LETTER OF TRANSMITTAL, 



U. S. Department of Agriculture, 

 Division of Economic Ornithology and Mammalogy, 



Washington, D. C, April 14, 1888. 

 Sir : The investigations in economic ornithology and mammalogy 

 ordered by Congress to be made under your direction consist of two 

 separate inquiries, namely : (1) concerning the food habits of birds and 

 mammals in their relation to agriculture; and (2) concerning the migra- 

 tion and geographical distribution of North American species. 



It has been deemed best to publish the results of these investigations 

 in separate bulletins. In accordance with this decision I transmit here- 

 with, as Bulletin 1 of the Division of Economic Ornithology and Mam- 

 malogy, a report upon the English Sparrow in North America, by Wal- 

 ter B. Barrows, assistant ornithologist. 

 Respectfully, 



0. Hart Merriam, 



Ornithologist. 

 Hon. Norman J. Oolman, 



Commissioner of Agriculture.
