A number of them would surround a herd and dash in on it, each one killing from one to four buffaloes.

I had gone out in company with Major North, and watched them make a "surround." Twenty Pawnees, circling a herd, killed thirty-two buffaloes.
As they were cutting up the animals, another herd appeared.

The Pawnees were getting ready to surround it, when I asked Major North to keep them back to let me show them what I could do.

He did as I requested.

I knew Buckskin Joe was a good buffalo horse, and, feeling confident that I would astonish the Indians, I galloped in among the herd.
