Title
[D8732ABD], Letter from John H Vail to Thomas Alva Edison, August 18th, 1887
Editor's Notes
"Is there any possible method whereby we can arrange to dispose of the feeder equalizers in our central stations. ## The cost of these equalizers in stations of modern size is about $250. per feeder, and in stations like New York, Philadelphia and Chicago, they will be between $800. and $850. per feeder. This runs up the expense to between $7000. and $12000. on these large stations. ## In addition thereto, a great deal of valuable space is occuppied by the feeder equalizers which are very cumbersome and unsightly. ## I thought that perhaps you might have some method in mind which would enable us to overcome this difficulty, and at the same time, preserve careful equalization of pressure."
