It seemed to Tommy only a minute before he heard Johnny calling, and he crawled out to find him looking around in dismay. Every dog had disappeared except Sate.

“We are lost!” said Johnny. “We must try to get back or we shall freeze to death.” He climbed up on top of an ice-peak and looked around in every direction; but not a dog was in sight. “We must hurry up,” he said, “and go back after them. Why didn’t we tie them last night! We must take something to eat with us.” So they set to work and got out of the bag all they could carry, and with their guns and ammunition were about to start back.

“We must hide the rest of the things in a cache,” said Tommy, “so that if we ever come back we may find them.”

“What’s a cache?” said Johnny.

Tommy was proud that he knew something Johnny did not know. He explained that a “cache” was a hiding-place.

So they put the things back in the bag and covered them up with snow, and Tommy, taking up his gun and pack, gave a whistle to Sate, who was nosing around. Suddenly the snow around began to move, and out from under the snow appeared first the head of one dog and then of another, until every one—Buster and Muster and Fluster and the rest—had come up and stood shaking himself to get the snow out of his coat. Then Tommy remembered that his father had told him that that was the way the Eskimo dogs often kept themselves warm when they slept, by boring down deep in the snow. Never were two boys more delighted. In a jiffy they had uncovered the sled, eaten breakfast, fed the dogs and hitched them up again, and were once more on their way. They had not gone far, though it seemed to Tommy a long, long way, when the ice in the distance seemed to Tommy to turn to great mountain-like icebergs. “That’s where they are,” said Tommy. “They are always on icebergs in the pictures.” Feeling sure that they must be near them, they tied their dogs to the biggest blocks of ice they could find, and even tied Sate, and taking each his gun and a bag of extra ammunition, they started forward on foot. As Tommy’s ammunition was very heavy, he was glad when Johnny offered to carry it for him. Even so, they had not gone very far, though it seemed far enough to Tommy, when he proposed turning back and getting something to eat. As they turned they lost the North Star, and when they looked for it again they could not tell which it was. Johnny thought it was one, Tommy was sure it was another. So they tried first one and then the other, and finally gave themselves up as lost. They went supperless to bed that night or rather that time, and Tommy never wished himself in bed at home so much, or said his prayers harder, or prayed for the poor more earnestly. They were soon up again and were working along through the ice-peaks, growing hungrier and hungrier, when, going over a rise of ice, they saw not far off a little black dot on the snow which they thought might be bear or seal. With gun in hand they crept along slowly and watchfully, and soon they got close enough to see that there was a little man, an Eskimo, armed with a spear and bow and arrows and with four or five dogs and a rough little sled, something like Johnny’s sled, but with runners made of frozen salmon. At first he appeared rather afraid of them, but they soon made signs to him that they were friends and were lost and very hungry. With a grin which showed his white teeth he pointed to his runners, and borrowing Tommy’s knife, he clipped a piece off of them for each of them and handed it back with the knife; Tommy knew that he ought not to eat with his knife, but he was so hungry that he thought it would be overlooked. Having breakfasted on frozen runner, they were fortunate enough to make the Eskimo understand that they wanted to find a polar bear. He made signs to them to follow him and he would guide them where they would find one. “Can you shoot?” he asked, making a sign with his bow and arrow.

“Can we shoot!” laughed both Tommy and Johnny. “Watch us. See that big green piece of ice there?” They pointed at an ice-peak near by. “Well, watch us!” And first Johnny and then Tommy blazed away at it, and the way the icicles came clattering down satisfied them. They wished all that trip that the ice-peak had been a bear. So they followed him, and a great guide he was. He showed them how to avoid the rough places in the ice-fields, and, in fact, seemed quite as much at home in that waste of ice and snow as Johnny was back in town.

