The only particular in which I could not commend and adopt the native practice was the Mexican bit. It is a dreadful instrument of torture, putting immense leverage in the rider's hands, and enabling him at will to tear the mouth of his horse to pieces; indeed, the horse on which it is used is guided entirely by pressure on the opposite side of the neck from that in which one seeks to turn him. Our Eastern way of drawing his head around would so lift the bit as to drive him frantic. There are very few horses of any breed, even the Mustang, that _never_ stumble; and as I prefer lifting my horse to letting him break his knees or neck, I want a bridle I can pull upon without tearing his mouth. So, in spite of its handsome appearance and the very manageable single white cord into which its two reins are braided, I eschewed the Mexican head-gear, and took the ordinary Eastern snaffle and curb. Immense spurs completed our accoutrement,--whips being here unknown. I may as well make a word-map of our route before going farther. Pilgrims to the Yo-Semite ship themselves and their horses from San Francisco by steamer to Stockton. This town is on the San Joaquin, the most northerly of a series of rivers fed directly from the Sierra Nevada water-shed, and here through the middle portion of the State,--a series, indeed, continued through much of the still lower Pacific coast to the Isthmus of Nicaragua. The Sacramento drains quite a different region, that of the broad plains between the Sierra and Coast ranges, occupying the northern portion of the State,--resembling in its physical features, much more than any of the Pacific streams beside, the large isolated trunks which drain the east slope of the Alleghanies. The Colorado is almost the only other large river created from many tributaries, which debouches between the Columbia and the Isthmus,--and that rises east of the mathematical axis of the Rocky Mountains. The Yo-Semite valley is one of the cradles through which the short Sierra-draining rivers reach the ocean; its threading stream is the Merced; and if on any good United-States Survey-map you will please to follow that river back to the mountains, when your finger-nail touches the Sierra it will be (or would, were the maps somewhat correcter) in the Great Yo-Semite. You will then see that our course led us across three streams, after leaving the San Joaquin at Stockton _en route_ for Mariposa,--the Stanislaus, the Tuolomne, and the Main Merced. The distance from Stockton to Mariposa is about one hundred miles, a small part of the way between fenced ranches, a much greater part on wide, open, rolling plains, somewhat like those of Nebraska, embraced between the two great ranges of the State. Here and there you find an isolated herdsman or a small settlement dropped down in this not unfruitful waste, and thrice you come to a hybrid town, with a Spanish _plaza_, and Yankee notions sold around it.
