For such a work, however, the late Mr. Jenyns, the well- 

 known brother-in-law of Professor Henslow, and Vicar of 

 S waff ham Bulbeck, in Cambridgeshire, for nearly thirty

 Washington in 1886, to which welcome assistance has 

 been given by the publications of the Biological Survey. 

 The Forest, Fish, and Game Commission of New York 

 State has begun to issue a regular Report, in which it calls 

 the attention of every citizen to his duties towards the 

 Birds and, conversely, to the various duties which they
