dently the makings of a supply of bombs. "You captured their
artillery."

"They can make more," Ned replied.

"And the maps he found," Jimmie cried. "Maps showing how to blow up a
Gatun dam and a New York newspaper office. All marked out. Just like
lessons on blowing things up from a correspondence school."

Frank was all attention immediately. He had heard something like that
before that day, and asked a score of questions in a breath.

When the story of the drawings was told the boys gathered about Ned while
he pointed out the lines drawn in what purported to be a sketch of the
basement of the _Daily Planet_ building. Frank declared that the dots made
in the drawing were located exactly at steel and concrete foundation
points. The plan of destruction had evidently been prepared by some one
familiar with the structure.

"It strikes me," Frank said, after a moment's inspection of the drawings,
"that we'd better get out of here and reach a cable office. One of the
plotters was kind enough to tell me what they were about to do, and this

the third rock."

"But I don't understand this," Ned said. "Where have you boys been this
morning?"

"This morning," declared Frank. "It is most night now."

"I'll tell you," grinned Jack, "they went and got taken prisoners by a
martinet of a fellow and a dwarf, and I had to go and get them out. Say!
But you wait a second, and I'll produce my modest assistant."

He stepped to the edge of the jungle and whistled shrilly, and the next
moment a slender boy of perhaps fifteen stood by his side, gazing at the
group, now on the pavement of what had at one time been the court of the
temple, with something of fear in his dark eyes. He was dressed in clothes
which were much too large for him, and his manner indicated that he was
not at ease in the company o
