The three other girls calling a blithe good-bye to Miss Carroll, the quartette left the patio with an alacrity that betokened their eagerness for the proposed walk.

“I didn’t care to tell her about thinking I saw the picture move,” confessed Patsy. “As it is I’m in for swallowing one of those fat nerve capsules that Auntie always keeps on hand. I need it about as much as a bird needs a hat. We’ll have to walk fairly fast to get to the beach and back by luncheon time, girls. We’ll lay the book on the sand, then watch from the bath house windows to see what happens.”

“I hope our wood nymph comes along and finds it to-day,” commented Mabel. “Still she might not go near the beach for several days. After all, there’s only a chance that she’ll see it and pick it up.”

“I have an idea she goes to the beach every day,” said Beatrice. “She may be as curious about us as we are about her. She may be so shy, though, that she won’t come near us, even if she does read our note.”

Thus discussing the object of their little scheme, the Wayfarers forged ahead at a swinging pace. Soon they had left the highway and were on the narrow, white, palm-lined road to the beach, talking busily as they went. Once in the jungle four pairs of eyes kept up an alert watch on both sides of the road in the hope of spying the elusive wood nymph.

She caught her breath sharply, … had the man in the picture actually moved?

They came at last to the beach, however, without having seen any signs of their quarry. After they had gone through the little ceremony of placing the book on the spot on the sands from which the other book had disappeared, they went over to the bath house and, entering, eagerly watched from one of its windows.

After lingering there for half an hour, during which period the fateful book remained exactly where it had been laid, they gave up the vigil for that day and reluctantly started on the homeward hike.
