I prescribe the horn saddle because of its convenience. One may sling upon it a camera, binoculars or other articles in frequent demand, and when it becomes necessary to lead a pack pony the lead rope may be attached to it. For this latter purpose the horn is indeed indispensable.
In the light of personal experience with both single and double cinch saddles, I recommend the latter unhesitatingly, particularly for mountain work. In steep ascents or descents it will not slide, while a single cinch saddle is certain to do so no matter how tightly cinched, and this shifting will sooner or later gall the horse's back. In Mexico the single cinch saddle is almost universally used, but who ever saw a Mexican's horse that was free from saddle sores? The forward cinch should preferably be a hair cinch, though the ordinary webbed sort, both forward and rear, does well enough.
The saddle blanket should be a thick, good quality wool blanket. In Arizona Navajo saddle blankets are popular, and they are undoubtedly the best when obtainable. A hair saddle pad or corona, shaped to the animal's back and used in connection with the blanket, is a pretty good insurance against galling, and preferable to the felt pad, for it is cooler.
A leather boot for rifle, and saddle bags for toilet articles, note books and odds and ends, bridle, halter rope, a pair of cowboy spurs with large blunt rowels, and a quirt to tickle delinquent pack horses will be needed. The rifle boot has two sling straps. The usual method of carrying it is to insert it between the stirrup leathers on the near side, drop the sling strap at the top of the boot over the saddle pommel and buckle the sling strap at the bottom of the boot into the rear latigo ring. By detaching the latter sling from the boot before buckling it to the ring, the boot may be removed from or attached to the saddle by simply lifting the forward sling strap over the pommel, without unbuckling. In case the sling strap at the top of the boot be placed too far down, it should be shifted higher up and secured to the boot with a leather loop which may be riveted to the boot.

For the pack animals the ordinary cross-tree or sawbuck pack saddle is the most practical pack saddle for all-around use, though the aparejo, used by the army and generally throughout Mexico, is superior to the sawbuck when unwieldy packages of irregular size and shape are to be transported. Such packages must frequently be transported by army trains and they are the rule rather than the exception in Mexico, where freighting throughout wide regions must be done wholly on the backs of animals.
