Title
[LB025050A], Letter from Thomas Alva Edison to Colin D Anderson, August 9th, 1887
Editor's Notes
I have your letter of the 1st instant in reference to a new vacuum process. I have tried a great many of these pumps without any success, and have decided that the method which I employ is the best. It does not take ten hours to create a vacuum as you state, but only one hour, and I believe that I can obtain as much work from my system as from any in the market.
