One word on mount and equipment. The horse is a light chestnut--sorrel we call it here--about fifteen hands high, compact and active, with flowing mane and tail. He cost a hundred dollars six months back; in England, for a park hack, he would be worth three fourths as many pounds. He has four paces--a walk of about four miles an hour, a jog-trot of five, a lope or canter of six or seven, and a regular gallop. He passes from one pace to another by a mere pressure of the leg against his sides, and the gentlest movement of the reins. To turn him, be it ever so short, carry the bridle-hand toward the side you want to go, but put away all notion of pulling one rein or the other. He will walk unconcernedly through the deepest mud or the quickest flowing brook, and climb a steep hill with hardly quickened breath; if he meets a big log in the trail, he will just lift his fore-legs over it and follow with his hind-legs without touching it, and hardly moving you in the saddle. And he will carry a twelve-stone man, with a saddle weighing nearly twenty pounds, and a pack of fifteen pounds behind the saddle, from eight in the morning till six in the evening, with an hour's rest in the middle of the day, and be ready to do it again to-morrow, and the next day, and the day after that. The saddle is in the Mexican shape, with a high pommel in front, handy for a rope or gun-sling, and a high cantle behind; it has a deep, smooth seat, and a leather flap behind and attached to the cantle on which the pack rests; huge wooden stirrups, broad enough to give full support to the foot, and wide enough for the foot to slip easily in and out. A horse-hair belt, six inches wide, with an iron ring at each end, through which runs a buckskin strap to attach it to the saddle, and by which it is drawn tight, forms a "sinch," the substitute for girths. The word "sinch" is a good one, and has passed into slang. If your enemy has injured you and you propose to return the compliment in the reverse of Christian fashion, "I'll sinch him," say you. If a poor player has won the first trick by accident, "I guess he'll get sinched soon," says the looker-on. I advise no Englishman to bring saddlery to Oregon. He will save no money by doing so, and will not be fitted out so well for the hours-long rides he will have. I have only heard one Englishman out of fifty say that he prefers the English saddle, after getting used to the Mexican, and he had brought one out with him and used it out of pride. Behind the saddle is the pack. Just a clean flannel shirt and a pair of socks, a hair-brush, a comb and tooth-brush, fit us out for a week or two; baggage becomes truly "impedimenta" when you have to carry it on your horse. You need not carry blankets now, for there are good stopping-houses at fit distances apart. But you may, if you wish, bring your Martini carbine, or Winchester rifle, for we may meet a deer by the way. So we start.
