CHAPTER I

THE STAFF OF LIFE

With his nephews as willing companions and eager listeners, Uncle Paul

continued his walks and talks in the pleasant summer afternoons.

“Bread is made of flour,” he began, “and flour is wheat reduced to

powder under the millstone. What an interesting mechanism that is, the

flour-mill, driven by water, by the wind, sometimes by steam! What

wearisome effort, what waste of time, if we had not this invention and

were forced to do its work of grinding by sheer strength of arm!

“I must tell you that in ancient times, for want of knowing how to

grind wheat, people had to content themselves with crushing it between

two stones after parching it a little over the fire. The coarse meal

thus obtained was cooked in water to a sort of porridge and eaten with

no further preparation. Bread was unknown.

“Later the plan was hit upon of kneading the meal with water and of

cooking the dough between two hot stones. Thus was obtained a crude

sort of biscuit, about as thick as your finger, stodgy and hard, and

mixed with charcoal and ashes. It was preferable to the porridge, the

insipid paste, of the earlier time, but far inferior to the poorest

bread of to-day. To make a long story short, by trial after trial

success was at last attained in the making of bread like ours. It

became necessary then, without possessing anything to compare with our

mills, to grind wheat in large quantities.

“Flour was obtained by triturating the wheat in a hollowed stone with a

pestle. This latter was sometimes light enough to be operated directly

by hand; sometimes, to produce quicker results, it was so large and

heavy that it had to be turned in its stone mortar with the help of a

long bar. Such was the first mill. With appliances of this sort I leave

you to imagine how long a time was required for the production of a

single handful of flour. For bread enough to feed one person at one

meal, wretched slaves were kept toiling from morning till night and

from night till morning in turning the pestle.”

“What cruel masters they must have had!” exclaimed Emile.

“Yes, the slaves were harnessed to the bar like beasts of burden; and

when, weakened with fatigue, they did not go fast enough, a rawhide was

applied to their bare shoulders. These unfortunate millers were poor

wretches taken in war and afterward sold in the market with the same

indifference with which a drover sells his cattle. Such, then, were the

hardships that led the way to the modern mill which to-day, with a few

turns of its water-wheel, and to the cheerful accompaniment of its

tick-tack, can make flour enough for a whole family.

“But let us leave the mill and turn our attention to the following

interesting experiment. Take a handful of flour and with a little water

make it into dough. This done, knead the dough with your fingers over a

large plate while an assistant moistens it continually with water from

a pitcher. Keep the dough well in hand and continue kneading it,

flattening it out and gathering it together again, turning it over and

over under the fine stream of water poured from above.

“Examine carefully the water that passes over the dough and washes it.

It falls into the plate as white as milk, showing that it carries with

it something from the flour. This something will finally settle at the

bottom of the liquid, and we shall find it to be a substance not unlike

the starch used for starching linen. In fact, it is starch, or fecula,

as the chemists call it—neither more nor less. The starch used in the

laundry is obtained in considerable quantities by similar means: dough

is washed and the whitened water, left undisturbed, deposits a layer of

starch which has only to be gathered together and dried. [1]

“So much, then, is made clear: flour contains starch, but it contains

something else also. There is a limit beyond which the washed dough

yields no more starch; it is useless to knead it, the water falls

colorless into the plate. What remains in one’s hands after this

prolonged washing is a soft, gluey substance, having something of the

elastic quality of rubber. Grayish in color, it has a rather pronounced

odor. When dried in the sun, it becomes hard and translucent like horn.

It is called gluten from its gluelike character, its viscosity.

“Now this substance, so unattractive in appearance, all soft and sticky

and getting clogged between the fingers—this gluten, in short—do you

know what it is? Don’t try to dispute me, for what I am going to tell

you is the exact truth. In its composition gluten does not differ from

flesh. It is vegetable flesh, capable of becoming animal flesh by the

simple process of digestion, without any material loss or gain.

Therefore it is gluten, first and foremost, that gives to bread its

great nutritive value.

