How much time passed in the sleep he could never exactly learn; probably six to seven hours. He was aroused by what seemed to be icy-cold rats’ feet scampering over his face, and as he started and brushed them away with his hand, his ears became alive to a terrible, roaring sound. He started up, alarmed, at first bewildered, then suddenly wide awake. The cold feet upon his face were little threads of water trickling from above; the fearful roaring came from a storm—a hurricane of mixed rain, wind, cloud, and snow. It was day, yet still darker than the Arctic summer night, so dense and black was the tempest. When Jon crept out of the crevice, he was nearly thrown down by the force of the wind. The first thing he did was to seek the two lines of stones he had arranged for his guidance. They had not been blown away as he feared; and the sight of the arrow-head made his heart leap with gratitude to the Providence which had led him, for without that sign he would have been bewildered at the very start. Returning to the cleft, which gave a partial shelter, he ate the greater part of his remaining store of food, fastening his thick coat tightly around his breast and throat, and set out on the desperate homeward journey, carefully following the lighter streak of rock across the plain.
He had not gone more than a hundred yards when he fancied he heard a sharp, hammering sound through the roar of the tempest, and paused to listen. The sound came rapidly nearer; it was certainly the hoofs of many horses. Nothing could be seen; the noise came from the west, passed in front of Jon, and began to die away to the eastward. His blood grew chilled for a moment. It was all so sudden and strange and ghostly that he knew not what to think; and he was about to push forward and get out of the region where such things happened, when he heard, very faintly, the cry which the Icelanders use in driving their baggage-ponies. Then he remembered the deep gorge he had seen to the eastward, before reaching the crater; the invisible travellers were riding toward it, probably lost, and unaware of their danger.
This thought passed through Jon’s mind like a flash of lightning; he shouted with all the strength of his voice.
He waited, but there was no answer. Then he shouted again, while the wind seemed to tear the sound from his lips and fling it away—but on the course the hoofs had taken.
This time a cry came in return; it seemed far off, because the storm beat against the sound. Jon shouted a third time, and the answer was now more distinct. Presently he distinguished words:
“Come here to us!”
“I cannot!” he cried.
In a few minutes more he heard the hoofs returning, and then the forms of ponies became visible through the driving snow-clouds. They halted, forming a semicircle in front of him; and then one of three dim, spectral riders leaning forward again called: “Come here!”
“I cannot!” Jon answered again.
Thereupon, another of the horsemen rode close to him, and stared down upon him. He said something which Jon understood to be: “Erik, it is a little boy!”—but he was not quite sure, for the man’s way of talking was strange. He put the words in the wrong places, and pronounced them curiously.
