortals drank.

Hip Hop History

Jamaican born DJ Clive "Kool Herc" Campbell is credited as originating hip hop music, in the Bronx, New York, after moving to New York at the age of thirteen. Herc created the blueprint for hip hop music and culture by building upon the Jamaican tradition of toasting, or boasting impromptu poetry and sayings over music, which he witnessed as a youth in Jamaica.Herc and other DJs would tap into the power lines to connect their equipment and perform, at venues such as public basketball courts and the historic building "where hip hop was born," 1520 Sedgwick Avenue, Bronx, New York. [8] Their equipment was composed of huge stacks of speakers, turntables, and one or more microphones.[9] In late 1979, Debbie Harry of Blondie took Chic co-founder and lead guitarist Nile Rodgers to such an event, as the main backing track used was the break from Chic's "Good Times". Herc was also the developer of break-beat deejaying, where the breaks of funk songs—the part most suited to dance, usually percussion-based—were isolated and repeated for the purpose of all-night dance parties. This breakbeat DJing, using hard funk, rock, and records with Latin percussion, formed the basis of hip hop music. Campbell's announcements and exhortations to dancers would lead to the syncopated, rhymed spoken accompaniment we now know as rapping. He dubbed his dancers break-boys and break-girls, or simply b-boys and b-girls. According to Herc, "breaking" was also street slang for "getting excited" and "acting energetically". Herc's terms b-boy, b-girl and breaking became part of the lexicon of hip hop culture, before that culture itself had developed a name. Later DJs such as Grand Wizard Theodore, Grandmaster Flash and Jazzy Jay refined and developed the use of breakbeats, including cutting and scratching.The approach used by Herc was soon widely copied, and by the late 1970s DJs were releasing 12" records where they would rap to the beat. Popular tunes included Kurtis Blow's "The Breaks", and The Sugar Hill Gang's "Rapper's Delight." Emceeing is the rhythmic spoken delivery of rhymes and wordplay, delivered over a beat or without accompaniment. Rapping is derived from the griots (folk poets) of West Africa, and Jamaican-style toasting. Rap developed both inside and outside of hip hop culture, and began with the street parties thrown in the Bronx neighborhood of New York in the 1970s by Kool Herc and others. It originated as MCs would talk over the music to promote their DJ, promote other dance parties, take light-hearted jabs at other lyricists, or talk about problems in their areas and issues facing the community as a whole. Melle Mel, a rapper/lyricist with The Furious Five, is often credited with being the first rap lyricist to call himself an "MC". Hip hop as a culture was further defined in 1983, when Afrika Bambaataa and the Soulsonic Force released a track called "Planet Rock." Instead of simply rapping over disco beats, Bambaataa created an innovative electronic sound, taking advantage of the rapidly improving drum machine and synthesizer technology. The appearance of music videos changed entertainment: they often glorified urban neighborhoods. The music video for "Planet Rock" showcased the subculture of hip hop musicians, graffiti artists and breakdancers. Many hip hop-related films were released between 1983 and 1985, among them Wild Style, Beat Street, Krush Groove, Breakin, and the documentary Style Wars. These films expanded the appeal of hip hop beyond the boundaries of New York. By 1985, youth worldwide were laying down scrap linoleum or cardboard, setting down portable "boombox" stereos and spinning on their backs in Adidas tracksuits and sneakers to music by Run DMC, LL Cool J, the Fat Boys, Herbie Hancock, EPMD, Soulsonic Force, Jazzy Jay, Dr. Jeckyll and Mr. Hyde, and Stetsasonic, just to name a few. The hip hop artwork and "slang" of US urban communities quickly found its way to Europe and Asia, as the culture's global appeal took root. The 1980s also saw many artists make social statements through hip hop. In 1982, Melle Mel and Duke Bootee recorded "The Message" (officially credited to Grandmaster Flash & The Furious Five), a song that foreshadowed the socially conscious statements of Run-DMC's "It's like That" and Public Enemy's "Black Steel in the Hour of Chaos." During the 1980s, hip hop also embraced the creation of rhythm by using the human body, via the vocal percussion technique of beatboxing. Early pioneers such as Doug E. Fresh, Biz Markie, and Buffy from the Fat Boys made beats, rhythm, and musical sounds using their mouth, lips, tongue, voice, and other body parts. "Human Beatbox" artists would also sing or imitate turntablism scratching or other instrument sounds.

