every stage of which is shown from the opening of the bale to a 
finished garment. The accompanying large exhibition of plain, 
piece-dyed, yarn-dyed, and printed cotton fabrics includes not only 
standard goods like sheetings, drills, cambrics, percales, organdies, 
chambrays, ginghams, double-faced napped goods, cotton flannels, 
etc., but also dress goods novelties like crépes and ratines. 
The wool industry is inaugurated by a series of raw wools repre- 
senting the best classes raised in this country, and for comparison 
a few selected fleeces from other parts of the world. Other speci- 
mens show the injurious effects of poor pasturage and disease upon 
the quality of the material and the trouble and expense caused 
the manufacturer by improper methods of marking sheep and 
sorting and baling wool. The very different processes employed in 
the manufacture of woolen and worsted goods are brought out in 
three large series of specimens, one showing the successive steps in 
the production of a woolen overcoat fabric, another of worsted yarn 
by the French system, and a third by the Bradford or English sys- 
tem. The general collection which follows comprises suitings, broad- 
cloth, cheviots, serges, diagonals, dress goods, crépes, voiles, challies, 
cashmeres, Panama cloth, bunting, cloakings, etc., examples of 2 
yards or more of each being draped in an effective manner to bring 
out the particular qualities of each fabric. 
The silk section commences with a case devoted to the natural 
history of the cultivated mulberry silkworm, and includes besides 
eggs, worms, chrysalises, cocoons and moths, large models of a silk- 
worm and of the male and female moths. <A second. case contains a 
series of commercial raw silks from the principal markets, together 
with specimens showing the methods of wrapping, marking, tying, 
and conditioning them. In still other cases are illustrated thrown 
silk and the processes used in preparing silk threads for weaving, 
sewing, and embroidering, as well as the utilization of silk waste 
from the steam filatures and of the cocoons from which moths have 
emerged. The exhibit of silk fabrics, which is extensive, is arranged 
according to the methods of dyeing and finishing rather than to use, 
and comprises piece-dyed, skein-dyed, printed, and brocaded goods, 
besides silk velvets and plushes. At the southern end of the hall is 
a fine display of color work on silk, which includes skein dyeing, 
illustrated by two rows of skeins of thrown silk in 150 shades, piece 
dyeing, and both warp and surface printing of silk goods by copper 
rollers. In other cases the subjects of textile printing and orna- 
mentation of fabrics by figure weaving are also presented. 
A large and deep wall case along the eastern side of the hall is 
devoted to the historical aspect of the industry, and contains several 
machines and models of machines which mark important epochs in
