ting the damage.

"I guess not," replied Oh-Pshaw, wincing with the pain, "though it hurts
like fury. I guess it's just skinned."

Sahwah bound up the two places that were bleeding the most with her
handkerchief and Oh-Pshaw's and was gently replacing the stocking when
her ears caught a sound--a noise like the humming of a giant bee.
"What's that noise?" asked Oh-Pshaw.

"It's an aeroplane," said Sahwah. "It must be _the_ aeroplane that's
coming over from Philadelphia to take part in the sham battle. The one
has been in Oakwood all day, but the other hadn't arrived yet when I
started out to look for you. It's coming in this direction, over the
woods. Come on, let's run to the open space by the Devil's Punch Bowl
and see if he flies over there." Sahwah seized Oh-Pshaw by the hand and
started away on a run, and Oh-Pshaw followed as best she could for the
pain in her knee. The humming noise grew louder and louder as they ran,
and then suddenly it stopped altogether.

"Where is he, is he gone?" asked Oh-Pshaw in disappointment.

"I can't imagine," replied Sahwah, looking up in bewilderment when they
came out beside the Punch Bowl. "No, there he is," she cried, as the
machine suddenly shot into sight directly above them. "Oh-Pshaw!" she
screamed, "it's coming down!"

Rooted to the spot, they watched it, as nose downward the machine came
rushing toward them, struck against the rock cliffs high above them and
dropped with a terrific splash into the Devil's Punch Bowl.

CHAPTER XVIII

OUT OF A CLEAR SKY

It happened so quickly that the two girls had no time to jump back out
of the way; they were caught in the deluge of water that shot out from
the Punch Bowl on every side. When they got their eyes open again the
luckless flying machine lay before them in the water, a mass of
wreckage. Oh-Pshaw gave a little muffled shriek and sat down on a log,
hiding her face in her hands. Sahwah shook her roughly by the shoulder.

"_Oh-Pshaw!_ The man's under the machine, in the water!"

Oh-Pshaw shuddered and did not look up.

"_Oh-Pshaw! Oh-Pshaw!_ He'll drown!"

Oh-Pshaw looked up, still shuddering, and gazed in fascinated horror at
the thing in front of her. "Isn't he--dead?" she asked in a hoarse
whisper.

"No, he isn't, he's _struggling_. Don't you see the water moving? I'm
going out and help him," Sahwah exclaimed with sudden resolution.

She waded swiftly out into the water until it became too deep for her
to