“Of all the cereals wheat contains the most gluten, with rye holding

second place. Maize and rice, as well as chestnuts and potatoes, are

wholly lacking in this ingredient; and for that reason flour made from

them, rich though it be in starch, is not at all the kind of flour for

bread. This will explain to you the superiority of wheat over all other

farinaceous grains.

“Wheat, the only cereal that can give us white bread, that superior

bread which nevertheless is not always to your taste unless spread with

a little butter, does not grow in all countries. Open your atlas and

run over with your finger the countries bordering on the Mediterranean;

your travels will embrace the principal regions where wheat flourishes.

Farther north it is too cold for the successful culture of the precious

cereal; farther south it is too warm.

“But that is not all. In the privileged regions not every district is

adapted to this incomparable crop: wheat needs the mild temperature and

fertile soil of the plains, not the harsh climate and dry slopes of the

mountains. Let us consider France in particular. Its plains produce

excellent wheat, but not enough to feed the entire population;

therefore in the hilly and cooler regions, where this cereal cannot be

raised, recourse is had in the first place to rye, which yields a bread

that is compact, brown, and heavy, but on the whole preferable to any

other except, of course, wheat. This rye bread is the customary food of

the country in the greater number of our departments.

“The raising of rye becomes in its turn impossible in regions too cold

and too sterile. There then remains, as a last resort, barley, the

hardiest of cereals, which is found in the mountains until we reach the

neighborhood of perpetual snow, and can be raised even in the frigid

climate of the extreme North.

“You ought to taste the miserable bread made from barley in order to

find our bread good—or, I might better say, in order to find it an

exquisite dainty even without butter or jam. Barley bread is full of

long bristles that stick in the throat; it contains more bran than

flour; it is bitter, stodgy, and of a disagreeable odor. Oh, what sorry

stuff! And yet many have to be content with it, and are only glad if

they can get enough of it.

“In the greater part of the world wheat, widely distributed by

commerce, furnishes bread only for the tables of the rich. The rest of

the population knows nothing, as a rule, of this article of food, has

never so much as seen it, and at most has only heard of it as a rare

curiosity. In place of bread the people eat here one thing, there

another, according to the country. Asia has rice, Africa millet,

America maize. In India and China the people have hardly anything to

eat but rice boiled in water with a little salt. Half the entire world

has practically the same diet.

“The plant that produces rice has a stalk resembling that of wheat, but

instead of ending in an upright ear it bears a cluster of feeble and

pendent branches, all loaded with seeds. The leaves are narrow and

ribbon-shaped, rough to the touch. This plant is aquatic. In order to

flourish, it must send down its roots into the submerged mud and spread

its foliage, excepting the tip, in the flood. Marshy shallows,

inundated a part of the year, are adapted to its cultivation.”

“But what do they do where there are no such marshes?” asked Louis.

“When such marshes are lacking, the ingenious Chinaman floods the

lowlands with water from some near-by stream until the ground is all

soft and muddy. He then draws off the water through a series of little

canals, and works the mud with a light plow drawn by a buffalo, a kind

of ox with a long beard hanging from its chin and a mane waving on its

back.

“The seed once sown in the furrows and the young plants started, the

water from the stream is again made to flood the fields, where it

remains until harvest time. Then for the second time it is drawn off,

and the reaper, sickle in hand and with the black mud up to his knees,

cuts down the rice-laden tops of the stalks.

“Maize, or Indian corn, is the staple food of South America, as rice is

that of Asia. Many call it Turkish wheat, a name doubly inappropriate,

for in the first place this grain is not indigenous to Turkey, but to

America, and in the second place it has nothing in common with the

wheat from which bread is made. From America its cultivation has spread

to our part of the globe.

“The ear of maize is very large and is composed of full, rounded

kernels, yellow and shiny, closely packed in regular rows. Like rice,

maize furnishes a fine flour of pleasing appearance but lacking in one

essential: it contains no gluten. Hence the utter impossibility of

using either rice or maize for making bread, despite the good

appearance of the flour made from them.

“Nevertheless maize is a very wholesome article of food, and one of

great value in the country, where the appetite is sharpened by open air

and hard work. Only it is not in the form of bread that it best yields

its nourishment, but rather in that of porridge, or boiled meal and

water.”
