“But how are you going to do it?” asked Frank.
“We’ll search the island for him,” replied Will. “Come on, we’ll start now.”
Changing from their bathing suits to more conventional garments, the boys and girls at once began a tour of the island. But though it was not very large, there were inaccessible places, and it must have been in one of these that Prince hid during the day, for they neither saw, nor heard anything of him.
“We’ve got to set a trap!” exclaimed Will.
“How?” asked Grace.
“Well, evidently he’s been in the habit of coming around the tent to get scraps of food. We’ll leave plenty out to-night, and also some oats. Then we’ll watch, and when Prince comes I’ll catch him.”
The boys voted this plan a good one. They went over to Mr. Lagg’s store in the Gem to get a supply of fodder for the trap.
“A horse on the island!” exclaimed Mr. Lagg. So that’s the ghost; eh? Well, it’s very likely, but it sort of spoils the story;
“A ghostly ghost—a ghost in white
Appearing in the darkest night.
That it should prove a horse to be,
Most certainly amazes me.”
“Good!” exclaimed Will, with a laugh. “You are progressing, Mr. Lagg.”
