Our Great Travelers. Birds that fly from pole to pole and shun 
the darkness: Birds that make 2,500 miles in a single flight. By 
Wells W. Cooke, of the Biological Survey, U. ‘S. Department of 
Agriculture. Reprinted from the National Geographic Magazine, 
April, 1911.

for more intimate study than the open field affords. It should 
also aid in the preservation from destruction of some of our 
weaker and less adaptable species. Le ds
