_August 31._--At daylight we commenced repairing damages. I found that by taking out one of the standards to the top of the carriage, and wrapping that and a piece of broken whiffle tree tightly with raw hides soaked soft in water, the coach promised well for a temporary purpose with a light weight. To lighten us I left on the road our agent for the Pimos station whom I had with me, also the two men who were to return to Tucson with the mail. I then proceeded on my journey towards San Diego. Camped about 12 o’clock on the banks of the Gila river. Made 40 miles to-day. _September 1._--Off at daylight this morning; reached the first village of the Pimos about sunrise, and there I bought the corn necessary for our mules, a little wheat for same purpose, and a few beans, also a pair of chickens. (Wheat should be fed sparingly, and soaked before using.) Our barter consisted of cotton cloth and a few bells, both of which I purchased in Tucson. Camped for breakfast at the Maricopa wells, which we have since selected as the site for our station; remained at the wells until 3 p. m. waiting for our agent to come up whom I yesterday left behind on the road. Finally he came along, and we prepared for a start. While camping at the wells I was witness to the largest Indian battle of the times. The Yuma Indians, aided by the Mojaves and Tonto Apaches as their allies, attacked the Maricopas just before daylight this morning. The Maricopas and Pimos are allied strongly together. The former being comparatively few in numbers, are rather under the protection of the more numerous Pimos. The Maricopas are the more western of the two tribes, and as the Yumas approached from down the river, their villages were consequently the first attacked. Some warriors and their families were killed, and their huts fired before the presence of the Yumas was known. We saw the huts blazing and thought they were signal fires. Besides warriors on foot, every Indian that could get a horse was in the fight, many of them going a half dozen miles to reach the battle ground. One aged chief, whose wife had been killed by the Yumas, rode furiously up to our camp, foaming at the mouth, and begged of us in good Spanish to aid them against the Yumas; of course we declined. When the battle was over he refused to speak or understand a word of Spanish. The principal fight was along the bank of the Gila, not half a mile from our camp. One hundred and four Yumas left their villages at the junction of the Gila and Colorado, led on by a young and ambitious chief, whose new dignity required some striking act to dazzle his people. He and ninety-three of his warriors were killed within an half hour, on the side of a hill in plain view from the spot where I was reclining under a tree.
