“We shall have to kill him and eat his flesh raw

“We shall have to kill him and eat his flesh raw,” I said, patting the poor yak that lay patiently at our side.
“Perhaps we may find game in the morning,” answered Leo, still hopeful.
“And perhaps we may not, in which case we must die.”
“Very good,” he replied, “then let us die. It is the last resource of failure. We shall have done our best.”
“Certainly, Leo, we shall have done our best, if sixteen years of tramping over mountains and through eternal snows in pursuit of a dream of the night can be called best.”
“You know what I believe,” he answered stubbornly, and there was silence between us, for here arguments did not avail. Also even then I could not think that all our toils and sufferings would be in vain.
The dawn came, and by its light we looked at one another anxiously, each of us desiring to see what strength was left to his companion. Wild creatures we should have seemed to the eyes of any civilized person. Leo was now over forty years of age, and certainly his maturity had fulfilled the promise of his youth, for a more magnificent man I never knew. Very tall, although he seemed spare to the eye, his girth matched his height, and those many years of desert life had turned his muscles to steel. His hair had grown long, like my own, for it was a protection from sun and cold, and hung upon his neck, a curling, golden mane, as his great beard hung upon his breast, spreading outwards almost to the massive shoulders. The face, too — what could be seen of it — was beautiful though burnt brown with weather; refined and full of thought, sombre almost, and in it, clear as crystal, steady as stars, shone his large grey eyes.
And I— I was what I have always been — ugly and hirsute, iron-grey now also, but in spite of my sixty odd years, still wonderfully strong, for my strength seemed to increase with time, and my health was perfect. In fact, during all this period of rough travels, although now and again we had met with accidents which laid us up for awhile, neither of us had known a day of sickness. Hardship seemed to have turned our constitutions to iron and made them impervious to every human ailment. Or was this because we alone amongst living men had once inhaled the breath of the Essence of Life?
Our fears relieved — for notwithstanding our foodless night, as yet neither of us showed any signs of exhaustion — we turned to contemplate the landscape. At our feet beyond a little belt of fertile soil, began a great desert of the sort with which we were familiar — sandy, salt-encrusted, treeless, waterless, and here and there streaked with the first snows of winter. Beyond it, eighty or a hundred miles away — in that lucent atmosphere it was impossible to say how far exactly — rose more mountains, a veritable sea of them, of which the white peaks soared upwards by scores.
As the golden rays of the rising sun touched their snows to splendour, I saw Leo’s eyes become troubled. Swiftly he turned and looked along the edge of the desert.
“See there!” he said, pointing to something dim and enormous. Presently the light reached it also. It was a mighty mountain not more than ten miles away, that stood out by itself among the sands. Then he turned once more, and with his back to the desert stared at the slope of the hills, along the base of which we had been travelling. As yet they were in gloom, for the sun was behind them, but presently light began to flow over their crests like a flood. Down it crept, lower, and yet lower, till it reached a little plateau not three hundred yards above us. There, on the edge of the plateau, looking out solemnly across the waste, sat a great ruined idol, a colossal Buddha, while to the rear of the idol, built of yellow stone, appeared the low crescent-shaped mass of a monastery.
