In the afternoon everyone was fresh, and the Juheina began to match their camels against one another. At first it was two and two, but the others joined, till they were six abreast. The road was bad, and finally, one lad cantered his animal into a heap of stones. She slipped, so that he crashed off and broke an arm. It was a misfortune: but Mohammed coolly tied him up with rags and camel-girths, and left him at ease under a tree to rest a little before riding back to Ugila for the night. The Arabs were casual about broken bones. In a tent at Wadi Ais I had seen a youth whose forearm had set crookedly; realising this, he had dug into himself with a dagger till he had bared the bone, re-broken it, and set it straight; and there he lay, philosophically enduring the flies, with his left forearm huge under healing mosses and clay, waiting for it to be well.
