It was true. Jimmie appeared on the chassis of the monoplane, and seemed to be attempting to climb into the body of the craft. The boys saw him lean far out to peer around the curved side of the body. As the machine rose the pilot described an immense circle, evidently trying to get clear of the surrounding trees before attempting to lay a course in any direction. With the added burden of Jimmie's shifting weight he seemed to have trouble in keeping the machine steadied.
Two shots in quick succession were heard. Jimmie and The Rat were exchanging compliments. Neither had scored.
The machine was now swinging back toward the clearing, where the boys stood lost in amazement at the predicament of their chum.
Harry, who was nearest the Grey Eagle, clambered aboard and unshipped the magazine rifle Jimmie had used early the day before. However, he could get no opportunity to shoot without endangering their chum.
"He's coming right over us!" cried Jack in an excited tone.
"Sure! He's circling around, trying to get high enough to clear these big trees!" answered Ned. "But how can we help Jimmie?"
"Take a shot at the pilot, Harry!" advised Jack eagerly.
"Don't shoot, Harry!" cautioned Ned. "You might hit The Wolf!"
Nearer swept the aeroplane and its warring passengers. Jimmie and The Rat continued to exchange shots, but the conditions were unfavorable to accurate marksmanship. Suddenly the machine turned upward.
