Jack, for his part, had very soon become a brilliant horseman, lissom and fearless, an adept at leaping through the hoops and vaulting the bars. Thus the two seemed made for each other, both in body and mind. They bore the hardships of the life together, and they shared its successes; by dint of standing so often back against back and muzzle against muzzle, they found their hearts brought close together too, and became fast friends. Murph was never to be seen without Jack; wherever Jack was, Murph was there as well; they lived curled up on the same rug, in the same corner, under the same table, Murph licking Jack in the neck, and Jack stroking Murph’s nose, each bound to each in perfect trust and amity. V Murph was older than Jack by nearly nine years, and his years made him nearly as serious-minded as his friend. But it was a different sort of gravity. Murph was neither morose nor disillusioned; his was the gentle seriousness of old age. He had seen many things since he had been in the world, but life did not appear to have left only its dregs in him. He still believed in springtide, in friendship, in the master’s kind heart; then he had neither family nor native land to regret, for he had been born in the menagerie of a father and mother broken in like himself to circle the trapeze and leap through the hoop. His horizon was bounded by the four walls of the caravan in which, as a puppy still sucking at his mother’s breast, he had been carted from fair to fair. Day by day he had watched from behind the window-panes the long procession of cities and countries filing past; he had visited most parts of Europe, in company with the strange _omnium-gatherum_ of apes, goats, parrots, and dogs that at each halting-place was the delight of the infant population. But he had never taken it upon him to covet the kingdom of this world; he had never craved to roam at liberty through the streets; never, in one word, had he so much as dreamt of playing truant. He was a very learned dog, and, like other learned people, he lived absorbed in his own thoughts, self-centred within the circle of his meditations, seeking nothing of things outside. VI
