of the Caroline Islands, and devoted a month in Luzon in connection 

 with the Robert P. Cummings 1 Philippine Expedition. Returning 

 home from the Philippines via China and Japan and the Hawaiian 

 Islands, he visited on the way Canton and Peking. As a result of 

 this expedition the Museum has received about 80 cases of material 

 and several hundred photographs. 



The Assistant in Dendrology has completed two periods of field 

 work on North American Forest Trees, during the past year, his Spring 

 work being completed in southern Missouri and begun in West Vir- 

 ginia, and his Autumn work completed in West Virginia. As a result 

 a large amount of valuable material has been added to last season's 

 accumulation which is now curing in preparation for installation. 

 There was also secured, in addition to the timber specimens, a val- 

 uable series of tree photographs, fruit and herbarium specimens, as 

 well as accessory material for the systematic collections of the Depart- 

 ment in general. The Curator has made two extended trips to the 

 museums of Europe, visiting Ireland, Scotland, England, Holland, 

 Germany, Austria, Italy, Sicily, Switzerland, France, and Belgium. 

 Resulting from this work is an extensive series of photographs, ex- 

 haustive notes on museum technique, and valuable comparisons and 

 studies made of type species. Mr. O. E. Lansing, Jr. has continued his 

 field work in the Lake Chicago Basin during the past season, adding 

 largely to the series of plants already secured to represent this van- 

 ishing flora. 



Early in June about ten days were spent by the Curator of 

 Geology in the newly discovered diamond fields in Pike county, 

 Arkansas. All the important outcrops of the diamond-bearing perido- 

 tite were visited and specimens obtained. In addition the gypsum 

 and asphalt beds in the vicinity were visited and specimens of their 

 products collected. The Assistant Curator of Paleontology in the 

 latter part of the season, with two assistants, spent about two 

 months continuing in eastern Wyoming the collection of Loup Fork 

 Miocene fossils. Most of the work was done in the vicinity of Raw 

 Hide Buttes, Wyoming, and a considerable amount of important 

 material was obtained. Among this were some excellent skulls of 

 the rare form Moropus, a nearly complete skeleton of Procamelus, 

 some rhinoceros skulls, and specimens of Miocene horses. Collecting 

 of Cretaceous and Tertiary invertebrate fossils was carried on by the 

 Assistant Curator of Invertebrate Paleontology in Mississippi during 

 April and May. The principal Cretaceous collections were made
