Dear Mr. Deane: 



I ivas glad to learn fron your letter of L^r 26 that 

 the worlc wMch you v;ish done on the salt narsla deposit had been 

 satisfactorily provided for by Prof. Pernald and Ms assistants. 

 I thm^it it probable that joxi would be able to interest Prof. Fer^ 

 nald in the test which you desired and I think ;rou will find 

 Llr. Reed a very active and interested investigator of the problem 

 which you Imve put beforo him. Ilr. Heed worked under n^r direction 

 for the Bureau of liines one sutaner saao years ago and did very sa- 

 tisfactory work. I shall be glad when tlie work is completed to 

 get a copy of v/hatever results are obtained by tiie investigation. 



Sincerely yours.
