In the northwestern part of the State of Chihuahua are found many interest- 
ing remains of antiquity. These remains are to be found lying near the village

known as the " Casas Grandes " in ihe language of the country, exist in the 
neighborhood, built of adobes and square timber. They are two and three stories 
high with a gallery of wood and stairway from the exterior. They have very 
small rooms and narrow doors in the upper stories, but are without means of 
entrance in the lower. A great watch tower, commanding an extensive prospect, 
stands on an elevation two leagues southwest of it. A series of mounds, contain- 
ing earthen vessels, weapons, instruments of stone, and fragments of white, blue 
and violet-colored pottery, extend along the banks of the Casas Grandes and