The Necklace

She was one of those pretty and charming girls born, as though fate had blundered over her, into a family of artisans. She had no marriage portion, no expectations, no means of getting known, understood, loved, and wedded by a man of wealth and distinction; and she let herself be married off to a little clerk in the Ministry of Education. Her tastes were simple because she had never been able to afford any other, but she was as unhappy as though she had married beneath her; for women have no caste or class, their beauty, grace, and charm serving them for birth or family, their natural delicacy, their instinctive elegance, their nimbleness of wit, are their only mark of rank, and put the slum girl on a level with the highest lady in the land.
She suffered endlessly, feeling herself born for every delicacy and luxury. She suffered from the poorness of her house, from its mean walls, worn chairs, and ugly curtains. All these things, of which other women of her class would not even have been aware, tormented and insulted her. The sight of the little Breton girl who came to do the work in her little house aroused heart-broken regrets and hopeless dreams in her mind. She imagined silent antechambers, heavy with Oriental tapestries, lit by torches in lofty bronze sockets, with two tall footmen in knee-breeches sleeping in large arm-chairs, overcome by the heavy warmth of the stove. She imagined vast saloons hung with antique silks, exquisite pieces of furniture supporting priceless ornaments, and small, charming, perfumed rooms, created just for little parties of intimate friends, men who were famous and sought after, whose homage roused every other woman's envious longings.
When she sat down for dinner at the round table covered with a three-days-old cloth, opposite her husband, who took the cover off the soup-tureen, exclaiming delightedly: "Aha! Scotch broth! What could be better?" she imagined delicate meals, gleaming silver, tapestries peopling the walls with folk of a past age and strange birds in faery forests; she imagined delicate food served in marvellous dishes, murmured gallantries, listened to with an inscrutable smile as one trifled with the rosy flesh of trout or wings of asparagus chicken.
She had no clothes, no jewels, nothing. And these were the only things she loved; she felt that she was made for them. She had longed so eagerly to charm, to be desired, to be wildly attractive and sought after.

She had a rich friend, an old school friend whom she refused to visit, because she suffered so keenly when she returned home. She would weep whole days, with grief, regret, despair, and misery.

One evening her husband came home with an exultant air, holding a large envelope in his hand.
"Here's something for you," he said.
Swiftly she tore the paper and drew out a printed card on which were these words:
"The Minister of Education and Madame Ramponneau request the pleasure of the company of Monsieur and Madame Loisel at the Ministry on the evening of Monday, January the 18th."
Instead of being delighted, as her husband hoped, she flung the invitation petulantly across the table, murmuring:
"What do you want me to do with this?"
"Why, darling, I thought you'd be pleased. You never go out, and this is a great occasion. I had tremendous trouble to get it. Every one wants one; it's very select, and very few go to the clerks. You'll see all the really big people there."
She looked at him out of furious eyes, and said impatiently: "And what do you suppose I am to wear at such an affair?"
He had not thought about it; he stammered:
"Why, the dress you go to the theatre in. It looks very nice, to me . . ."
He stopped, stupefied and utterly at a loss when he saw that his wife was beginning to cry. Two large tears ran slowly down from the corners of her eyes towards the corners of her mouth.
"What's the matter with you? What's the matter with you?" he faltered.
But with a violent effort she overcame her grief and replied in a calm voice, wiping her wet cheeks:
"Nothing. Only I haven't a dress and so I can't go to this party. Give your invitation to some friend of yours whose wife will be turned out better than I shall."
He was heart-broken.
"Look here, Mathilde," he persisted. "What would be the cost of a suitable dress, which you could use on other occasions as well, something very simple?"
She thought for several seconds, reckoning up prices and also wondering for how large a sum she could ask without bringing upon herself an immediate refusal and an exclamation of horror from the careful-minded clerk.

