Jimmie followed his chum, and the two searched the entire system of tunnels known to them without discovering any trace of the missing man.
“That’s a nice thing!” Jimmie declared. “We probably passed him somewhere on our way back to the temple. By this time he’s off over the hills, making signals for some one to come and help put us to the bad.”
“I’m afraid you’re right!” replied Sam.
The boys ate their sandwiches and discussed plans and prospects, listening in the meantime for indications of the two missing men. Several times they thought they heard soft footsteps in the apartments opening from the corridor, but in each case investigation revealed nothing.
It was a long afternoon, but finally the sun disappeared over the ridge to the west of the little lake and the boys began considering the advisability of making ready to signal to the Louise and Bertha.
“They will surely be here?” said Carl hopefully.
“I am certain of it!” answered Sam.
“Then we’d better be getting something on top of the temple to make a light,” advised Jimmie. “If I had Miguel by the neck, he’d bring out his red and blue lights before he took another breath!” he added.
“Perhaps we can find the lights,” suggested Sam.
This idea being very much to the point, the boys scattered themselves over the three apartments and searched diligently for the lamps or candles which had been used by Miguel on the previous night.
