"He might like to try a motor, I said," replied Cora. "They say that Jim Peters tries everything on Cedar Lake, even to running a shooting gallery. But see! He is reading a letter! Where ever did he get a letter on this barren island?"
"Maybe he carries the mail for the ghost," said Hazel, with a laugh.
CHAPTER IX
JACK AND CORA
"Cora, where is your ring?"
The sister looked at her finger. "Oh Jack," she replied, "I will get it—but not just now. Why?"
"I thought you always wore that ring when you put on your frills, and I haven't seen you so dressed up since you came to camp. Somehow, Cora, I feared you might have lost it."
"I did," she said simply.
"Your new diamond!"
"Yes, but I feel sure of finding it. Now, Jackie dear, please don't cross question me. I shouldn't have taken it off, but I did, so and that is how I came to lose it. But I want to tell you something while we are alone. I saw the ghost of Fern Island to-day."
