No other material is quite like cotton. It is the most important of all natural fibres, accounting for half of all the fibres used by the world's textile industry.
Cotton has many qualities that make it the best choice for countless uses:
Cotton fibres have a natural twist that makes them so suitable for spinning into a very strong yarn.
The ability of water to penetrate right to the core of the fibre makes it easy to remove dirt from the cotton garments, and creases are easily removed by ironing.
Cotton fabric is soft and comfortable to wear close to skin because of its good moisture absorption qualities.
Charges of static electricity do not build up readily on the clothes.
Nobody seems to know exactly when people first began to use cotton, but there is evidence that it was cultivated in India and Pakistan and in Mexico and Peru 5000 years ago. In these two widely separated parts of the world, cotton must have grown wild. Then people learned to cultivate cotton plants in their fields.
In Europe, wool was the only fiber used to make clothing. Then from the Far East came tales of plants that grew "wool". Traders claimed that cotton was the wool of tiny animals called Scythian lambs, that grew on the stalks of a plant. The stalks, each with a lamb as its flower, were said to bend over so the small sheep could graze on the grass around the plant. These fantastic stories were shown to be untrue when Arabs brought the cotton plant to Spain in Middle Ages.
In the fourteenth century cotton was grown in Mediterranean countries and shipped from there to mills in the Netherlands in western Europe for spinning and weaving. Until the mid eighteenth century, cotton was not manufactured in England, because the wool manufacturers there did not want it to compete with their own product. They had managed to pass a law in 1720 making the manufacture or sale of cotton cloth illegal. When the law was finally repealed in 1736, cotton mills grew in number. In the United States though, cotton mills could not be established, as the English would not allow any of the machinery to leave the country because they feared the colonies would compete with them. But a man named Samuel Slater, who had worked in a mill in England, was able to build an American cotton mill from memory in 1790.

Vanessa atalanta
Family: Brush-footed Butterflies(Nymphalidae)
Subfamily: True Brushfoots (Nymphalinae)
Identification: Upperside is black with white spots near the apex; forewing with red median band, hindwing with red marginal band. The winter form is smaller and duller, summer form larger and brighter with an interrupted forewing band.
Life history: The Red Admiral has a very erratic, rapid flight. Males perch, on ridgetops if available, in the afternoon to wait for females, who lay eggs singly on the tops of host plant leaves. Young caterpillars eat and live within a shelter of folded leaves; older caterpillars make a nest of leaves tied together with silk. Adults hibernate.
Flight: Two broods from March-October in the north, winters from October-March in South Texas.
Wing span: 1 3/4 - 3 inches (4.5 - 7.6 cm).
Caterpillar hosts: Plants of the nettle family (Urticaceae) including stinging nettle (Urtica dioica), tall wild nettle (U. gracilis), wood nettle (Laportea canadensis), false nettle (Boehmeria cylindrica), pellitory (Parietoria pennsylvanica), mamaki (Pipturus albidus), and possibly hops (Humulus).
Adult food: Red Admirals prefer sap flows on trees, fermenting fruit, and bird droppings; visiting flowers only when these are not available. Then they will nectar at common milkweed, red clover, aster, and alfalfa, among others.
Habitat: Moist woods, yards, parks, marshes, seeps, moist fields. During migrations, the Red Admiral is found in almost any habitat from tundra to subtropics.
Range: Guatemala north through Mexico and the United States to northern Canada; Hawaii, some Caribbean Islands, New Zealand, Europe, Northern Africa, Asia. Cannot survive coldest winters; most of North America must be recolonized each spring by southern migrants.

Blue Hole at Red Clay State Park
Red Clay State Historic Park is located in the extreme southwest corner of Bradley County in Tennessee, just above the Tennessee-Georgia state line.
The park encompasses 263-acres of narrow valleys formerly used as cotton and pasture land. There are also forested ridges that average 200 feet or more above the valley floor. The site contains a natural landmark, the Blue Hole Spring, which arises from beneath a limestone ledge to form a deep pool that flows into Mill Creek, a tributary of the Conasauga and Coosa River system. The spring was used by the Cherokee for their water supply during council meetings.
