Nikola Tesla, Esq.,
Colorado Springs, Colo.

Dear Mr. Tesla:

Two dozen O. K. dry batteries, large size, and two dozen small size, have been expressed to-day. The clockwork will be ready for shipment to-morrow, Friday.

Great improvement, Mr. Uhlman says, has been made in the pump, the same giving a steady, solid stream without splashing, the speed of the second break has been increased and work on the third break is progressing rapidly.

Respectfully,
Geo. Scherff
