June 12th, 1899 letter from Nikola Tesla to George Scherff

Colorado Springs, June 12, 1899

Dear Mr. Scherff,

Inclosed check for shop expense and Telephone Comp.

I am very sorry to tell you that Willie has turned out very badly and compelled to send him away. Do not receive him when he comes. Both Mr. Loewenstein and myself were deeply astonished to discover his character.

Push all work as much as possible, and keep me well informed.

Yours sincerely,
N. Tesla
