ed the wide parlor, traversed the dark hall to Gooding's room and
returned with mattress, pillows and blankets. After a great deal of
panting and pulling, the little party was settled for sleep.

It must have been an hour later when they were startled into sitting
posture, their hearts in their throats, by piercing screams which rang
out over the mesa, one after another in quick succession.

"David, David, David," gasped Carol.

"I'm right here, Carol; we're all right," he assured her quickly.

Miss Landbury swayed dizzily and fell back, half-conscious, upon the
pillows. Gooding, with one bound, landed on David's bed, nearly

Lights flashed quickly from tent to tent on the mesa, frightened voices
called for nurses, doors slammed, bells rang, and nurses and porters
rushed to the rescue.

"Who was it?" "Where was it?" "What is it?"

"I was asleep, and I heard my name called, and I looked up. There was
a white shadow on the door. I seized my pillow and threw it with all
my might, and there was a loud crash and a roar, and then began that
drip, drip, drip,--oh-h-h!"

"You silly thing," said Miss Alien. "Of course there was a crash. You
knocked the chimney off your lamp,--that made a crash all right. And
the lamp upset, and it is the kerosene drip, dripping from the table to
the floor. Girls who must have kerosene lamps to heat their curlers
