67. Butler on the Effects of Civilization. 



[ludiana: A Century of Changes in the Aspects of Nature. By 

 A. W. Butler. Proc. Indiana Ac. Sci. v. p. 31.] 



Mr. Butler sends us a copy of his Presidential Address to 

 the Indiana Academy of Science delivered at Indianopolis in 

 December last. It treats in an interesting and impressive 

 way of the changes wrought in the State of Indiana by the 

 hand of the white man. In the beginning of this century 

 the greater part of the State was one primeval forest of 

 enormous trees, interspersed with meadows and prairie. 

 These were tenanted by bisons in countless numbers, 

 wapitis, deer, and other large mammals. Among the birds. 

 Turkeys, Colins, Ruffed Grouse, and Paroquets were abun- 

 dant. Passenger Pigeons existed in millions. Now the 

 great trees are gone, and the birds have perished with them, 

 through the destructive energy of ^'civilized man." '' Except 

 in a few localities " there remains " no virgin forest," and 

 as regards birds, a set of new-comers, adapted to the change 

 of environment, has replaced the Paroquet and the Passenger 

 Pigeon in the secondary Avoods and shrubs.
