“They certainly do,” Marjorie agreed. “But let’s keep looking. We might find some really valuable ones which we could sell to collectors for a lot of money.”
For the next few minutes they were very busy pushing and shoving at the rocks, upturning some and giving up others that were too heavy to budge.
Finally they came across one huge stone that seemed to be imbedded in the sand. Marjorie knew that even with Judy’s help she couldn’t move it, and she was just about to crawl by it when she saw something.
“Judy,” she cried excitedly. “Come here, quickly. Doesn’t it look as though someone had been digging around this rock a little while ago?”
Judy scrambled to her feet and joined Marjorie. “You’re right,” she said. “Some one has been digging here. I’ll bet whoever it was buried something under that rock.” She flopped down on her knees beside Marjorie and together the girls began to dig frantically with their fingers.
And then Marjorie’s sharp eyes caught a glimpse of something that glittered in the sunlight. “Diamonds,” she gasped. “Judy, help me. Let’s see if we can’t inch the rock up a little so we can see better. Oh, wouldn’t it be wonderful if there was real honest-to-goodness treasure buried here?”
Judy, tugging at the heavy rock, could only pant, “There. Now we’ve got it!”
They both fell to digging with renewed vigor, and in another second Marjorie could see that the glittering object was only a dark green glass bottle.
“Oh, for Pete’s sake,” she moaned disappointedly. “And I thought we were at last going to find the buried treasure.” Crossly she yanked the bottle out of the warm sand and raised her arm to toss it into the lake.
“Wait a minute!” cried Judy, grabbing her arm just in time. “There’s something in that bottle, Marjorie. When you held it up in the sunlight I could see right through the dark green glass.”
