2 volumes. xxii, 506; xvii, [1], 624 pp. Illustrated with 16 lithographed plates after Bartlett including folding frontispieces with tissue guards; numerous wood engravings; large folding map in Vol. I. (8vo) 22x14 cm. (9x5½"), full calf, gilt-lettered morocco spine labels. First Edition.

Important first-hand account of the survey which laid down the southwestern border between the United States and Mexico following the conclusion of hostilities. Jenkins calls this work "the most scholarly and scientific description of southwest Texas of its era," although Graff points out that "a number of incidents described by Bartlett have been differently interpreted by his associates." As delineated by Howes, "only one geyser pl, not two as listed, is found in v.2, that deficiency being made up by an unlisted view of Tucson."
