Pinto Ben is a pink-nosed cow-pony. A hundred head of cattle are rounded up for beef to be shipped alive to Chicago. Ben and his master, with Segundo Jim, are put in charge. In the Chicago stockyards, men who don't know range-bred cattle from a herd of mountain goats, calmly inform Jim and Ben's master that the steers are to be driven into the big pen. At the same instant two or three stock hands run behind the herd and begin shouting and waving their arms to start the cattle. The beasts, a thousand strong, with horns and hoofs beating the air, bellowing their rage, glaring with bloodshot eyes, thunder into the chute. The two men in front prepare for their death ride. Suddenly Pinto Ben flattens himself before a high, iron-bound gate, and leaps. The pony cleans the gate. The great wave of scorching breath falls back on the other side. Ben's master finds himself sitting on the ground, the head of his dying horse in his lap.
