Dr. J. Van Tyne,

University of Michigan, 
Ann Arbor, Michigan. 
Dear Van Tyne: 
I am a little slow in answering your kind 
invitation of April 24 as 1 have had to hold off briefly until 
I could survey the horizon for other commitments. The only 
thing at the moment is a meeting of the Ldtin American 
Committee on Guggenheim fellowships that is to come the 
middle of June, for which the date is not yet fully established. 
I have, also, to appear some time before a Senate Committee on 
Appropriations but that may not be until later. 
I looked into.the matter of travel and find that 
I can leave Washington by air in the evening, cutting across 
by non-stop flight to Detroit in two hours. This would bring 
me there in ample time to get the night train for Roscommon. 
What I would like to do would be to leave here Thursday evening, 
reach Roscommon early Friday morning and remain there until 
Tuesday or Wednesday following. The actual weekend I would 
need to establish a little later on. 
In the meantime, I am asking the Fish and 
Wildlife Service to extend my Federal permit to take migratory 
birds to include the State of Michigan, and will appreciate very 
much if you will take up the matter of the Michigan permit. 
My present Federal permit is #7861 issued October 12, 1950, 
expiring December 31, 1954. Any specimens that I take would 
be placed in the U. S. National Museum collection. If the request 
is not too embarrassing, I would like to ask permission for not 
to exceed three Kiftland warblers which would be prepared as 
skeletons and placed in the National Museum skeleton collection. 
It would be very useful to have representation of this species in 
that form. We have a fair series of skins.
