How is it, we ask of those more intimately acquainted with the metaphysics of the Houyhnhnm than we pretend to be? Do the saddle or the rein convey, like metallic tractors, vibrations of the spirit betwixt the two? We know not, but this much is certain, that no servant partakes so much of the character of his master as the horse. The steed we are wont to ride becomes a portion of ourselves. He thinks and feels with us. As we are lively, he is sprightly; as we are depressed, his courage droops. In proof of this, let the reader see what horses some men make--_make_, we say, because in such hands their character is wholly altered. Partaking, in a measure, of the courage and the firmness of the hand that guides them, and of the resolution of the frame that sways them--what their rider wills, they do, or strive to do. When that governing power is relaxed, their energies are relaxed likewise; and their fine sensibilities supply them with an instant knowledge of the disposition and capacity of the rider. A gift of the gods is the gallant steed, which, like any other faculty we possess, to use or to abuse--to command or to neglect--rests with ourselves; he is the best general test of our own self-government. Black Bess's action amply verified what we have just asserted; for during Turpin's momentary despondency, her pace was perceptibly diminished and her force retarded; but as he revived, she rallied instantly, and, seized apparently with a kindred enthusiasm, snorted joyously as she recovered her speed. Now was it that the child of the desert showed herself the undoubted offspring of the hardy loins from whence she sprung. Full fifty miles had she sped, yet she showed no symptoms of distress. If possible, she appeared fresher than when she started. She had breathed; her limbs were suppler; her action was freer, easier, lighter. Her sire, who, upon his trackless wilds, could have outstripped the pestilent simoom; and with throat unslaked, and hunger unappeased, could thrice have seen the scorching sun go down, had not greater powers of endurance. His vigor was her heritage. Her dam, who upon the velvet sod was of almost unapproachable swiftness, and who had often brought her owner golden assurances of her worth, could scarce have kept pace with her, and would have sunk under a third of her fatigue. But Bess was a paragon. We ne'er shall look upon her like again, unless we can prevail upon some Bedouin chief to present us with a brood mare, and then the racing world shall see what a breed we will introduce into this country. Eclipse, Childers, or Hambletonian, shall be nothing to our colts, and even the railroad slow travelling, compared with the speed of our new nags!
