in parks and gardens for ornamental purposes. They are arranged in
circles or in rectangles. I saw two circles close to each other, each
six feet in diameter. One rectangle measured fifty feet in length
by half that in width. Low walls divided it into three indistinct
partitions. There was never any wall built underneath these surface
stones, nor were there any traces of charring. Among the ruins found
on top of the hills we collected a lot of broken pottery and some
flint arrowheads. In several places in this district we found gold
and coal, but not in paying quantities.

Some forty miles south of Cochuta we turned in a southerly direction,
ascending a hilly plateau 3,200 feet above sea-level. Here we observed
the first orchids, yellow in colour and deliciously fragrant, and in
the cañon below we met the first palms. The rocks continued to show
volcanic and metamorphic formation.

About 130 miles south of Bisbee we caught the first glimpse of the
Sierra Madre rising above the foot-hills, some forty miles off
to the east. Its lofty mountain peaks basking in the clear blue
ether, beckoned to us inspiringly and raised our expectations of
success. This, then, was the region we were to explore! Little did I
