This animal is found in Persia, Asia Minor, Afghanistan, Beluchistan, Mongolia, Western China, Northern India, Syria, Turkey, North Africa and parts of Spain, but nowhere so generally or so finely developed as in Arabia. The two main species, not to speak of varieties, are the Southern, Arabian one-humped camel and the Northern, Bactrian two-humped camel. Each is specially adapted to its locality. The Bactrian camel is long-haired, tolerant of the intense cold of the steppes and is said to eat snow when thirsty. The Arabian species is short-haired, intolerant of cold, but able to endure thirst and extreme heat. It is incredible to Arabs that any camel-kind should have a double hump. A camel differs from a dromedary in nothing save blood and breed. The camel is a pack-horse; the dromedary a race-horse. The camel is thick-built, heavy-footed, ungainly, jolting; the dromedary has finer hair, lighter step, is easy of pace and more enduring of thirst. A caravan of camels is a freight-train; a company of Oman _thelul_-riders is a limited express. The ordinary caravan travels six hours a day and three miles an hour, but a good dromedary can run seventy miles a day on the stretch. A tradesman from Aneyza told Doughty that he had ridden from El Kasim to Taif and back, a distance of over 700 miles, in fifteen days! Mehsan Allayda once mounted his dromedary after the Friday midday prayer at El-Aly and prayed the next Friday in the great Mosque at Damascus about 440 miles distant. The Haj-road post-rider at Ma’an can deliver a message at Damascus, it is said, at the end of three days; the distance is over 200 miles. The Arabs have a saying that “the camel is the greatest of all blessings given by Allah to mankind.” One is not surprised that the meditative youth of Mecca who led the camels of Khadiyah, to Syria and back by the desert way, should appeal to the unbelievers in Allah and His prophet in the words, “_And do ye not look then at the camel how she is created?_” (Surah lxxxviii. 17 of the Koran.)
