I had the lead. Up on the mesa we struck into a trot. A lope is easier to ride, but the trot is the natural gait of a horse, and he can keep up a trot longer than he can a lope. Horses prefer trotting to galloping.

Trot, trot, trot, we went.

"How you coming?" I asked, to encourage Van.

"All right," he grunted. "These stirrups are too long, though. I can't get any purchase."

"Doesn't your instep touch, when you stand up in them?"

"If I straighten out my legs. I'm riding on my toes. That's the way I was taught. I like to have my knees crooked so I can grip with them. Don't you, yours?"

"Just to change off to, as a rest. But cowboys and other people who ride all day stick their feet through the stirrup to the heel, and ride on their instep. A crooked leg gives a fellow a cramp in the knee, after a while. Out here we ride straight up and down, so we are almost standing in the stirrups all the time. That's the cowboy way, and it's about the cavalry way, too. Those men know."

"How do you grip, then?"

"With the thigh. Try it. But when you're trotting you'd better stand in the stirrups and you can lean forward on the horn, for a rest."

Van grunted. He was experimenting.
