Mr. Clarence H. Knowlton,

Hingham, Massachusetts. 
Dear Mr. Knowlton* 
We are greatly indebted to you for the early letter of Professor 
Fernald. There are always too fm of such letters available after a 
man passes away, particularly in his own hand writing. This letter 
will be placed in our historical file for future reference of people 
interested. 
Cordially yours. 
RCRsc 
Reed C. Rollins.
