January 22, 1891.
J. B. Newbrough, M. D.,
Shalam, Las Cruces, New Mexico.
Dear Sir:- 
Mr. Edison has received your note of 15th instant, in which you ask what will stop [echo?]. In reply he says that [echo?] is a very difficult thing to overcome, but that partitions or screens will obstruct the wave, and thick paper on the walls should improve matters.
Yours very truly,
A. O. Tate
Private Secretary.
