A preliminary enumeration of the birds on many farms of the United States, made during the summer of 1914, was so satisfactory and the information obtained so important that it was decided to repeat the work in 1915. In the second effort it was planned to cover as many different kinds of country as possible and particu- larly to secure more records and more reliable data concerning birds in the Gulf States and in the region from the Plains westward. The returns from the 1915 bird count were on the whole very satis- factory. As in 1914, the largest number of reports from any single section came from the Northeastern States^that is, the States north of North Carolina and east of Kansas—^but they are particularly gratifying because of their close agreement with returns of 1914 from the same section. When an enumeration of birds was first suggested the project was the subject of much good-natured banter and some criticism from those who declared the scheme utterly visionary. 1 Shortly after writing this report, and following a very brief illness, Professor Cooke died, March 30, 1916. He was a prominent ornithologist and the foremost American authority on the migration of birds.—Editor. Note.—This second report on the number and relative abundance of wild birds (see Dept.
