Passing before a horse the Prophet began to rub his face with his sleeve, saying: "Allah has been wrathful with me because of horses." "Felicity is attached to the forelocks of horses." And it is on their account that their owners can reckon on the aid of Allah. Therefore it is your duty to wipe their forelocks with your hands. A wise man has said:—"The noble labours with his hands without a blush, in three cases; for his horse, for his father, and for his guest." One mode of judging of a horse is to measure him from the root of the mane close to the withers and descend to the end of the upper lip between the nostrils. They then measure from the root of the mane to the end of the tail-bone, and if the forepart is longer than the hindpart there is no doubt the horse will have excellent qualities. To ascertain if a young horse will grow any more or not, the Arabs measure first from the knee to the highest point situated in the prolongation of the limb above the withers, then from the knee downwards to the beginning of the hair above the coronet (to the crust of the hoof): if these two measures are to one another as two-thirds to one-third, the horse will grow no more. If this proportion does not exist, the animal has not done growing, for it is absolutely necessary that the height from the knee to the withers should represent in a full grown horse exactly double the length of the leg from the knee to the hoof. In the desert the curry-comb is never used, the horses are cleaned with the nose-bag, which is made of horse hair, and are frequently washed if the weather is favourable. Milk is their ordinary drink. Should it happen to run short, the Arabs do not hesitate to go a considerable distance to find clear and pure water for them. The barley ought to be heavy, very clean, without any bad smell, and completely clear of the impurities which are unavoidably mixed with it in the "silos." The horses are covered with good _djellale_, which fully protect the loins, the belly, and the chest. They are manufactured in the tribe. Those that are made with care are water proof. There are some coats which must be preserved with equal attention from cold and from heat. Experience has demonstrated that this is necessary for all horses of a light colour, beginning with the white, the fineness of whose skin makes him very susceptible. In the sun he melts like butter: In the rain he melts like salt.
