Change in appropriation—Under a decision of the Comptroller 
of the Treasury, the appropriation for the fiscal year, hereto-

SUMMARY REPORT 
CLASSIFICATION OF THE OPERATIONS 
As set forth in the introductory paragraphs of this report, 
the operations in the Bureau of American Ethnology relate to 
the essentially human or demotic characteristics of the peoples 
under investigation, i. e., the American aborigines. These 
qualities, as displayed by mankind in general, constitute the 
object-matter of five sciences, namely, (1) esthetology, (2) tech- 
nology, (3) sociology, (4) philology, and (5) sophiology. So far as 
practicable, all of these sciences have been cultivated with 
equal assiduity, although administrative conditions have led to 
the arrangement of the work along special lines, in such 
manner as to produce the best results from the work of the 
collaborators. 
EXPLORATION 
During the earlier portion of the fiscal year Mr Cosmos 
Mindeleff was occupied in extending and completing his explo- 
rations and surveys in southwestern United States. During 
the field season of 1894 his operations were largely confined 
to Canyon de Chelly in northeastern Arizona, but his recon- 
noissances and surveys were extended into contiguous territory. 
During July and the earlier part of August he examined San 
Juan valley and there obtained information of much interest. 
In its topography and general geographic conditions this region 
appears to have been well adapted to the needs of the ancient 
pueblo builders, and it affords examples of nearly all the types 
of aboriginal villages now known, together with other types