He always kept near the coast, he said, as he could find both bear and seal there. They had reached a very rough place, when, as they were going along, he stopped suddenly and pointed far off across the ice. Neither Tommy nor Johnny could see anything except ice and snow, try as they might. But they understood from his excitement that somewhere in the distance was a seal or possibly even a polar bear and, gun in hand, with beating hearts, they followed him as he stole carefully through the ice-peaks, working his way along, and every now and then cautioning them to stoop so as not to be seen.

So they crept along until they reached the foot of a high ridge of ice piled up below a long ledge of black rock which seemed to rise out of the frozen sea. Up this they worked their way, stooping low, the guide in front, clutching his bow and arrow, Johnny next, clutching his gun, and Tommy behind, clutching his, each treading in the other’s tracks. Suddenly, as he neared the top, the guide dropped flat on the snow. Johnny followed his example and Tommy did the same. They knew that they must be close to the bear and they held their breath; for the guide, having examined his bow and arrows carefully, began to wriggle along on his stomach. Johnny and Tommy wriggled along behind him, clutching their guns. Just at the top of the ledge the guide quietly slipped an arrow out of his quiver and held it in his hand, as he slowly raised his head and peeped over. Johnny and Tommy, guns in hand, crept up beside him to peep also. At that instant, however, before Tommy could see anything, the guide sprang to his feet. “Whiz,” by Tommy’s ear went an arrow at a great white object towering above them at the entrance of what seemed a sort of cave, and two more arrows followed it, whizzing by his ear so quickly that they were all three sticking in deep before Tommy took in that the object was a great white polar bear, with his head turned from them, in the act of going in the cave. As the arrows struck him, he twisted himself and bit savagely at them, breaking off all but one, which was lodged back of his shoulder. As he reared up on his hind legs and tried to get at this arrow, he seemed to Tommy as high as the great wardrobe at home. Tommy, however, had no time to do much thinking, for in twisting around the bear caught sight of them. As he turned toward them, the guide with a yell that sounded like “Look out!” dodged behind, but both Tommy and Johnny threw up their guns and pulled the trigger. What was their horror to find that they both had forgotten to load their guns after showing the guide how they could shoot. The next second, with jaws wide open, the bear made a dash for them. Tommy’s heart leapt into his throat. He glanced around to see if he could run and climb a tree, for he knew that grizzlies could not climb, and he hoped that polar bears could not climb either, while Tommy prided himself on climbing and had often climbed the apple-tree in the pasture at home; but there was not a tree or a shrub in sight, and all he saw was the little guide running for life and disappearing behind an ice-peak.

“Run, Johnny!” cried Tommy, and, “Run, Tommy!” cried Johnny at the same moment. But they had no time to run, for the next second the bear was upon them, his eyes glaring, his great teeth gleaming, his huge jaws wide open, from which came a growl that shook the ice under their feet. As the bear sprang for them Johnny was more directly in his way, but, happily, his foot slipped from under him and he fell flat on his back just as the bear lit, or he would have been crushed instantly. Even as it was, he was stunned and lay quite still under the bear, which for the moment seemed to be dazed. Either he could not tell what had become of Johnny, or else he could not make up his mind whether to eat Johnny up at once or to leave him and catch Tommy first and then eat them both together. He seemed to decide on the latter, for, standing up, he fixed his eyes on Tommy and took a step across Johnny’s prostrate body, with his mouth open wider than before, his eyes glaring more fiercely, and with a roar and a growl that made the ice-peaks shed a shower of icicles. Then it was that Tommy seemed to have become a different boy. In fact, no sooner had Johnny gone down than Tommy forgot all about himself and his own safety, and thought only of Johnny and how he could save him. And, oh, how sorry he was that he had let Johnny carry all the ammunition, even though it was heavy! For his gun was empty and Johnny had every cartridge. Tommy was never so scared in all his life. He tried to cry out, but his throat was parched, so he began to say his prayers, and remembering what Santa Claus had said about boys who asked only for themselves, he tried to pray for Johnny.
