“We’ll get our axes and try,” Jack said, reluctantly.

“Then make haste!” Greer shouted. “At all events we must leave this place, for the fire will soon be here. Come!”

When the boys turned to verify this statement they saw that the planes of the aeroplane were red with the reflection of the blaze below, and that the creeping fire was already showing at the lip of the plateau.

“The aeroplane is doomed, I guess,” wailed Jack, and Pat thought he saw a look of satisfaction in Greer’s face as the words reached his ears.

The smoke was now rolling over the plateau in great clouds, but through it Pat thought he saw figures moving from the south slope toward the aeroplane. Calling out to Jack, he sprang toward the machine, the suspicion in his mind that these were confederates of the alleged forester, and that the machine was, after all, the main point of attack.

Greer saw the movement and darted toward the boy as if to block his way, but Pat struck out viciously and turned him back. Then a bit of flame sprang up in the cloud of smoke which was sweeping over the plateau. It seemed to Pat that an attempt to burn the machine in advance of the arrival of the forest fire was being made.

When he darted forward again Greer caught him by the shoulder and hurled him away.

“Get your axes!” he shouted. “There is no time to waste here.”

Then the smoke lifted for an instant and Pat saw three figures rise above the rim of the northern slope and hasten toward the aeroplane. Their arrival there was followed by shots and calls for assistance. Then the smoke shut down again, and the roaring of the flames drowned all other sounds.

Greer stood for an instant, braced against the wind, shielding his face from the hot blasts scorching the grass of the plateau, then turned and ran. Then both boys heard a call from the direction of the machine.
