Haj Allaih was a camel driver hired for the US Army's "pack camel" experiment in the mid-1800's. The experiment was a failure (camels are ill-tempered, obnoxious beasts) and the camels were released into the wilds of the US Southwestern desert. "Hi Jolly", as he was called, stayed in America the rest of his life, eventually making his last camp in Quartzite, Arizona. There he could watch for any remaining camels, holding true to his charge.
