"I shouldn't wonder. Let's go and see."

"Let's fill up this hole first and put the skull back to fool somebody else."

"All right," and Jack hastily tossed the dirt back into the hole, and replaced the little white skull.

"Somebody is coming this way! Let's hide," and Dolly and Jack quickly whisked themselves behind a clump of trees.

Guy Holmes and Maisie Norris came along and they spied the white skull which Jack had left placed rather more conspicuously than he had found it.

"Oh, look at that!" cried Guy, and Maisie exclaimed, "This is the right place, of course! We've struck it at last! That pirate flag was just to fool us. Hooray! let's dig!"

Dolly and Jack could scarcely keep from laughing aloud as they saw the newcomers digging desperately in the very spot they had dug themselves.

At last Jack beckoned to Dolly and they softly glided away without letting the others know of their presence.

"Now we want to find where it really is," whispered Jack as soon as they were out of hearing of the others. "I say, this is a great game! and we've learned something from those people. The spot marked with a pirate flag is not the right one! When we find that, there is no use of digging."

The pair went on, prospecting for a likely place to dig. There were so many trees and shrubs, that often there would be no view of any of the other seekers. And then again they would come across groups of two or three, or perhaps one alone digging desperately or looking disappointed at a failure.