At last she replied with some hesitation:
"I don't know exactly, but I think I could do it on four hundred francs."
He grew slightly pale, for this was exactly the amount he had been saving for a gun, intending to get a little shooting next summer on the plain of Nanterre with some friends who went lark-shooting there on Sundays.
Nevertheless he said: "Very well. I'll give you four hundred francs. But try and get a really nice dress with the money."
The day of the party drew near, and Madame Loisel seemed sad, uneasy and anxious. Her dress was ready, however. One evening her husband said to her:
"What's the matter with you? You've been very odd for the last three days."
"I'm utterly miserable at not having any jewels, not a single stone, to wear," she replied. "I shall look absolutely no one. I would almost rather not go to the party."
"Wear flowers," he said. "They're very smart at this time of the year. For ten francs you could get two or three gorgeous roses."
She was not convinced.
"No . . . there's nothing so humiliating as looking poor in the middle of a lot of rich women."
"How stupid you are!" exclaimed her husband. "Go and see Madame Forestier and ask her to lend you some jewels. You know her quite well enough for that."
She uttered a cry of delight.
"That's true. I never thought of it."
Next day she went to see her friend and told her her trouble.
Madame Forestier went to her dressing-table, took up a large box, brought it to Madame Loisel, opened it, and said:
"Choose, my dear."
First she saw some bracelets, then a pearl necklace, then a Venetian cross in gold and gems, of exquisite workmanship. She tried the effect of the jewels before the mirror, hesitating, unable to make up her mind to leave them, to give them up. She kept on asking:
"Haven't you anything else?"
"Yes. Look for yourself. I don't know what you would like best."
Suddenly she discovered, in a black satin case, a superb diamond necklace; her heart began to beat covetously. Her hands trembled as she lifted it. She fastened it round her neck, upon her high dress, and remained in ecstasy at sight of herself.

Then, with hesitation, she asked in anguish:
"Could you lend me this, just this alone?"
"Yes, of course."
She flung herself on her friend's breast, embraced her frenziedly, and went away with her treasure. The day of the party arrived. Madame Loisel was a success. She was the prettiest woman present, elegant, graceful, smiling, and quite above herself with happiness. All the men stared at her, inquired her name, and asked to be introduced to her. All the Under-Secretaries of State were eager to waltz with her. The Minister noticed her.
She danced madly, ecstatically, drunk with pleasure, with no thought for anything, in the triumph of her beauty, in the pride of her success, in a cloud of happiness made up of this universal homage and admiration, of the desires she had aroused, of the completeness of a victory so dear to her feminine heart.
She left about four o'clock in the morning. Since midnight her husband had been dozing in a deserted little room, in company with three other men whose wives were having a good time. He threw over her shoulders the garments he had brought for them to go home in, modest everyday clothes, whose poverty clashed with the beauty of the ball-dress. She was conscious of this and was anxious to hurry away, so that she should not be noticed by the other women putting on their costly furs.
Loisel restrained her.
"Wait a little. You'll catch cold in the open. I'm going to fetch a cab."
But she did not listen to him and rapidly descended the staircase. When they were out in the street they could not find a cab; they began to look for one, shouting at the drivers whom they saw passing in the distance.
They walked down towards the Seine, desperate and shivering. At last they found on the quay one of those old nightprowling carriages which are only to be seen in Paris after dark, as though they were ashamed of their shabbiness in the daylight.
It brought them to their door in the Rue des Martyrs, and sadly they walked up to their own apartment. It was the end, for her. As for him, he was thinking that he must be at the office at ten.
She took off the garments in which she had wrapped her shoulders, so as to see herself in all her glory before the mirror. But suddenly she uttered a cry. The necklace was no longer round her neck!

"What's the matter with you?" asked her husband, already half undressed.
She turned towards him in the utmost distress.
"I . . . I . . . I've no longer got Madame Forestier's necklace. . . ."
He started with astonishment.
"What! . . . Impossible!"
They searched in the folds of her dress, in the folds of the coat, in the pockets, everywhere. They could not find it.
"Are you sure that you still had it on when you came away from the ball?" he asked.
"Yes, I touched it in the hall at the Ministry."
"But if you had lost it in the street, we should have heard it fall."
"Yes. Probably we should. Did you take the number of the cab?"
"No. You didn't notice it, did you?"
"No."
They stared at one another, dumbfounded. At last Loisel put on his clothes again.
"I'll go over all the ground we walked," he said, "and see if I can't find it."
And he went out. She remained in her evening clothes, lacking strength to get into bed, huddled on a chair, without volition or power of thought.
Her husband returned about seven. He had found nothing.
He went to the police station, to the newspapers, to offer a reward, to the cab companies, everywhere that a ray of hope impelled him.
She waited all day long, in the same state of bewilderment at this fearful catastrophe.
Loisel came home at night, his face lined and pale; he had discovered nothing.
"You must write to your friend," he said, "and tell her that you've broken the clasp of her necklace and are getting it mended. That will give us time to look about us."
She wrote at his dictation.

