 ear Mr. leopold;- 
 
                   I am chagrined at seeing how long your letter 
 
of May 25th has remained unanswered. 
 
      My opinion that Hungarian Partridge and Sharp-tailed 
 
Grouse were incompatable was more the result of a hunch  than 
 
definite investigation, but I have seen nothing as yet to 
 
seriously modify my views. My data if not scientifically detailed 
 
and I have not been out west for a number of years to make 
 
personal observations. My information is all more or less indef- 
 
inite and loose . In many localities the Oharp-tail has come 
 
back more or less from the last low point but I have yet to 
 
hear of any place where the Hungarian Partridge is established 
 
that the Sharp-tailed high is at all comparable with the highs 
 
of previous times. The species onrnits upward cycle has come 
 
back but not as strongly as it should. This is eaactly as would 
 
be expected were the species antagonistic. Until some tollerance 
 
can be built up between them , a possible but doubtful eventualty,
