REPORT OF NATIONAL MUSEUM, 1922. 93 



1921, on " Homekraft weaving," by Mrs. Anna Knott Shook, of New 

 York City, the Museum was presented with one of the hand-operated 

 portable looms invented and used by Mrs. Shook and 14 beautiful 

 examples of woven articles formed directly on the loom according 

 to her system. These articles represent a departure from the 

 ordinary hand weaving and include useful household articles and 

 wearing apparel. 



While the widespread revival of hand-knitted garments, such as 

 socks, sweaters, and caps, which marked the period of the World War 

 has somewhat subsided, since there is no longer a need to knit such 

 garments for soldiers, it is still true that hand knitting continues to 

 be very popular, and there has been even an increase in the demand 

 for fancy SAveaters, scarfs, etc. To meet this demand for novelty 

 effects in hand-knitted garments, manufacturers of worsted knitting 

 and crocheting yarns have been producing many new kinds of yarn 

 for this purpose. S. B. & B. W. Fleisher (Inc.), of Philadelphia, 

 Pa., contributed for exhibition examples of these new yarns and a 

 series of hand-knitted garments illustrating their use, which are to 

 replace the extensive series of specimens presented by them in 1919. 



Specimens of cotton fabrics collected in Java, decorated by the 

 wax-resist process known as " batik," whereby a design is first traced 

 on the undyed fabric by means of a fine stream of melted wax, and 

 a "tjanting," one of the small copper implements for melting and 

 pouring the wax, were purchased to illustrate this beautiful and 

 popular method of decorating fabrics. 



Standard commercial grades of the most important cordage fibers 

 were received through the generous cooperation of Wiggles worth & 

 Co. (Ltd.), of London, England, the firm which handles the greater 

 part of America's imports of these raw fibers. 



A two-spindle flax-spinning Avheel for spinning and winding two 

 threads at one time was presented by William H. Beach, of Seneca 

 Falls, N. Y. 



A hand-operated knitting machine, capable of knitting stockings, 

 scarfs, etc., was contributed by Mr. E. L. Sechrist, of Washington, 

 D. C, for inclusion in the Museum's series of models and machines 

 arranged to illustrate the principles of knitted structures. 



In the division of medicine the most important accession of the 

 year was a series of charts prepared and contributed by the H. K. 

 Mulford Co., of Philadelphia, Pa., comprising 91 specimens, photo- 

 graphs, and labels so arranged as to tell the story of the prevention 

 and cure of certain diseases by means of biological medicines; also 

 a series of 15 large colored transparencies and two bromide enlarge- 

 ments of photographs which illustrate some of the principal proc- 

 esses and tests used in the manufacture of these medicines by methods 

 approved by the Government. These charts show the vaccine treat-
