Barns went to Baltimore shortly a.ter to have some machinery cast ; and on his return from Baltimore was sent to Frederick-town in order to have some other things made (which could not consistently with Governor Johnson's letter bo earlier than the beginning ot November) and about the middle of November they were all finished viz. a holier^ two cylinders^ 'jmmps, pipes, Sfc. -- I confess this is very brisk work for a country town -- more than ever I could get in the city of Philadelphia.

At Baltimore four large cocks were bespoke by IVR Barns and tlie brass founder was told they were for the warm spi'ings of Virginia as will presently appear; Governor Johnson was entrusted with the scheme in confidence, and copper- works were carried on in Frederick-town with great secresy -- inasmuch that a citizen hearing it rumoured that they were for a Steam-engine, applied to see them, but was refused (as will be shown) and the matter still remained a secret until, as Governor Johnson says, "The designed purpose of the cylinder was a subject of pretty general conversation in Frederick-town" -- Then during this interval of privacy, surely any man that should have conceived the same idea and brought it forward to pubhc view, ought to be entitled to the right and advantages of the discovery -- for all these confidential persons, as I have already said, might have died and the world have lost the benefit -- Let me consider the danger of admitting this new doctrine sf claims -- A man makes a valuable discovery -- he pursues it at a jreat expense and publishes it to the world -- a set of men com- Tming together shall afterwards come forth, swear for each other, liat they had been making the same kind of engine, many months )efore, and bring proofs from respectable characters, that they had Ainted at the practicability of such a scheme, even before their private experiments.
