Conquest of Cochise1953

Cochise:
These young ones are being taught discipline and endurance. They all start off running, not full speed, but trotting. Somewhere along the road, a brave with water in a little container gives it to the runner and says, "Take a mouthful, but do not swallow." They run four miles with the water in their mouths. At the end of the course, each is inspected to see if he still has the water. If one has swallowed, the trainers see to it that he does not do it a second time.
