REPORT OP THE SECRETARY. 35 



the United States, many specimens being suitable for exhibition and 

 no less than 49 are sufficiently well preserved to be identified specifi- 

 cally. Other well-preserved turtles acquired included the type of a 

 box turtle described by Dr. O. P. Hay, and an example from the 

 Cretaceous of Georgia, valuable chiefly on account of its locality. 



Fossil bones of the mammoth, rhinoceros, and horse collected for 

 the Museum in Siberia by Mr. John Koren to supplement the ma- 

 terial obtained by the Koren expedition in 1914-15, included a beau- 

 tifully perfect mammoth humerus over 3 feet in length, indicating 

 an animal of magnificent proportions. 



Type material comprised the important additions in paleobotany. 

 Fossil plants from Wyoming, the basis of a paper by Dr. F. H. 

 Knowlton, were transferred from the survey; two lots from South 

 America were contributed by Prof. E. W. Berry, the first from the 

 Tertiary rocks of Bolivia, valuable not only as type specimens, but in 

 furnishing data for additions to the geologic history of that country, 

 the second from the Miocene of Peru; and specimens from Beaver 

 County, Okla., described by Prof. Berry, were donated at his re- 

 quest by Prof. E. C. Case. 



Textiles. — The efforts of domestic manufacturers to take advan- 

 tage of the opportunity afforded by the war is shown by upholstery 

 velvets and velours manufactured in this country from mercerized 

 cotton, mohair, or silk, or combinations of these, including antique 

 Venetians made of mercerized cotton in imitation of old French and 

 Italian fabrics and intended to take their place at a reasonable price. 



The silk goods series was augmented by new figured novelty silk 

 representing beautiful effects in the cross-dyeing of combinations of 

 cotton, wool, artificial silk and spun silk, brocaded piece-dyed satins, 

 figured cross-dyed crepe georgette, crepe meteore, and fabrics printed 

 in designs suggesting water movements, silk poplins, georgette crepe 

 printed in spiderweb-like design called "camouflage," and suggest- 

 ing Japanese batik work, " Mcon-Glo " crepe, a novelty crepe weave 

 fabric with metalliclike surface, and a rough surface fabric printed 

 with an all-over oriental design. 



Fine silk fabrics ornamented with attractive designs by means of 

 discharge printing are believed to be among the best examples of this 

 method of printing fabrics that have been produced in the United 

 States. These included Luxor taffeta, in Persian, Saracenic, and 

 Italian designs of the eighth, thirteenth, and fourteenth centuries, 

 copies from ancient Peruvian fabrics, and Wedgwood prints which 

 carry out remarkably the relief effect copied from Wedgwood 

 pottery. 



Woolen fabrics of the worsted type, woven from combed wools, are 

 well represented in the Museum collections, but the carded woolen 

 industry has not been adequately covered heretofore. Particularly
