IJr, Alex Wetmore, 
Corinne, Utah. 
Dear Isir. Wetmore: 
Your letter of June 1 was received yesterday. 
I would not pay much attention to the cattle pasturing 
controversy, but from time to time make an examination to see 
whether they are in any way damaging the breeding grounds of 
waterfowl. 
It is rather strange that the northern Phalaropes should 
stay so late, The packages which you name, I believe, have all 
arrived. 
Under separate cover, I am sending you an extra lens for use 
in close work. Mr. Kent says that you will have to experiment to 
find the focal length. You may do this by securing a sharp image 
on a piece of paraffin paper placed between the two rolls. 
With kind regards, I am. 
Very truly yours.
