              Mr. Aldo Leopold, 
                Madison, Wisconson 
 
 
              Dear Mr. Leopold: 
 
                      Recently the Department of Conservation of Michigan
asked me 
              for a statement of my qualifications for filling a certian
position 
              which theywill have to fill soon. I would be glad to have Mr.
Lovejoy 
              see a copy of the recent preliminary report I made on the project
I 
              am at present engaged in and as you have the only copy of this
report 
              that is available for circulation I should be very glad if
you would 
              forward it to him at an early date. If you have not as yet
had time 
              to look over this report you may request Mr. Lovejoy to return
it to 
              you. 
 
                      The data on antelope, sheep, deer and buffalo which
you request 
              is enclosed., You understand of course that during the two
yearly mig- 
              rations the average and maximum daily travel is much greater
for all 
              species of mamnals which subsist on grass and other forage
plants. 
 
                                            Very truly yours, 
 
 
 
                                                 W. 1. Rush
