"Most likely to 'Dunham's open,'" said Tom, "and that's two miles; but I know the way. Come on. We've got to get them." We set off at a run, following Thomas along a trail through the forest across the upper valley of the Robbins Brook, but had not gone more than a mile when the storm came on, not large snowflakes, but thick and fine, driven by wind. It came with a sudden darkening of the woods and a strange deep sound, not the roar of a shower, but like a vast elemental sigh from all the surrounding hills and mountains. The wind rumbled in the high, bare tree-tops and the icy pellets sifted down through the bare branches and rattled inclemently on the great beds of dry leaves. "Shall we go back?" exclaimed Halse. "No, no; come on!" Thomas exclaimed. "We've got to get those sheep in to-night." We ran on; but the forest grew dim and obscure. "I think we have gone wrong," Addison said. "I 'most think we have," Thomas admitted. "I ought to have taken that other path, away back there." He turned and ran back, and we followed to where another forest path branched easterly; and here, making a fresh start, we hastened on again for fifteen or twenty minutes. "Oughtn't we to be pretty near Dunham's open?" demanded Addison. "Oh, I guess we will come to it," replied Tom. "It is quite a good bit to go." Thereupon we ran on again for some time, and crossed two brooks. By this time the storm had grown so blindingly thick that we could see but a few yards in any direction. Still we ran on; but not long after, we came suddenly on the brink of a deep gorge which opened out to the left on a wide, white, frozen pond. Below us a large brook was plunging down the "apron" of a log dam. Thomas now pulled up short, in bewilderment. Addison laughed. "Do you know where you are?" said he. "Tom, that is Stoss Pond and Stoss Pond stream. There's the log dam and the old camp where Adger's gang cut spruce last winter. I know it by those three tall pine stubs over yonder." Tom looked utterly confused. "Then we are five miles from home," he said, at length. "We had better go back, too, as quick as we can!" Halse exclaimed, shivering. "It's growing dark! The ground is covered with snow, now!" Addison glanced around in the stormy gloom and shook his head. "Tom," said he, "I don't believe we can find our way back. In fifteen minutes more we couldn't see anything in the woods. We had better get inside that camp and build a fire in the old cook-stove." "I don't know but that we had," Tom assented. "It's an awful night. Only hear the wind howl in the woods!"
