your aeroplane. It only remains to shake your hands, both,
_amigos_, and wish you every good fortune your valor deserves."

They squeezed the hand of the fine old Colombian gentleman with
vigor. Never would Andy forget how he had spoken concerning his interest
in the sacred duty that had brought the son of the missing aeronaut to
his country.

Frank had given strict orders that none of the crew should go ashore,
and also that no strangers be permitted to board the craft while they
lay there at the old wooden wharf.

"But," said Andy, when they were speaking about this matter, as
preparations began to leave the port, "that hasn't prevented the crew
from holding an animated confab with those ashore. There has been a
constant jabbering and laughing between our fellows and those others."

"Yes," admitted Frank, "and I've seen several of the crew talking
mysteriously with some of those chaps. I wish now the señor had thought
to indicate which was the secret agent of the revolutionists he saw on
the dock. But all the same I've marked the two fellows I suspect, and
I'm going to keep a close eye on Enrique, and the little fellow with the
quick motions we call 'Cospita,' because he's forever ejaculating like
that."

"And if you find out that they're meddling with the boxes?" asked Andy.

"H'm! I guess it'll be a bad day for Enrique and the jumping-jack,
that's all," laughed his cousin. "But there goes the cable, and it looks
like we might be off at last."
