Killingworth, Nov. 22d, 1775
[Extract]
Sir, ー I have to ask pardon for the wrong information I gave you. At the time of my last writing, I supposed the Machine was gone, but since find one proving the navigation of it in Connecticut River. The forcing pump made by Mr. Doolittle, not being made according to order given, did not answer; which has delayed him.2 The trials I mentioned to have been made since Dr. Franklin's being here,3 was the explosion, which prov'd beyond expectation.
I suppose he sets off this day with his new constructed pump, in order to prove the navigation, and if not prevented by ice in the River, will proceed soon. So far as you may have made known the contents of my letter, you may add this supplement.
He is by no means discouraged in the attempt. I had not seen him myself since Dr. Franklin was here, as his movement I had only from common report, but have since seen him myself. But few know the cause of his present delay.