By the end of a week they had lost all hope.
Loisel, who had aged five years, declared:
"We must see about replacing the diamonds."
Next day they took the box which had held the necklace and went to the jewellers whose name was inside. He consulted his books.
"It was not I who sold this necklace, Madame; I must have merely supplied the clasp."
Then they went from jeweller to jeweller, searching for another necklace like the first, consulting their memories, both ill with remorse and anguish of mind.
In a shop at the Palais-Royal they found a string of diamonds which seemed to them exactly like the one they were looking for. It was worth forty thousand francs. They were allowed to have it for thirty-six thousand.

They begged the jeweller not to sell it for three days. And they arranged matters on the understanding that it would be taken back for thirty-four thousand francs, if the first one were found before the end of February.
Loisel possessed eighteen thousand francs left to him by his father. He intended to borrow the rest.
He did borrow it, getting a thousand from one man, five hundred from another, five louis here, three louis there. He gave notes of hand, entered into ruinous agreements, did business with usurers and the whole tribe of money-lenders. He mortgaged the whole remaining years of his existence, risked his signature without even knowing if he could honour it, and, appalled at the agonising face of the future, at the black misery about to fall upon him, at the prospect of every possible physical privation and moral torture, he went to get the new necklace and put down upon the jeweller's counter thirty-six thousand francs.
When Madame Loisel took back the necklace to Madame Forestier, the latter said to her in a chilly voice:
"You ought to have brought it back sooner; I might have needed it."
She did not, as her friend had feared, open the case. If she had noticed the substitution, what would she have thought? What would she have said? Would she not have taken her for a thief?

Madame Loisel came to know the ghastly life of abject poverty. From the very first she played her part heroically. This fearful debt must be paid off. She would pay it. The servant was dismissed. They changed their flat; they took a garret under the roof.
She came to know the heavy work of the house, the hateful duties of the kitchen. She washed the plates, wearing out her pink nails on the coarse pottery and the bottoms of pans. She washed the dirty linen, the shirts and dish-cloths, and hung them out to dry on a string; every morning she took the dustbin down into the street and carried up the water, stopping on each landing to get her breath. And, clad like a poor woman, she went to the fruiterer, to the grocer, to the butcher, a basket on her arm, haggling, insulted, fighting for every wretched halfpenny of her money.
Every month notes had to be paid off, others renewed, time gained.

Her husband worked in the evenings at putting straight a merchant's accounts, and often at night he did copying at twopence-halfpenny a page.
And this life lasted ten years.
At the end of ten years everything was paid off, everything, the usurer's charges and the accumulation of superimposed interest.
Madame Loisel looked old now. She had become like all the other strong, hard, coarse women of poor households. Her hair was badly done, her skirts were awry, her hands were red. She spoke in a shrill voice, and the water slopped all over the floor when she scrubbed it. But sometimes, when her husband was at the office, she sat down by the window and thought of that evening long ago, of the ball at which she had been so beautiful and so much admired.
What would have happened if she had never lost those jewels. Who knows? Who knows? How strange life is, how fickle! How little is needed to ruin or to save!
One Sunday, as she had gone for a walk along the Champs-Elysees to freshen herself after the labours of the week, she caught sight suddenly of a woman who was taking a child out for a walk. It was Madame Forestier, still young, still beautiful, still attractive.
Madame Loisel was conscious of some emotion. Should she speak to her? Yes, certainly. And now that she had paid, she would tell her all. Why not?
She went up to her.
"Good morning, Jeanne."
The other did not recognise her, and was surprised at being thus familiarly addressed by a poor woman.
"But . . . Madame . . ." she stammered. "I don't know . . . you must be making a mistake."
"No . . . I am Mathilde Loisel."
Her friend uttered a cry.
"Oh! . . . my poor Mathilde, how you have changed! . . ."
"Yes, I've had some hard times since I saw you last; and many sorrows . . . and all on your account."
"On my account! . . . How was that?"
"You remember the diamond necklace you lent me for the ball at the Ministry?"
"Yes. Well?"
"Well, I lost it."
"How could you? Why, you brought it back."
"I brought you another one just like it. And for the last ten years we have been paying for it. You realise it wasn't easy for us; we had no money. . . . Well, it's paid for at last, and I'm glad indeed."

Madame Forestier had halted.
"You say you bought a diamond necklace to replace mine?"
"Yes. You hadn't noticed it? They were very much alike."
And she smiled in proud and innocent happiness.
Madame Forestier, deeply moved, took her two hands.
"Oh, my poor Mathilde! But mine was imitation. It was worth at the very most five hundred francs! . . . "
