Note II'-24 — Chapter II · ITINERARY, CONTINUED: THROUGH OLD MEXICO, IN CHIHUAHUA, DURANGO, AND COAHUILA, TO THE PRESIDIO GRANDE, MARCH 22D-MAY 31ST, 1807.

La Cadena is present name of a place on or near the fourth one of the small streams above noted, considerably off (?) the modern main road—say 20 m. S. W. of Peronal, and 25 m. due W. of Mapimi. It is reached by a rough mountain road 18 m. from Pelayo, past the copper mine of Oruilla; the hacienda there, of which Pike speaks as being so rich in stock, had been deserted when Wislizenus passed in 1847. The creek comes from the Sierra de las Mimbres, on the W. Another steep range rises about 3 m. E. of La Cadena; the gap between the two is the Pass of Cadena, Puerta de Cadena, or "Door of the Prison," through which Pike goes to-day due E. in the direction of Mapimi.
