THE LITTLE FEATHERED BOYS AND GIRLS.

In fragrant fields where graze the herds

And all along the old highway,

The boys and girls among the birds

Call each to each the livelong day.

Bob White, Bob White, pipes out the quail

From old fence posts and mossy stones,

In meadows where the ripened grain

In golden stacks awaits the flail.

A little tuft of feathers grey

That snaps its bill in eager glee

When e’er a fly is caught on wing,

Full forty times calls out Phoebe.

When fragrant dews fall from the sky—

And sinks the sun behind the hill,

From dark’ning woods rings out the cry,

O Whip poor Will—O Whip poor Will.

THE COTTON PLANT.

(_Gossypium barbadense_, L.)

Theise men ben the beste worchers of Gold, Sylver, Cottoun, Sylk and

of all such things of any other, that be in the World.

—Mandeville, Travels, p. 212.

The cotton plant is undoubtedly one of the most useful plants in the

entire vegetable kingdom. As with other exceedingly useful, though

common things, we are so accustomed to the blessings we owe to this

plant that we almost entirely lose sight of its identity and very

existence.

There are a number of cotton yielding plants which belong to the genus

Gossypium of the Mallow family (Malvaceæ), the same family to which the

Hibiscus and garden mallows belong. The most important species are G.

barbadense, which yields the noted Sea Island cotton, and G. herbaceum.

Both are extensively cultivated in the United States, the latter species

more than the former. Other more or less cultivated species are G.

arboreum, G. religiosum and G. punctatum. The cottons are handsome

plants with large, showy yellow or purple flowers. They vary from

comparatively small and herbaceous to shrubby or even approaching the

dimensions of trees. The seeds are borne in a three to five lobed

capsule, which ruptures at maturity, thus allowing the snow-white cotton

head to appear. The outer surface of the seeds is covered with slender

fibers, each fiber being simply a single, greatly elongated epidermal

cell. The individual fiber is flattened, twisted upon its axis,

flexuous, from one to two or three inches in length. These fibers

constitute the cotton of the market, which finds so many important uses

in human economy. Of course primarily nature intended these fibers for

the special use of the plant itself; being a means of aiding in the

distribution of the seeds, and no doubt also serving as a protection

against being eaten by animals, as the dense, more or less intertwined

growth of insipid, tenacious fibers constitute anything but a tempting

morsel. Man, by his ingenuity and skill, has been enabled to utilize

this product of nature in his own behalf.

The commercial and technical uses of cotton date back to very remote

antiquity. Cotton fabrics were in use in China as early as 2300 B. C. At

the discovery of America, beautiful cotton fabrics were found in Brazil,

Peru, Mexico and the West Indies. According to the eminent Greek

historian and traveler, Herodotus, cotton clothing was quite universally

worn 484 B. C. The finest cloth came from the valleys of the Ganges, and

not until the close of the campaigns of Alexander the Great did the

manufacture of cotton cloth become a distinctive industry in Greece. It

appears that during the time of Pharaoh cotton was yet a rare article

since it is recorded that this eminent ruler presented Joseph with a

costly coat made of this material, as a memento of high esteem. It is

also a notable fact that the Egyptian mummies are swathed in linen

instead of cotton cloth. No cotton seeds have ever been found in the

ancient tombs of Egypt, nor is the plant represented upon the ancient

mural paintings of that country.

In the eastern continent India was no doubt the principal cotton growing

country; even China obtained its principal supply from that source. Not

until about the ninth century of our era was cotton extensively

cultivated in China. About the second century Arabian merchants brought

cotton from India and began to cultivate it in the vicinity of the Red

Sea, and from thence it gradually found its way into Spain about the

sixteenth century, and from Spain into Italy and Greece.

No one knows exactly when cotton began to be used and cultivated in the

western continent; we know that it must have been used a long time

before the discovery of America by Columbus, for reasons already given.

Mexican and South American mummy cloth is found to consist largely of

cotton.

Cotton is now extensively cultivated in the warmer countries of both

hemi-spheres—in the southern United States since the sixteenth century.

The cotton plant is in reality a perennial, becoming quite shrubby with

age, but in cultivation it is treated as an annual, being grown from

seeds planted each spring. Three or four seeds are planted to each hill,

the hills being about three feet apart. After sprouting the weaker

individuals are removed, and at the end of three or four months the

remaining carefully cultivated plants are pruned to make them more

spreading and give a better yield of cotton. The plants grow quite

rapidly, the cotton maturing about five months after planting. With the

exception of the pruning, the planting and cultivation of cotton in the

southern states is not unlike the planting and cultivation of corn in

the middle states.

