This stamp appears to have been originally stamped upon the buff envelopes common at the time, and to have been cut out and fastened to the letter. No further information concerning it has yet been discovered. The files at Washington, of the Alexandria Gazette, the only Alexandria paper of that period, are defective from May 22nd, to October, 1845, and in part for 1847. Daniel Brien was Postmaster at Alexandria during 1845-47. X. STAMPS OF THE BALTIMORE POSTMASTER. This stamp was first chronicled in the Philatelical Journal in 1874. The copy there described was the only one known, until very recently, a second copy was described in the New York World, and subsequently that and another were mentioned in the Alexandria Gazette, of August 3rd, 1886, as having been in possession of Mr. Thomas Semmes, of Alexandria. These are described as postmarked respectively, January 15th, and 31st., 1847, with the other marks usual upon letters of the period. From 1845 to 1849, Mr. James Madison Buchannan was the postmaster at Baltimore, and is said to have issued this stamp in the fall of 1846. Further details are wanting. The stamp is a simple looking slip of paper containing the signature of the postmaster in fac-simile, in one line, and the value, "_5 Cents_," in a second line, bordered by a frame of single colored lines, crossed at the four angles. Impression, 55 by 15 mm., in color upon thin bluish paper. 5 cents, black. [Illustration: James M. Buchannan (handwritten signature) PAID 5 (with 5 inside circle)] Besides these adhesive stamps, Mr. Buchannan also issued a species of franked envelope. Two copies of this were found by Mr. Robt. H. Smith, in examining his old letters. They are the ordinary buff wove envelopes of the period, size 80 by 137 mm., of the old simple form with straight edged flaps. In the right upper hand corner the signature "James M. Buchannan," hand stamped, 50½ mm. long, the "B," 4½ mm. high. Beneath this in a second line the word "PAID," in capitals, 4 mm. high, and 16 mm. long is also hand stamped. Below this again, a large numeral "5," 11½ mm. high, in an oval 20½ mm. long by 7½ high, is also hand stamped. The specimen described is hand stamped with the ordinary round hand stamp of Baltimore, Md., and dated Nov. 24th, no year stated and is directed to the present owner and finder. Impression hand stamped in blue ink on buff envelopes. 5 cents, blue. Besides these it has been claimed that the stamp known as the "horseman," was also issued in 1860 or 1861, by the Postmaster of Baltimore. It may be described as a rough design of a horseman, galloping to the right, holding a streamer, inscribed: "_One Cent_." On ribbons above, "_Government City Dispatch_." Rough frame of vertical lines with rough ornaments in the corners, bordered by a single colored line. Impression, 23 by 17 mm., apparently lithographed in color on white paper.
