Lamb's textile industry of the United States, embracing biographical sketches of prominment men and a historical résumé of the progress of textile manufacture from the earliest records to the present time; . special mechanism has been introduced to overcome this defect,and by constantly changing the ratio produced a more uniform distributionof the coils. Previous to Hill & Browns Patent the friction or drum type of ma-chine was constructed with the thread guide some distance from the sur- 112 TEXTILE INDUSTRIES face of the cop and reciprocated by special mechanism. The Hill & Browninvention departed from this structure and introduced an angular slot inthe drum, extending from N to M, through which the yarn was threaded,thus operating as a cam to force the yarn from end to end of the traverseat each evolution of the drum. Machines constructed upon this principlehave been widely used in mill practice, as a much higher yarn speed wassecured than by structures using the reciprocating guide. Their use hasbeen largely confined to Great Britain and the continent of Europe, as themill requirements in the United States are such that the machines have notmet with a ready introduction OF THE UNITED STATES 113 THE HISTORY OF WEAVING. The art by which threads or yarns of any substance are interlaced soas to form a continuous web is perhaps the most ancient of the manufactur-ing arts, since clothing must always have been a primal necessity to knowledge of weaving seems to have been inherent to a slight extent inall races, and to have developed as they emerged from savagery, beginningwith the plaiting of rushes or other fibrous materials into mats and aprons,followed by rudely woven cloths. A piece of flaxen cloth, plaited ratherthan woven, was found in the lake dwellings of Switzerland, which is sup-posed to have been made by prehistoric man in the Stone Age; and invarious ethnographical museums may be found specimens of the handiworkof peoples who lived in those p
