tions of plain, ratine, and mercerized cotton yarns, with spun silk 
and viscose silk in plain and fancy weaves; plain, piece-dyed and 
yarn-dyed dress goods of all cotton and cotton and artificial silk; 
cotton fabrics finished to imitate those of silk and of wool and fancy 
printed cotton velvets in gold and silver effects for millinery pur- 
poses. The collection of wool and woolen products was enriched by 
a large assortment of new fleeces of the best American and foreign 
wools, all carefully graded and labeled to show the value in the 
grease and when scoured; specimens marking the steps in the manu- 
facture of both woolen and worsted goods, and many pieces of fin- 
ished fabrics of both classes. The already extensive silk collection 
was enlarged by the addition of a commercial package of skeins of 
the finest Japanese raw silk, many yards of printed broad silks rep- 
resenting the latest seasonable designs, brocaded novelty silks for 
dress trimmings, and samples of ties, scarfs, veilings, and ribbons of 
all kinds. Another important acquisition was the oldest model of 
the Grant silk reel, now in universal use for winding silk into stand- 
ardized crossed skeins. The manufacture of fur felt hats from .the 
finest grades of beaver, nutria, hare, and coney furs was illustrated 
by a comprehensive collection showing each step in the process from 
the fur pelt to the finished hat, and including the leather and silk 
trimmings for the principal types of hats. The development of an 
artist’s plan for the decoration of a fabric by weaving or printing 
was represented by a series of preliminary sketches, weaver’s drafts, 
and engraved plates for use on the pantograph machine, all bearing 
on the technology of design. 
In the division of mineral technology, including a few of the 
exhibits presented at the St. Louis exposition of 1904, which had 
not previously been unpacked and recorded, the principal accessions 
of the year were as follows: A very full illustration of the processes 
of glass making; a complete working model of a bituminous colliery 
at Fairmont, W. Va., covering a space of 30 by 40 feet; a reproduc- 
tion of a bituminous mine at Willock, Pa., 8 by 12 feet square, which 
excellently supplements the former; a relief panel illustrating proc- 
esses involved in the manufacture of illuminating gas, tar, ammonia, 
and other coal products in what is known as the by-products coke 
industry ; a number of photographic enlargements depicting typical 
underground operations incidental to coal mining; a series of native 
gypsum and gypsum products; and a collection illustrating crude 
mica and its industrial products.

The most important acquisition consisted of the formal transfer to 
the Institution, by Mr. Charles L. Freer, of Detroit, Mich., of 198 ob- 
jects as additions to his munificent gift to the Nation, comprising the
