No class of articles of textile nature were more universally employed by the aborigines than mats of split cane, rushes, and reeds, and our information, derived from literature and from such remnants of the articles themselves as have been recovered from graves and caves, is quite full and satisfactory. Mats are not so varied in form and character as are baskets, but their uses were greatly diversified; they served for carpeting, seats, hangings, coverings, and wrappings, and they were extensively employed in permanent house construction, and for temporary or movable shelters. A few brief extracts will serve to indicate their use in various classes of construction by the tribes first encountered by the whites. Hariot says that the houses of the Virginia Indians-- Are made of small poles made fast at the tops in rounde forme after the maner as is vsed in many arbories in our gardens of England, in most townes couered with barkes, and in some with artificiall mattes made of long rushes; from the tops of the houses downe to the ground.[17] [Illustration: PL. I. PRODUCTS OF THE TEXTILE ART. _a_, Openwork fish baskets of Virginia Indians; _b_, manner of weaving; _c_, basket strainer; _d_, quiver of rushes; _e_, mat of rushes.] It would appear from a study of the numerous illustrations of houses given by this author that the mats so often referred to were identical in construction with those still in use among the tribes of the upper Mississippi and the far west. The rushes are laid close together side by side and bound together at long intervals by cords intertwined across. In _e_, plate I, is reproduced a small portion of a mat from Hariot's engraving of the dead-house of the Virginia Indians, which shows this method of construction. The modern use of mats of this class in house construction is known by an example which I have seen represented in a small photograph, taken about the year 1868, and representing a Chippewa village, situated somewhere in the upper Missouri valley, probably not far from Sioux City, Iowa. [Illustration: FIG. 2.--Use of mats in an Indian council (after Lafitau).] Mats were used not only in and about the dwellings of the aborigines, but it was a common practice to carry them from place to place to sleep on, or for use as seats or carpeting in meetings or councils of ceremonious nature. The latter use is illustrated in a number of the early accounts of the natives. Figure 2, copied from Lafitau, serves to indicate the common practice. The omnipresent sweat-house of the aborigines is thus described by Smith: Sometimes they are troubled with dropsies, swellings, aches, and such like diseases; for cure whereof they build a Stone in the forme of a Doue-house with mats, so close that a few coales therein covered with a pot, will make the patient sweat extreamely.[18]
