Reading edition
Mr Leroux also reported to Bartlett the existence in the Verde valley of heaps of débris like those on the Salado. Bartlett's Pers. Nar., vol. ii., p. 247. Mention of Verde remains. Warden, Recherches, p. 79; Möllhausen, Reisen in die Felsengeb., tom. ii., pp. 140-2; Mühlenpfordt, Mejico, tom. ii., pt. ii., p. 538. Pike, Explor. Trav., p. 336, says very absurdly, "Those walls are of a black cement which encreases in stability with age, and bids defiance to the war of time; the secret of its composition is now entirely lost."
