RC (MHi); at head of text: “Thomas Jefferson Esqr”; endorsed by TJ as received 3 June 1812 and so recorded in SJL. Enclosure: Abraham Howard Quincy’s undated advertisement entitled “Fire Stone Wanted,” 95 Broad Street, Boston, stating that he has invented stone stoves that save “90 per cent. of the usual expense of both fuel and labor, and entirely reduces the hazard from fire”; that his holdings of the necessary stone on the Connecticut River would suffice to supply the entire United States; that he wishes nonetheless to be advised of the whereabouts of other deposits so that he can establish local stove manufactories; that he thinks this cotton- or soapstone “(soft and free from grit)” is widely dispersed; that the stoves will reduce from six months to two days the time it takes for a man and team to supply enough wood for a year to a family keeping two fires; that the stoves are powerful enough for all sorts of public spaces, applicable to all sorts of cookery, and use entirely new principles; and adding that he operates “An extensive Manufactory of Inkstands, Slate Pencils, Foot-Stoves, Furnaces, Oven, and other Fire-Doors, Boiling, Refining, and Cooling Kettles, and Vats for Sulphur, Salts and Salt-Petre, &c. all of stone, under Patents,” and that as “the sole Inventor of Stone Stoves” he will prosecute those who infringe his patent (printed broadside in ViW: TC-JP).
