 lost an efficient and appreciated ally. 



In the year 1861 the late Henry A. Ward, then professor of geology in 

 the University of Rochester, erected on the college campus a building 

 which he called Cosmos Hall and which was devoted to the assemblage 

 and preparation of scientific material for museums of natural history.

 ishes. Its work was performed largely by young men of congenial tastes, 

 who there acquired the practical experience which commended them later 

 to the trustees of larger responsibilities. It thus served incidentally as a 

 training school in the natural sciences and especially in certain branches 

 connected with museums. Among its graduates are Freileric A. Lucas,
