My dear Dr. Schmitt: 
Mr, Tolson is away so I am replying for him to your recent 
letter asking some assistance for Colonel Whelen. We have gone 
through our picture files and are sending him a number of shots, 
some of which we hope will be useful for his trailways article. 
We are happy to be of service to him and to you. 
Sincerely yours.
