So he was very cautious as he began to slowly push back. Inch at a time he moved, save when very sure of his cover. All the while he kept a vigilant watch over the parties in the open spot.

Once Elmer's heart seemed to be almost in his mouth. This was when the fatter one of the two suddenly craned his neck in an attitude of scrutiny, as though he fancied he had seen something moving off there in the underbrush.

Of course, if he made the first move as though bent on an investigation, Elmer meant to spring boldly to his feet and run for it, possibly in a direction away from the spot where he had left his comrades.

But the man did not even get up from his seat. Judging from his looks, Elmer decided that he must be a lazy sort of fellow. And then again, why should the tramp entertain the least suspicion that any human being could be loitering around the old McGraw Camp, so far removed from the railroad, and even the dirt roads leading to main thoroughfares?

When things seemed all quiet again, Elmer continued his wriggling movements, and presently arrived at a point where he could make better progress, as the cover was heavier.

At length he made a detour, approached the cabin again, and scanned its immediate surroundings. Satisfied with what he had learned, he proceeded to find the impatient scouts, from whom he had been absent now almost an hour.

They were in a state of mind approaching insurrection. Of course all manner of dreadful things were suggested under their breath, as the boys huddled together. Every slight sound made them start and look hurriedly around. When a gray squirrel dropped a nut it seemed as though a gun had gone off; and later on when he himself frisked around a neighboring tree butt in search of a further supply, Landy Smith could hardly keep from crying out, his nerves being all on edge with the strain.

Chatz had looked at his watch for the twentieth time, and murmurs were beginning to rise all along the line, when suddenly keen-eyed Mark exclaimed:

"I saw something move right then, fellows; there it is again. It's Elmer, all right; and he looks as though he might have discovered something of importance!"

"Bully! bully!" chuckled Ty Collins; "now we'll get into action, I guess!"