The cotton is picked by hand into bags or baskets, spread out and dried,

and finally carted to the cotton gin, a machine invented by Eli Whitney

(1793), which separates the fibers from the seeds. The cotton is now

pressed into bales, weighing from 400 to 500 pounds, for shipment. The

cotton fiber is subjected to further processes of cleaning, carding,

etc., before it is ready to be manufactured into cloth fabrics, thread,

etc.

Nearly all parts of the cotton plant find a use. After the cotton is

picked, the stalks are burnt upon the fields or “plowed under” to serve

as a fertilizer for the soil, which would otherwise become impoverished

very rapidly. The bark of the root is collected and employed

medicinally, its medicinal properties being highly lauded by the negroes

of the South. The seeds yield the cottonseed oil, which is not unlike

olive oil. This oil, however, varies in purity, the purest being used as

an adulterant of olive oil or as a substitute for this oil. The less

pure grades are used for burning, but more in the preparation of woollen

cloth and morocco leather, also as a lubricant for machinery. It is also

used as a substitute for almond oil and olive oil in many pharmaceutical

preparations and in the manufacture of soap. The seeds from which the

oil has been expressed constitute the cottonseed cake, used as a

nutritious cattle fodder. In the South a tea made from the seeds is

considered a useful remedy in the treatment of malaria and dysentery. A

tea made from the leaves is much used medicinally in Jamaica and other

islands of the West Indies.

It is, however, the fiber, or cotton, which is the important part of the

plant. It would be a tedious and difficult task to describe, or even

enumerate, all of the uses to which it is put. It is used as wadding in

clothing and quilts. It is used by the bacteriologist in the filtration

of air; air passed through a layer of cotton is germ free. It is also

used in the filtration of liquids. Purified and variously prepared,

cotton is almost indispensable in surgery. It forms an excellent

protective covering for wounds, ulcers, burns and scalds. It absorbs

secretions and arrests hemorrhages. It is used in the preparation of gun

cotton (pyroxylin) nitro-cellulose, collodion and flexible collodion.

Gun cotton is prepared by treating cotton with strong nitric acid and is

used in gunnery, blasting and in photography. Collodion (collodium) and

flexible collodion are used in surgery, in the treatment of ulcers, skin

diseases, to arrest hemorrhages, applied to inflamed areas, etc.

The most important part of the entire plant is the fiber or cotton as it

is used in the manufacture of cloth. The modern method of cotton

manufacture does not date back further than 1760. Prior to that time

weaving and spinning were altogether domestic. At first the work was

done by means of the ancient distaff and spindle, more recently the

spinning wheel. By these only one thread could be produced at a time

and, as may be imagined, the process was very slow. Furthermore, the

yarn produced was inferior. A fairly good thread could be spun from

flax, but the softness, shortness and unevenness of the cotton fiber

made it difficult to produce a good uniform yarn by means of such crude

apparatus. In fact, so poor was the yarn produced that in weaving it was

used only for the weft (transverse thread), while linen, woolen or

worsted yarn was used for the warp (longitudinal thread), in order that

the cloth might have sufficient durability. During the middle of the

eighteenth century the machinery for spinning was much more imperfect

than the machinery for weaving. As a consequence, it became necessary to

produce better spinning machines. In 1767 Hargreaves invented the

“jenny” which spun eight threads at a time. In 1769 Arkwright invented

the “waterframe,” or “throstle,” by means of which a much firmer yarn

was produced. In 1785 Dr. Cartwright invented the “power loom,” which

far surpassed any previous spinning machine. Other improvements were

added from time to time, culminating in our highly perfected modern

machines, which would require volumes for a complete description. We

have machines with thousands of spindles. It is possible to weave a

thread one thousand miles or more in length, yet weighing but one pound.

The raw cotton must be subjected to various processes before it is ready

for spinning. The bales are opened and the cotton sorted, so as to

insure a uniform quality. It is then passed through a scutching,

willowing or cleaning machine, where all impurities and undesirable

foreign particles are removed. Next it is passed through a carding

machine, which straightens out the fibers and lays them parallel. It

also passes through the spreading machine, roving machine and finally to

the spinning machine.

The finer yarns are spun from Sea Island cotton, from which fine

muslins, laces, etc., are made. This cotton has long fibers. The good

qualities of short cottons are used in the manufacture of cambrics,

calicoes, sheetings, shirtings, etc. Inferior grades of cotton are used

for coarse yarns in the manufacture of coarse fabrics. Cotton is also

mixed with wool. Yorkshire broadcloth is said to be about half cotton.

From warps of cotton and wefts of wool or worsted (a variety of wool)

are formed Orleans cloths, Coburgs, mousselines de laine, damasks, etc.

There are also fabrics composed of silk and cotton, linen and cotton,

alpaca and cotton, etc. It is used in the manufacture of cotton thread

for sewing and pack thread for tying bundles, and other cordage.
