[NEW JERSEY PENNSYLVANIA]. STEVENS, Thaddeus (1792-1868), Radical Republican Congressman. Autograph letter signed ("Thaddeus Stevens") to John Cadwalader, Lancaster, [PA], 16 September 1849. 1 page, 4to, integral address leaf. Stevens informs Cadwalader, an important Philadelphia lawyer, of a situation, possibly a legal case, involving iron production: "We have only proved the quantity of ore taken since 1845 ranging from 3100 to 4300 tons; we could not prove the quantity...before the change in the blast...We proved however that the hot blast consumed one half more ore than the cold blast." Stevens was a leading abolitionist politician before the Civil War and a champion of Radical Reconstruction after the war's conclusion. -- [AMERICAN REVOLUTION]. GORDON, D. Loyalist Merchant. Autograph letter signed ("D Gordon") to W. Powell, Philadelphia, 24 January 1778. 2½ pages, folio. A letter which discusses the dilemmas facing loyalist merchants in the midst of the Revolutionary War. Writing from Philadelphia, only recently occupied by the British, Gordon laments about a market in which "a Musquet [sic] would be much more suitable for the ladies...than Embroidered Gowns." Noting how the market follows the fortunes of war, Gordon complains about, "the small spot of Ground we are yet able to call our own in this Country," but acknowledges that, "if by large reinforcements from home We are able to extend our Conquests, & of course our Commerce, you shall see me writing in a very different mood." He comments on threats to Loyalists: "The Rebels have threatened burning our shipping, & if they can our Houses during the winter." Gordon notes the success of the last campaign, pointing out that "Deserters come in daily in Tens & Twentys...[but] whom we may still venture to call rebels." -- [AMERICAN REVOLUTION] Dunlap's Pennsylvania Packet or The General Advertiser, Vol. III, no. 139 (Monday, 20 June 1774). 4 pages, folio.
