Dear Mr. Leopold: 
In your letter of April 16 you mention 
using the map on pheasant and Hun planting in a Joint 
article. The map is, of course, not finished, but 
perhaps far enough along to warrant using, if explained 
tiat additions and corrections are desired. I have no 
infornation from the State Departments of California, 
Oregon, Colorado, Georgia, Tennessee or Massachusetts, 
but may be able to get some of this by writing again. 
Wight has pointed out that the distribution 
of pheasants shown in the Rocky Uountain states is mis- 
leading, according to his experience. The map is un- 
questionably crude, but since it is based largely on 
reports from the State Departments I think it would be 
possible to use it as a tentative record, 
I am returning the mobility charts with the 
figures I have. 
Very truly yours,
