thirty species, collected in northern India. Professor Walter W. 

 Tupper, of the Department of Botany, University of Michigan, 

 Ann Arbor, Michigan, furnished several microscopic slides of tropical 

 woods for study purposes. 



For the exhibit of osage orange installed in Charles F. Millspaugh 

 Hall (Hall 26) Mr. Hermann C. Benke, of Chicago, donated several 

 negatives and prints of the tree in summer and winter condition; 

 the Von Platen-Fox Company, of Iron Mountain, Michigan, 

 furnished a board of tamarack; and Mr. 0. G. Moore of Brownsboro, 

 Alabama, donated a sample of chittam wood. For use in conjunction 

 with the exhibits of American woods the Museum obtained, through 

 the efforts of Professor Emanuel Fritz, of the University of California 

 at Berkeley, California, cone-bearing branches of several Pacific 

 Coast species, viz. redwood, incense cedar, western red cedar, Port 

 Orford cedar and Monterey cypress. 



Through the generosity of Mr. W. E. Bletsch, of Highland Park, 

 an Associate Member of the Museum, the services of several men 

 were furnished for cutting a large number of North American woods 

 into hand specimens of a size suitable for distribution among scientific 

 institutions and forestry schools. These woods were not needed for 

 exhibition purposes, and had been kept in storage for a number of 

 years. 



The Department distributed through exchanges 1,038 herbarium 

 specimens and photographs to fifteen institutions and individuals 

 in North and South America, Europe, India, and Australia. Thirty- 

 six lots of plants were lent for study to various institutions, and 

 sixty-four lots were received on loan, for study or determination.
