The Arabs prefer mares to horses, it is true, but only for the three following reasons. The first is because they consider the profit to be derived from a mare as something very handsome, for it is well-known that as much as fifteen to twenty thousand _douros_ (from £3,000 to £4,000) have been received for the offspring of a single mare. Hence they may be often heard to exclaim: "The head of riches is a mare that produces a mare." And this idea gathers strength in their eyes from it having been said by our lord Mohammed, the messenger of Allah: "Give the preference to mares; their belly is a treasure, and their back a seat of honour. The greatest of blessings is an intelligent woman, or a prolific mare." These words are thus explained by commentators: "Their belly is a treasure," because a mare by means of her offspring increases the wealth of her master; and "their back is a seat of honour," because the pace of a mare is more easy and agreeable; some even going so far as to say that the easiness of her gait will after a time render her rider effeminate. The second motive is that the mare does not neigh in time of war like the horse, and is less sensitive as to hunger, thirst, and heat, and is therefore of greater use to a people whose riches consist principally in flocks of camels and sheep. It is known to all, that camels and sheep do not really thrive except in the Sahara, where the ground is so arid that many Arabs, being unable to procure water more than once in eight or ten days, accustom themselves to drink nothing but milk. This is one of the consequences of the great distance that frequently, on account of the pasturage, divides the encampment from a spot where there are wells. The mare is like the serpent: her strength increases in the hot season and in torrid regions. A snake that lives in a cold country or in water has very little life or venom, so that its bite is rarely mortal; whereas a snake that lives in a hot country is full of life, and the virulence of its poison is intensified. Contrary to the horse who is less capable of supporting the heat of the sun, the mare, owing doubtless to her temperament, finds her vigour doubled in the hottest season. The third and last motive is, the little attention required by the mare. She feeds on anything. Her owner leads or sends her to graze on the same herbage as the sheep and camels. There is no occasion to place a watchman in regular attendance. The horse, however, cannot dispense with being well kept, nor can his owner send him to the pasture without a _saïs_, or groom, to look after him.
