 tribution for this species and that only the fixed type was able 

 to migrate.

CORRESPONDENCE. 



The Editor, The Ottawa Naturalist. 



Mr. P. A. Taverner's "Suggestions for Ornithological Work 

 in Canada," strike the right note. At present we Canadian bird 

 lovers are more in touch with Washington, D.C., than with our 

 own Ottawa. Only a few of us even know each other. By the 

 formation of an Audubon Society in Winnipeg recently an 

 attempt has been made to bring bird observers together. Hardly 

 anyone in the West outside a limited circle is aware of the 

 splendid original work of Norman Criddle and his brother Stuart. 

 Probably none of your readers have the least idea that in A. G. 

 Lawrence, of Winnipeg, and H. E. Pittman, of Wauchope, Sask., 

 there are some rising lights in nature lore, especially in ornitho- 

 logy. I could name a few qthers, old and young, who might 

 be linked together for the purposes suggested by Mr. Taverner. 

 As a writer of sorts and as a lecturer on our birds I am impresse d 

 by the unused material lurking in Manitoba alone.
