An invention so important to the agricultural interest (and, as it has proved, to every department of human industry) could not long remain a secret. The knowledge of it soon spread through the State, and so great was the excitement on the subject, that multitudes of persons came from all quarters of the State to see the machine; but it was not deemed safe to gratify their curiosity until the patent right had been secured. But so determined were some of the populace to possess this treasure, that neither law nor justice could restrain them; they broke open the building by night, and carried off the machine. In this way the public became possessed of the invention; and before Mr. Whitney could complete his model and secure his patent, a number of machines were in successful operation, constructed with some slight deviation from the original, with the hope of escaping the penalty for evading the patent right.
As soon as the copartnership of Miller and Whitney was formed, Mr. Whitney repaired to Connecticut, where, as far as possible, he was to perfect the machine, obtain a patent, and manufacture and ship to Georgia such a number of machines as would supply the demand.
Within three days after the conclusion of the copartnership, Mr. Whitney having set out for the North, Mr. Miller commenced his long correspondence relative to the cotton-gin. The first letter announces that encroachments upon their rights had already begun. "It will be necessary," says Mr. Miller, "to have a considerable number of gins made, to be in readiness to send out as soon as the patent is obtained, in order to satisfy the absolute demands, and make people's heads easy on the subject; _for I am informed of two other claimants for the honor of the invention of cotton-gins, in addition to those we knew before_."
On the 20th of June, 1793, Mr. Whitney presented his patent to Mr. Jefferson, then Secretary of State; but the prevalence of the yellow fever in Philadelphia (which was then the seat of government) prevented his concluding the business relative to the patent until several months afterwards. To prevent being anticipated, he took, however, the precaution to make oath to the invention before the notary public of the city of New Haven, which he did on the 28th of October of the same year.
