Mr. Walter Deane,

 Cambridge, Mass. 



Dear Sir : 



In regard to your inquiries about base elevations used 

 by various cities and the United States Government in this sec- 

 tion, would say that I have looked the matter up and find that 

 the best information on the subject is contained in report of 

 John R. Freeman on the proposed Charles River Basin. 



As there are none of these reports available for dis- 

 tribution I am unable to send you one, but if you wish to call 

 at this office I will be willing to loan you my own copy. 



Very truly yours. 



Engineer.
