But when I came up near the creek I unexpectedly rode in among a herd of horses.

The animals became frightened, and ran off in all directions.

Without pausing to make any apology, I backed out as quickly as possible.

But just at that minute a dog, not fifty yards away, set up a howl.

Soon I heard Indians talking.
They had been guarding the horses, and had heard the hoofbeats of my horse.
