INDEX TO PAPERS RELATING TO FOOD OF BIRDS. 21 



ANNUAL REPORTS. 



Each of the Annual Reports of the Department of Agriculture 

 consists of the report of the Secretary of Agriculture together with 

 those of the chiefs of the various bureaus and divisions. Only the 

 reports of the Chief of the Bureau of Biological Survey and of its 

 predecessor, the Division of Ornithology and Mammalogy, are of 

 interest in the present connection. The first report deals with eco- 

 nomic investigations carried on from July 1, 1885, to February 20, 

 1887, a period of more than one and a half years. All subsequent 

 reports cover approximately a period of one year. 



Up to and including the Report for 1893, original articles corre- 

 sponding to those now published in the Yearbook, and written by 

 various members of the division, accompanied the reports of the 

 chief. Seventeen of them appeared in the eight reports specified. 

 Beginning with that for 1894 the reports of the chief are of a more 

 routine character, containing the customary review of the year's 

 work, plans for the succeeding year, and recommendations. Fre- 

 quently, however, specific references to bird food are made and all of 

 these are indexed. The comment on each report in the following 

 bibliography gives an idea of the subjects more generally treated.
