Abstract

Col. Gouraud has shown me your leter of may 31 in answer to our criticism upon the last machines received here, which clearly shows you think we are not getting out of the instruments all they are capable of. I am sending you by this mail four records to show what results we are obtaining & I hope they will arrive safely & that you will give them you attention. ## The new phonograph is a most marvellous talker, more astounding than anything I ever heard and the greater part of our trouble is traceable to the BATTERY. One cell is not strong enough to insure governing when required to do the maximum work, hence irregularity & raise of pitch when reproducing; but by first shaving off the chaulk & afterwards letting recording needle down alone & making record it is PERFECT. Glad to learn you are sending battery which will give longer life & more power. ## I am quite as much at home with the adjustments of the new machine as on the former. ## Our first experience with people entirely unaccustomed or familiar with the phonograph--the repeating diaphragm certainly did pop off pretty lively; but [now?], I am glad to say, they all are getting satisfactory results every day in the office, doing regular business upon them. ## If y ou could spare me a few lines of comment upon these records I am sending, it would be a great favor.
