tolerated by the casual observer who wished to get the most 

 enjoyment with the least effort from bird study. But we are 

 not concerned about that class of people. It seems to us that 

 a species cannot well be more than abundant, and that there- 

 fore the qualifying adjective " very " might well be omitted. 

 Before any such scheme can be put into practical use it needs 

 to be carefully tested by a series of field studies by two persons 

 working side by side, the one counting the birds and tabulat- 

 ing the results according to this scheme, the other taking notes 

 upon the general impression made by the numbers, but count- 

 ing the individuals seen to be avoided. That is to say, the 

 scheme should be, as far as possible, shorn of its arbitrariness 

 by making it as natural as possible. The result would proba- 

 bly be that different values would be given to the large birds 

 than to the small ones. Thus, five Bald Eagles to the mile 

 would be abundant, while that number of Vesper Sparrows to 

 the mile would be only common. Dr. Wolcott is to be highly 

 commended for his efforts to bring about uniformity in the 

 field work of ornithologists. — L. J.
