 been comparatively little new installation in any one of the depart- 

 ments. The resources of the Department of Anthropology are taxed 

 to the uttermost to take care of the constantly increasing amount of 

 material which is acquired. The Curator estimates that at the close 

 of this year there will be on hand sufficient material to fill at least five 

 exhibition halls. The scientific arrangement of the department, owing 

 to the lack of floor space, is no longer possible, and the idea of the 

 scientific geographical arrangement must necessarily be abandoned, and 

 future arrangement, therefore, in the present building, will be largely 

 a matter of convenience. Halls 6 and 7 have been overhauled and are 

 now ready for exhibition purposes. The Curator of Geology reports 

 the most extensive rearrangement undertaken was that of Hall 68, 

 where are exhibited clays, soils, etc. As the collection of clays 

 especially had become large and of considerable technical value, a 

 classification was needed by which the collection could be dis- 

 played so as to be of general interest. After a study of various 

 classifications, one proposed by Prof. Edward Orton, Jr., was adopted, 

 and the collection rearranged on that basis. The series includes, 

 first, a synoptic collection illustrating varieties of clays and their rela- 

 tions and origins. The classification is indicated in the case by a series
