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.
