 agriculture. By F. E. L. Beal, B. S. 40 pp. 22 figs. May, 

 1897. 

 Eevised edition. 48 pp. 22 figs. March, 1904. 



The original edition (1897) contains summaries of the food habits of 28 

 species and brief references to the nature of the food of 8 others. The

 Farmers' Bulletin 54 is the one article on bird food to have if the complete 

 series of bulletins and other publications of the Biological Survey is inacces- 

 sible. Many of the food summaries, though brief, are important, being based 

 on the examination of large numbers of stomachs. Several of them, for in 

 stance those on the kingbird, cedar bird, robin, and bluebird, are the most com- 

 prehensive statements yet published on the economic relations of these common 

 and important birds.

 total of 595,000 copies has been distributed.
