The same fear was in Ned's mind just then, and it was very natural that it should be. How else could the disappearance of the boys be accounted for?
"We can't tell anything about it," he answered evasively, "and it would be very foolish to jump at the worst conclusions. It will be our best plan to start down the creek at once, and I have no doubt we'll find the camp before very long. It's not at all likely the boys have moved far away."
"But they may have concealed themselves somewhere," said Clay, "and besides we don't know which bank they are on."
"We'll keep a sharp lookout on both sides," replied Ned. "If we shout every now and then I don't think we can miss them. We had better start right away. I'm getting tired of wandering about the country in this fashion. It will feel awfully good to climb in a canoe again."
Clay warmly assented to this, and after a last lingering glance at the shady thickets and the eddying surface of the pool, the boys plodded off through the woods.
For a time they experienced no difficulty in following the edge of the creek, and thus scrutinizing the opposite shore as well as the one they were on. Occasionally they shouted; first at rare intervals, then more frequently as they advanced farther along the creek.
At the expiration of an hour and a half they had traveled three or four miles, and rounded a couple of large bends without getting any response to their calls, or finding the least trace of the missing boys.
Then a precipitous hill blocked the way, extending a considerable distance along the creek, and leading sheer to the water from a variable height of forty to sixty feet.
"No use in going around it, Ned. We'll follow the crest so we can watch the opposite shore."
They easily gained the summit, and found a sort of open path between the edge of the thick pine forest and the verge of the cliff. It was half a dozen feet wide and had quite a downward slope. There was quite an element of danger connected with the ascent, since it was slippery with a coating of pine needles. The boys did not think of this, however. Of course they kept close to the trees, but as their gaze was fixed on the opposite shore, which was in plain view far below them, they could not pick out their footing as carefully as they should have done.
