his work on the monograph of the fossil sturftshes. A nionog-niph on 

 the fossil Ostracoda is in conteinpUition. 



Mr. Lucas is still engaged on the monograph of the Stegosauria 

 mention(Hl in my last report, and has also devoted some time to the 

 study of certain points in the structure of Hesperornis and Baptornis. 

 He has also studied a series of birds from the Pliocene of Oregon sub- 

 mitted b\' Prof. J. ('. Merriam. 



ASSISTAXCK TO I^■DIVIDUALS AND INSTITUTIONS. 



The usual custom of lending material for study has been followed, 

 as in previous years. Material from the divisions of Geology and 

 Mineralogy has thus been lent to the U. S. Geological Survey and ver- 

 tebrate material to Messrs. Osborn. Gidley, and Hay. of the American 

 Museum of Natural History in New York, and to Mr. .1. B. Hatcher, 

 of the Carnegie Museum at Pittsburg. Material from the Section of 

 Invcrte))rate Paleontology has l^een lent to Dr. John M. Clarke, of 

 Albany; Dr. C. E. Beecher, of New Haven; Mr. ,]. K. Duerden, of 

 Johns Hopkins University, and Miss Elvira Wood, of the Massachu- 

 setts Institute of Technology. The U. S. Geological Survey, as usual, 

 has had free access to the materials whenever occasion demanded. 



PLANS FOR THE FUTURE. 



The generalized section across th(^ entire American continent, which 

 was referred to in my last annual report, remains as yet untinished, 

 owing to lack of funds. The collection which was to accompaii}" the 

 same is also incomplete and remains in an old wall case entirely 

 unsuited for this use, but which, it is hoped, may shortly be replaced. 



It is expected that the skeleton remains of the Triceratops or Clao- 

 saurus will be mounted for exhibition dui'ing the coming 3'ear aiul, 

 possibly, also, that of the Mastodon ol)tained at Church. Michigan, in 

 the sununer of 1901. 



Furtlxu' development along lines other than those alread}^ estab- 

 lished is rendered practically impossible, owing to lack of space. 



It is extremely desirable, if not essential to the welfare of the 

 Museum, that the Department should l)e allowed to have an annual 

 allowance for Held and collecting exi)enses. No museum can rel}^ 

 wholly upon gifts for its advancement. Collections coming by this 

 means ai'c invariably lacking in certain essential materials which can 

 be Old}" in part supplied by purchase. Mon^ than that, the scientific 

 force can not, 1 believe, be kept up to the desired point of efficiency if 

 they are obliged to i-emain at their desks throughout the summer 

 months. 1 am strongly in favor of sending men into tlie tield when- 

 ever it is possible. At present thei'e are at least three I'egions capable 

 of furnishing desirai)le fossil in\ertebrates, which it is very essential 

 we should in\estigate at once, besides numerous localities for Axrte- 

 brate fossils, minerals, and general geological materials.
