Ky dear Collins: 
Thank you very much for the opportunity to read more about the 
asbestos region of Somerset County. Later on I shall get at Prof. 
Warren and find out particularly whether the veins occur in surface 
ledges so that a characteristic vegetation might be expected, or whether, 
as in some of the Quebec aread, they are merely mines well underground 
andlcovered by glacial deposits. 
Sincerely yours.
