"Olalola says the wind has died down," said Barwell Dawson. "We may as well make the most of it." A hasty breakfast was prepared, and inside of half an hour they were again on the way, toiling over ice that was rough in the extreme. They pushed on steadily until noon, when, it being bright sunlight, Professor Jeffer took another observation. "One hundred and sixteen miles more," he said, after his calculations were complete. "We are gradually lessening the distance! We shall make it after all!" And his face showed his enthusiasm. To such a scientist as the professor, gaining the Pole meant far more than it did to the boys. In the middle of the afternoon came another setback. Another lead came into view, broad, and with the water flowing swiftly. At this the Esquimaux shook their heads dismally. "We cannot go over that," said one, in his native tongue. "We must," answered Barwell Dawson, briefly. With the North Pole so close at hand, he was determined that nothing should keep him from reaching the goal. The party gathered at the edge of the lead, and there found the ice cracked and uncertain. Andy was with Olalola, who had a sledge drawn now by but six dogs. Suddenly, as the men were walking up and down the shore looking for some means of crossing the water, there came an ominous cracking. Andy tried to leap back, and so did Olalola, but ere they could do so the ice upon which they and the dogs and sledge were located broke away from the main field, and floated out into the lead. "Look out, there!" exclaimed Chet, in horror. "Throw us a rope!" yelled Andy, while Olalola uttered a cry in his native language. But no rope was handy, and in a few seconds the strong current of the water carried the cake of ice far out into the lead. It still kept its balance, but there was no telling how soon it might turn over and send Andy, the Esquimau, and the dogs to their death. "Oh, we must save Andy!" screamed Chet. "What can we do?" "We'll do all we can," answered the explorer. He ran to one of the loads and tore from it a long rope. Then he hurried along the edge of the lead, in the direction whence the current was carrying the flat cake of ice with its human freight. Andy and Olalola saw the movement, and both understood at once that they must make some sort of a fastening for the rope, should they be able to catch it. With a sharp-pointed knife, Andy picked away a small hole, and in it set a peg taken from the sledge. While the lad was doing this, Barwell Dawson curled up the rope as if it were a lasso. His outings on the plains now stood him in good stead, and he threw the end of the rope with the skill of a cowboy lassoing cattle. Olalola caught it and slipped it over the peg, and then he and Andy did all they could to hold the peg in the ice. It now became a question if the explorer could haul the floating ice in, or if the current would be too strong for him. Chet came to his aid, and so did two of the Esquimaux.
