In the eastern section of mound _V_, Mr. Dent has, as I was informed and saw, dug down one metre into the dark loamy clay and stones of which the knoll is composed, and has thus exposed a small stone chamber, or flue, walled in to the north, west, and south in the ordinary manner, and closed with earth, etc., at the east. Whether there was any stone top other than rocks heaped up above the hillock I could not learn; neither did I, in digging down further, find any floor. This chimney-like structure is 1.32 m.--3 ft. 8 in.--wide from E. to W., and 0.70 m.--2 ft. 3 in.--from N. to S. It is therefore too large for a chimney, or flue, and too small for a room. Out of it Mr. Dent, whom I could not find personally, as he was absent at the time, extracted a human skeleton and much fairly preserved pottery. Of course, I was unable to see what he carried off (among which was the skull), but I saw and dug further in the same excavation, removing out of it bone splinters and the best preserved pottery piece of the entire collection. They are, in part, very similar to the yellow bowls still made by the Indian pueblo of Nambé (a Tehua tribe); but many of them have been so charred and blackened that it is impossible to make out their color. The pottery is all thin. Among it were also bits of charcoal and of rotten wood. The structure therefore appears to have been a grave, in which the body was placed in a sitting posture with its face to the east. Subsequent information and discovery have fully confirmed this view. I shall return to this on a subsequent page, and only state here that my efforts to find another skeleton in the same location failed. The aboriginal remains encircled by the great wall of circumvallation and north of the old church are now exhausted, so far as my work among them goes, and the surroundings of the _mesilla_ shall therefore become the subject of report. The slope towards the east and south-east is rocky on the top, covered with sandy soil growing _grama_ and very few cedar bushes, studded with ant-hills, and devoid of all remains of human structures so far as I could see. Pottery and obsidian are ever present, but become perceptibly less and almost disappear further east. The rills which drain the eastern slope carry much of this broken stuff into a small arroyo that winds to the left of the _mesilla_. About one quarter of a mile east of the building _A_, on a bare sunny and grassy level, are, quite alone, the foundations of a singular ruin. They run N. and S., consist of three rows of stones laid aside of each other longitudinally, and have the shape shown in Pl. V., Fig. 10.
