SYMPOSIUM ON SCIENCE AND RECONSTRUCTION 61 



north Greenland Eskimo, embracing weapons of the chase, 

 wearing apparel, domestic implements, games, toys, etc. 

 This collection, contrasted with a somewhat similar one 

 from Point Barrow, Alaska, represents quite well the dif- 

 ference in the cnltnres of the two groups of Eskimo repre- 

 sented by these regions. From this northland the expedi- 

 tion also brought back enough musk-oxen, caribou, polar 

 beai-s, blue foxes, and other smaller mammals as well as 

 birds, to make a very instructive exhibition of the fauna 

 of this Arctic region. 



Of insects the museum possesses the great Bolter collec- 

 tion containing upwards of 100.000 specimens of insects 

 from many parts of the world, but particularly representa- 

 tive of Xorth American species. Stored in the Physics 

 Building are many fine specimens of corals, echinoderms, 

 mollusks. and other invertebrates, from many parts of the 

 world, but chiefly American, which aggi-egate 50.000 speci- 

 mens. These include an almost complete series of theUnion- 

 idae or fresh water mussels of our rivers obtained by that 

 veteran collector. Mr. A. A. Hinkley. In addition there are 

 several thousand fossils from American formations. It is 

 not making too large an estimate to state that the Univer- 

 sity Musetim possesses at the present time about 200.000 

 specimens as a nucleus with which to build tip a modern 

 Xatural History Museum. 



To fidhll its ideal function the museum must be devel- 

 oped along two quite distinct lines. First, the exhibit 

 series, which may be made of educational value to many 

 departments in the University. This series shoidd contain 

 synoptic collections of both living and extinct animals and 

 plants : evolution series showing the development of many 

 forms of life through past geological periods : series illtis- 

 trating correlation of structure with function : geogi'aphic 

 distribution series: habitat groups showing the ecological 

 relation of animals and plants to their environment ; show- 

 ing the relation of natural objects to agriculture, industry, 

 and commerce ; series showing the geological history of the 

 planet upon which we live, including the minerals and 

 ores obtained from the rocks : and many other topics which 

 can be treated by the exhibition method. 



The second line of development is the study or research 

 series. This should include large series of specimens. — 

 animals, plants, fossils, minerals, etc., — which may be
