There are relics of ornaments found in caves of early man, and, as before mentioned, relics of paints. The clothing of early man can be conjectured by the implements with which he was accustomed to dress the skins of animals. Among living tribes the bark of trees represents the lowest form of clothing. In Brazil there is found what is known as the "shirt tree," which provides covering for the body. When a man wants a new garment he pulls the bark from a tree of a suitable size, making a complete girdle. This he soaks and beats until it is soft, and, cutting holes for the arms, dons his tailor-made garment. In some countries, particularly India, aprons are made of leaves. But the garment made of the skins of animals is the most universal among living savage and barbarous tribes, even after the latter have learned to spin and weave fabrics. The tanning of skins is carried on with a great deal of skill, and rich and expensive garments are worn by the wealthier members of savage tribes. The making of garments from threads, strings, or fibres was an art discovered a little later. At first rude aprons were woven from long strips of bark. The South Sea Islanders made short gowns of plaited rushes, and the New Zealanders wore rude garments from strings made of native flax. These early products were made by the process of working the fibres by hand into a string or thread. The use of a simple spindle, composed of a stone like a large button, with a stick run through a hole in the centre, facilitated the making of thread and the construction of rude looms. It was but a step from these to the spinning-wheels and looms of the Middle Ages. When the Spaniards discovered the Pueblo Indians, they were wearing garments of their own weaving from cotton and wood fibres. Strong cords attached to the limbs of trees and to a piece of wood on the ground formed the framework of the loom, and the native sat down to weave the garment. With slight improvements on this old style, the Navajos continue to weave their celebrated blankets. What an effort it must have cost, what a necessity must have crowded man to have compelled him to resort to this method of procuring clothing! {99} The artistic taste in dress has always accompanied the development of the useful, although dress has always been used more or less for ornament, and taste has changed by slow degrees. The primitive races everywhere delighted in bright colors, and in most instances these border on the grotesque in arrangement and combination. But many people not far advanced in barbarism have colors artistically arranged and dress with considerable skill. Ornaments change in the progress of civilization from coarse, ungainly shells, pieces of wood, or bits of metal, to more finely wrought articles of gold and silver.
