Certain now that the gun was secure, she adjusted the ammunition belt as Bill had instructed her. Then she raced aft again and overside. When she returned, she brought the wheel blocks with her. These she dropped in the cabin, saw to it that the door was properly fastened, then took her place at the controls forward.

The night was overcast and starless; the ceiling unusually low, and so far as she could judge there was not the slightest breath of wind. She switched on the plane's searchlight and started the engine.

The trees at the far end of the wood lot were uncomfortably near and high. Yet Bill had judged a take off from such a place to be possible, or he would never have parked there.

The big Loening was moving now--rolling drunkenly over the rough ground, yet gaining speed with every foot. She widened her throttle, steadily, fully--at the same time pushing the stick well forward. Then as the amphibian gained still more speed and she felt the tail lift clear, she eased the stick steadily back to neutral.

They were racing over the field now. She gave the elevators a slight upward pressure. The wheels lifted clear, but the trees at the edge of the lot were perilously near. She knew that when a plane leaves the ground its speed is not far above stalling point. And with these trees so close, to stall now would precipitate a bad crash--and failure.

Dorothy, therefore, kept the nose level for an instant or two, a dangerously short instant, she feared. Back came her stick again. The plane was climbing at last but at a frightfully precipitous angle. Would they make it? Would the throbbing engine continue to function under the unaccustomed strain?

Dorothy bit her lip. She eased off slightly as the motor coughed; but pulled the stick back almost immediately.

They were abreast the treetops now.--They were over. But with a margin so small that Dorothy was certain the wheels had brushed the branches.

She eased their angle of ascent, but still continued to climb. Then when she was sure they were well above the crest of the hill, she leveled off and banked to the left.

Once more she leveled off and turned on the electrical mechanism which raised the plane's landing gear.
