Remarkable Ant-hill.
Passing Cochuta about a hundred miles south of Bisbee, we came upon a deposit of fossils. It was scarcely more than a mile in extent, but many bones were said to have been taken away from it as curiosities. I had already observed isolated fossil bones along the creeks on several occasions during our travels, but we could find nothing here of value.
Signs that the country was in former times occupied by another race than its present inhabitants are seen everywhere throughout the region we traversed following the road to the south. Here they appear frequently as remarkable groupings of stones firmly embedded in the ground. Only the tops of the stones (the total length of which is about one foot) are seen above the surface, much as stones are used 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 think then that it would shelter me for several years. It looked so near and was yet so far, and as we travelled on southward the sight of it was soon lost again.
We gradually descended to the Bavispe River, a name here given to the Yaqui River, in accordance with the custom which the Mexicans have in common with people in other parts of the world of giving different names to one river in its course through different districts. It was a treat to catch the first sight of the magnificent sheet of water the river forms near the town of Opoto, as it slowly wends its way through green shrubs. It is the largest river of the west coast of Mexico and is here about 1,400 feet above the level of the sea.
Following the river to the south, we soon passed the towns of Guasavas and Granados. The vegetation along the river banks is in strong contrast to the land in general. Here are fields of sugar-cane, and in the orchards, orange, fig, and lime trees grow in abundance. The country, though fertile, is dry, and the heat is great. Even at the end of October the thermometer sometimes registered 100° F. in the shade. The grass had become dry and scarce, and it was difficult to keep the animals in satisfactory condition.
