“I saw them again,” he gasped.

“Saw who?”

“Those spooks. They are right back of us.”

“I’m glad you did. It’s some of our boys, for sure. Hullo, fellows!” hailed Ned. But no answer was vouchsafed. Ned began not to like the look of things a little bit.

For a long time the boys tried to find their way out of the Pyramid, but without success. Finally they came to a halt and exchanged dismayed glances.

“We might as well face the truth,” said Ned in sober tones; “we’re lost.”

“That’s right,” agreed Herc in melancholy fashion. “I wish we’d stayed outside.”

“Maybe we can get back to the burial chamber,” suggested Ned, after a while. The boys were then standing in a passageway into which they had blundered in the hope that it might lead to daylight.

“I doubt it. I’ve not the remotest idea of where it is, and this Pyramid is simply honeycombed with passages.”

“The guide said nobody knew all about it. Maybe we are in one of those passages that haven’t been explored yet.”
