and grotesque and scanty-leaved, nourished for a thousand years on the bones that whiten the stony ground at their roots; the interior lit faintly with the rays of the departing sun, chill and grey, and silent and motionless--the huanacos' Golgotha. In the long centuries, stretching back into a dim immeasurable past, so many of this race have journeyed hither from the mountain and the plain to suffer the sharp pang of death, that, to the imagination, something of it all seems to have passed into that hushed and mournful nature. And now one more, the latest pilgrim, has come, all his little strength spent in his struggle to penetrate the close thicket; looking old and gaunt and ghostly in the twilight; with long ragged hair; staring into the gloom out of death-dimmed sunken eyes. England has one artist who might show it to us on canvas, who would be able to catch the feeling of such a scene--of that mysterious, passionless tragedy of nature--I refer to J. M. Swan, the painter of the "Prodigal Son" and the "Lioness Defending her Cubs." To his account of the animal's dying place and instinct, Darwin adds: "I do not at all understand the reason of this, but I may observe that the wounded huanacos at the Santa Cruz invariably walked towards the river." It would, no doubt, be rash to affirm of any instinct that it is absolutely unique; but, putting aside some doubtful reports about a custom of the Asiatic elephant, which may have originated in the account of Sindbad the Sailor's discovery of an elephant's burial place, we have no knowledge of an instinct similar to that of the huanaco in any other animal. So far as we know, it stands alone and apart, with nothing in the actions of other species leading up, or suggesting any family likeness to it. But what chiefly attracts the mind to it is its strangeness. It looks, in fact, less like an instinct of one of the inferior creatures than the superstitious observance of human beings, who have knowledge of death, and believe in a continued existence after dissolution; of a triba that in past times had conceived the idea that the liberated spirit is only able to find its way to its future abode by starting at death from the ancient dying-place of the tribe or family, and thence moving westward, or skyward, or underground, over the well-worn immemorial track, invisible to material eyes.
