August 7th, 1899 letter from Nikola Tesla to George Scherff

Colorado Springs, Aug. 7, 1899 

My dear Mr. Scherff,

Many things to write you about but not a moment to spare.

A heavy cold right now makes correspondence still more difficult. Under inclosure check for the larger items total $529.11. Please pay small bills to save trouble of writing checks.

I am satisfied with my progress.

Yours sincerely,
N. Tesla

P. S. Do as you like about the Gas Co. affair. I do not know anything about it.
