from four to eight rooms on the ground floor. The entire district is
richly studded with mounds. On an excursion three or four miles down
Piedras Verdes River I saw several groups of mounds, some of which,
no doubt, contained many objects of antiquity. On top of one low hill
was a large group, and half a mile north of this another, 160 paces
long and containing two oblong mounds. Some of the mounds were ten
or twelve feet high.

A very trustworthy Mormon informed me that there were no ruins,
in caves or otherwise, along the river between this settlement and
Colonia Juarez; nor were there any, he said, for a hundred miles south
of Pacheco, though mounds could be seen in several places. Therefore
when I at last departed from Cave Valley, I took his advice and did
not follow the course of the Piedras Verdes River down to San Diego,
but led the pack train the safer, though longer, way over the regular
road. The country along the river was afterward explored by members of
my expedition. They came upon several small caves high up on the side
of the cañon, some of which had once been inhabited, to judge from the
many potsherds and the smoky roofs; but no cave-houses were found until
higher up the river, where some were seen in the sandstone cliffs.

I broke camp in Cave Valley on March 11th, and arrived on the same
day at Old Juarez, a few miles from my camp at San Diego. Now the
weather was warm; the grass was sprouting, and I noticed a flock of
wild geese going northward.

The plains of San Diego used to swarm with antelopes, and even at
the time of my visit herds of them could be seen now and then. One
old hunter near Casas Grandes resorted to an ingenious device for
decoying them. He disguised himself as an antelope, by means of a
