A second good game was to cannon one galloping camel with another, and crash it into a near tree. Either the tree went down (valley trees in the light Hejaz soil were notably unstable things) or the rider was scratched and torn; or, best of all, he was swept quite out of his saddle, and left impaled on a thorny branch, if not dropped violently to the ground. This counted as a bull, and was very popular with everyone but him.
