[D8847AAQ], Letter from Thomas Commerford Martin to Thomas Alva Edison, May 31st, 1888

Editor's Notes

"I have been greatly interested in looking over an advance copy of the June 'North American Review' containing your article on the perfected phonograph. The uses you there enumerate recall to my mind one that suggested itself not long since, and which, perhaps, you may deem worthy at some time of trial. The idea I had was to utilise the phonograph as a watchman's register. It could of course be cheaply made for such work, and there would be, what no system has yet ensured, the absolute proof that the man on duty had actually made his round himself and visited the machine. A special pass word might be given him for each night at starting. I think the scheme is practical. ### My only excuse for troubling you is that I greatly prize my associations with the phonograph in days gone by, and would gladly do anything to aid in its development and employment. [TAE marginalia: "Write + say I have dreamed of the use suggested it’s a fine idea + would form the basis of a good watchman system. Will suggest further about it."]
