Ten minutes later, however, they caught sight of a fire light.
"That looks like it might be a camp," suggested Adrian.
They rode cautiously forward.
"It surely is," affirmed Donald a couple of minutes later. "We'd better dismount and do a little reconnoitering on foot."
The suggestion was immediately put into effect.
Leaving their horses tethered beneath a giant palm, which would serve as a landmark, the boys crept stealthily forward. In a few minutes they were near enough to see figures about the fire.
"They are evidently getting ready to pass the night," said Donald.
"Yes," from Adrian, "and there is another fire off yonder," and he pointed to the right.
"They are getting ready to post their pickets," explained Donald.
"Then we'd better get busy, Don. There must be some way of finding out where the army is going to stop."
