EXHIBIT AT PAN-AMERICAN EXPOSITION. 185 



specimens of the conglomerate rock of that Locality. Mr. Adolph 

 Tuchband, who made an expedition to the Upper Amazon River in the 

 spring' of 1900, undertook to obtain ethnological objects, models, cos- 

 tumes, utensils, etc. of the Indian tribes of that region. The Museum, 

 however, received nothing from this source. 



Mr. \Y J McGee, ethnologist in charge, Bureau of American Eth- 

 nology, was granted a small sum to collect objects illustrating the 

 ethnology of the Tepoka Indians of Mexico. On visiting their country, 

 however, he found the tribe practically exterminated, and he turned 

 his attention to the Cocopa Indians, from whom he obtained a valuable 

 collection. 



Additions to the various series which it was decided to exhibit were 

 also made by purchase from professional collectors and dealers both 

 in the United States and Europe. 



Prof. J. B. Steere spent two months on the Amazon River in obtain- 

 ing characteristic fishes and other vertebrates of that part of South 

 America and objects illustrating- the ethnology of the various Indian 

 tribes. Messrs. Barton A. Bean and W. H. King were detailed to go 

 to Key West, Florida, to collect fishes in formalin, for a special exhibit, 

 to which further reference will be found on page 186. 



THE EXHIBIT OF THE DEPARTMENT OF BIOLOGY. 



By Frederick W. True, 

 Head ( 'urator. 



In planning an exhibit from the Department of Biology many points 

 have to be taken into consideration, such as the letter and spirit of 

 the law providing for a Government exhibit; the purpose of the expo 

 sition as a whole; the conditions existing as regards obtaining speci- 

 mens suitable for exhibition; the relative significance and attractive 

 ness of different exhibits to the general public. 



In the case of the Pan-American Exposition the underlying idea 

 was so (dearly defined that no difficulty was experienced in determin- 

 ing the proper scope of the exhibit. The Exposition, as its name 

 implies, was intended to represent Americaas a whole. It was lining. 

 therefore, that the animals and plants of North. South, and Central 

 America should be represented, while a representation of the fauna 

 and flora of the rest of the world could with propriety be omitted. 



The exhibit of the Department was thus limited and only American 

 objects were represented. From experience gained by participation 

 in other expositions it was fell that, generally apeaking, large objects 

 would be more suitable and better appreciated than small ones, and it 

 was decided, therefore, to confine the zoological exhibit to the verte- 

 brates. There is no question that a representation of the invertebrate
