Sept. 1. 1807.
To any, whom it may concern.
At the very earnest solicitation of Mr. John Frizell, of Walpole (Mass.) whose name is mentioned in the inclosed, I state, that, according to the best of my knowledge, he has sustained the character of an industrious, honest citizen, without any uncommon advantages in learning; that he is now a poor man, as to interest; that he has made a number of useful inventions, or at least, improvements in mechanism; that the one herein described, was first published in my paper, from which it was copied into others in the United States; but the successful effects of which I am quite ignorant of; and that he, as far as in these respects, he may be deemed useful to the public, may justly be entitled to their approbation and encouragement.
