"Wait!" I cried. "It's a monkey."
Carlos, too, was surprised at the spectacle. He declared that he had never heard of monkeys inhabiting the island.
"It must be tame monkey," he said.
The animal swung from a branch of the tree to that of the next, and soon disappeared over the edge of the cliff.
"Well then," declared Norris, "if he's tame, he's either got loose in town and wandered a long way off, or there are other people beside ourselves about here."
No one had anything to add to Norris' observations, and we continued our return journey, little thinking that we were destined to see that monkey again.
We presently came to where descent was possible; and when the brook finally came in our way, I found much interest in the spot where the waters flowed into the hole in the rocks.
"It seems a queer freak," I told Norris, "that it should make its way through the hill like that."
"It isn't the first time I have seen nature doing such stunts," he returned. "I guess volcanic action has had most to do with it."
