Before long they began to grow hungry, and stopped their search long enough to get a lunch of berries and cold fish, washed down with water from one of the bamboo stems.
"This is a great way to carry water," was Dave's comment. "It keeps it very sweet."
"So it does, Dave," said the doctor. "But the water is bound to evaporate very rapidly."
The lunch over, they resumed their journey. They had put far out to sea on one side of the island. Now they returned, to put out on the opposite side.
They were within three hundred feet of the island when Doctor Barrell set up a cry of warning.
"Stop! Do not land!"
"What's the matter, doctor?" came from the captain. "We were not going to land. We are bound for the other side of the island."
"I saw some persons moving behind yonder bushes and rocks," went on the man of science.
"Saw somebody?" ejaculated Dave.
"Yes."
