There were in the country we passed over, some beautiful mountain meadows and most luxuriant forests, and some of the sloping table lands looked like the ornamental parks of an extensive domain. These oak-clad tables and ridges, were the harvest fields of the San Joaquin Indians, and in their vicinity we found an occasional group of deserted huts. These, with their adjacent supplies of acorns, were at once given to the flames. The acorns found and destroyed by the scouting parties, were variously estimated at from eight hundred to one thousand bushels; beside the supply of Piñon pine-nuts and other supplies hoarded for future use. The pine-nuts were not all destroyed by fire; most of them were confiscated, and served as a dessert to many a roast. From the total amount of acorns estimated to have been destroyed, their supplies were comparatively small, or the number of Indians on the San Joaquin had been, as in other localities, vastly overrated. Our search was thoroughly made--the explorations from day to day, extending from our camps over the whole country to an altitude above the growth of the oaks. During these expeditions, not an Indian was seen after those noticed on the upper San Joaquin; but fresh signs were often discovered and followed, only to be traced to the rocky cañons above where, like deceptive “_ignes fatui_,” they disappeared. Being allowed the largest liberty as surgeon to the expedition, I had ample time to examine the various things found in their camps, and obtain from Sandino all the information I could concerning them. The stone arrow-heads and their manufacture, especially interested me. I found considerable quantities of the crude material from which they were made, with many other articles brought from other localities, such as resin, feathers, skins, pumice-stone, salt, etc., used in the manufacture of their implements of war, and for the chase as well as for domestic uses.
