"And you think you've got a key to it?" asked Frank.
"I've got a key to something," was the reply.
Frank opened his lips to make some remark, but Ned laid a hand on his arm and drew closer to him so that a low voice might be heard, at the same time motioning to Pat to remain quiet.
"Now, don't move, or turn to look," Ned said, "but in a few seconds, after I have turned away, look, casually, toward the great balete tree which rises above the jungle straight to the south."
Ned turned away directly and faced the jungle to the north.
"What do you see?" he asked, turning toward the boys again but not looking at them.
"Monkeys wiggling in the creepers," Frank said.
"Filipinos," answered Pat.
"How many?" asked Ned.
"Well," replied Pat, "I thought I saw two, but I guess there is only one. We've got to get him," he added.
