“Absolutely. But I have only the story of a couple of prospectors, one of whom has been an old-time opal miner in Australia. They are both intelligent men, and their story rang true.” “Please let’s hear all about it!” begged Charmian. “An undiscovered valley! How can it be undiscovered when these prospectors know about it? And opals! You’ve lured me away from glands for the present, Doctor. Give us the yarn!” [18] CHAPTER III THE PROSPECTOR’S STORY “WELL,” began Dr. Shonto reflectively, “Andy and I were in our camp on the North Fork of the Lizard, about two and a half miles from Lovejoy’s place.
