All being ready, they started, but progress was slow, both for caution's sake, and because in the absence of ice-creepers their feet could obtain little hold upon the slippery surface. Not far out lay a chain of small islands, around which were stretches of open water, now lashed into foam by the wind, and lapping hungrily at the weakening edges of the ice. It was necessary to go between two of these islands where the ice was not to be depended on, but this dangerous passage was made in safety, and all breathed more easily when they reached the firmer ice of the broad, open lake. The rain now fell, or rather drove, in torrents, and the travellers were wet to the skin. Four miles away lay the shore they sought, at the southern base of the dark mountain slopes. At the head of the company went Lucky, his black, narrow eyes, almost Mongolian in shape, keenly fixed on the ice, and the rude drag scraping along behind him. Then came Coffee Jack, then Uncle Will with the lake trout slipping after his load, and finally Roly, David, and Mr. Bradford. It was hard work,—hard upon hands and arms,—though the lame backs and shoulders were somewhat relieved by the new mode of travel.
After an hour and a half, the party approached the southwest shore. Here the ice became more treacherous. Sometimes they could feel it settle beneath their feet, as if an upper layer had been pressed down upon an underlying one. There were many little cavities a few inches deep and filled with water, at the bottom of which were slender green plants like seaweed, which seemed to possess the power of melting the ice immediately around them. Strict orders were given that no one should approach within thirty feet of another, lest their combined weight should prove disastrous. And now Lucky stopped and pointed toward the shore.
"Water!" he exclaimed.
Consternation was depicted on every face.
"It's too true," said Uncle Will, as he made out the dark line all along the beach. "Looks as if we couldn't get off the ice now we're on it."
"We've got to get off," declared Mr. Bradford, decisively. "There's nothing else to do. We can't go back. Very likely the ice-bridge is gone by this time."
"Can't we chop out an ice-raft?" suggested David, who recalled certain youthful adventures upon the mill-pond at home.
Uncle Will nodded. "We'll do that very thing," said he, "if we can't find a crossing. First, however, let us explore a little."
Contrary to all expectation, as they rounded a rocky point, they discovered beyond it a narrow ice-strip not more than fifty feet wide, similar to the one they had crossed that morning, but much weaker, spanning the hundred feet to the beach. One at a time they passed across in safety and stood at last, with a great sense of thankfulness and relief, upon the solid ground. And now the rain ceased, and the cheerful sun broke through the masses of clouds.
