scene of his operations, and there I was soon confirmed in my suspicions that this plausible pamphlet was built on a falsehood, and that the patrons whom M^' Rumsey's address has procured him in this city, have committed themselves too unreservedly to a stranger. I now find the reason of his so long delaying to put in his claim -- it was that a period might elapse sufficient for memory to be uncertain, and for facts to be transposed in the order of time; the death of one of his principal workmen also rendered it probable that some of his pretended proofs might be difficult to detect. A love of justice has induced a number of persons to step forward and testify in the most unequivocal manner that the works sworn by M"" Rumsey's evidences to have been finished the first December, 1785, were not begun until March following, when he must have been very fully possessed of a knowledge of my pretensions.

The ten following certificates will fully prove the antedating.

N°. 14.
