At four o'clock they were on the road, Jacinto riding the mule that carried the blankets. He knew the trails through his own mountains well enough to follow them in the dark. Toward noon the Bishop suggested a halt to rest the mules, but his guide looked at the sky and shook his head. The sun was nowhere to be seen, the air was thick and grey and smelled of snow. Very soon the snow began to fall--lightly at first, but all the while becoming heavier. The vista of pine trees ahead of them grew shorter and shorter through the vast powdering of descending flakes. A little after midday a burst of wind sent the snow whirling in coils about the two travellers, and a great storm broke. The wind was like a hurricane at sea, and the air became blind with snow. The Bishop could scarcely see his guide--saw only parts of him, now a head, now a shoulder, now only the black rump of his mule. Pine trees by the way stood out for a moment, then disappeared absolutely in the whirlpool of snow. Trail and landmarks, the mountain itself, were obliterated. Jacinto sprang from his mule and unstrapped the roll of blankets. Throwing the saddle-bags to the Bishop, he shouted, "Come, I know a place. Be quick, Padre." The Bishop protested they could not leave the mules. Jacinto said the mules must take their chance. For Father Latour the next hour was a test of endurance. He was blind and breathless, panting through his open mouth. He clambered over half-visible rocks, fell over prostrate trees, sank into deep holes and struggled out, always following the red blankets on the shoulders of the Indian boy, which stuck out when the boy himself was lost to sight. Suddenly the snow seemed thinner. The guide stopped short. They were standing, the Bishop made out, under an overhanging wall of rock which made a barrier against the storm. Jacinto dropped the blankets from his shoulder and seemed to be preparing to climb the cliff. Looking up, the Bishop saw a peculiar formation in the rocks; two rounded ledges, one directly over the other, with a mouth-like opening between. They suggested two great stone lips, slightly parted and thrust outward. Up to this mouth Jacinto climbed quickly by footholds well known to him. Having mounted, he lay down on the lower lip, and helped the Bishop to clamber up. He told Father Latour to wait for him on this projection while he brought up the baggage. A few moments later the Bishop slid after Jacinto and the blankets, through the orifice, into the throat of the cave. Within stood a wooden ladder, like that used in kivas, and down this he easily made his way to the floor.
