She took one of the white stone rings from her open palm. Then having taken a small mirror from her pocket, she drew the corner of the stone across it.
“Hurrah!” she shouted. “It’s real. It cuts glass. It’s a diamond.”
“Be still!” said Doris gripping her arm. “You’ll frighten the monkey away. I’m afraid that we have killed the goose that lays the golden egg.”
“Killed what?” Dot stared at her in surprise.
“Don’t you see,” said Doris, “what we might have done? If our monkey friend has found two rings in the last few days, who can say how many more treasures there are hidden where these rings were found?”
“Who indeed?”
“If only we could have followed him to the source of his treasure.”
“We can! We can!” exclaimed Dot, springing up. “There he goes now!”
The next instant they were following on the trail of the fleet-footed monkey. In no time at all Dot, surer of foot and more accustomed to rough travel in the tropics, was far in the lead of her cousin.
“We—we’ll lose him!” she panted.
