    Description

    Ironclad Inventor John Ericsson: Autographed Letter Signed. John Ericsson ALS, 2p. (front and back of a single 5" x 8" sheet), September 24, 1859. The entire letter is given over to a discussion of experiments dealing with circulating pumps. In part: "I have just returned from the Oliver boat where I have been to set the canes and test the circulating pumps. I am happy to say that my apprehension that the resistance offered by passing the oil through the one hundred wire discs might prove too great, is quite removed..." Quite clear and legible. In excellent condition save for an orange mark at the top of page one.
