“Look here, you fellows!” Jimmie answered darting back into the temple. “There’s a great white rock on the cliff back of the temple. It looks like one of these memorial stones aldermen put their names on when they build a city hall. All we have to do to signal the aeroplanes is to put red caps over our searchlights and turn them on that cliff. They will make a circle of fire there that will look like the round, red face of a harvest moon.”
“That’s right!” agreed Carl.
“A very good idea!” Sam added.
“I’ve been trying to find a way to get up on the roof,” Jimmie continued, “but can’t find one. You see,” he went on, “we can operate our searchlights better from the top of the temple.”
“We’ll have to find a way to get up there!” Sam insisted.
“Unless we can make the illumination on the cliff through the hole in the roof,” Jimmie proposed.
“And that’s another good proposition!” Sam agreed.
“And so,” laughed Carl, “the stage is set and the actors are in the wings, and I’m going to crawl into one of the bunks in the west room and go to sleep.”
“You go, too, Jimmie,” Sam advised. “I’ll wake you up if anything happens. I can get my rest later on.”
The boys were not slow in accepting the invitation, and in a very short time were sound asleep. It would be time for the Bertha and Louise to show directly, and so Sam placed the red caps over the lamps of two of the electrics and sat where he could throw the rays through the break in the roof. Curious to know if the result was exactly as he anticipated, he finally propped one of the lights in position on the floor and went out to the entrance to look up at the rock.
