"Oh, the word on that last piece of stone turns out to be 'cave,' and when thinking the matter over I thought of the place Mark had entered after the porcupine, so I spotted the place before dark, and then quietly left the camp after dinner on a private exploring expedition. That man suddenly sprang upon me just before you so opportunely appeared on the scene," explained Tom.

"Then that's all right—you were followed from the camp; I was afraid they had placed a guard over that entrance," said Burton. "I branch off here, for I cannot enter the camp in this disguise; I want to use it again, and as a Fakir I do not wish to be seen near the camp; but I hope to turn up early in the—or rather this morning. I advise you to get all the rest you can, for I think I can promise you a very lively time before many hours are over."

As Burton went on alone, he muttered, "Yes, I must have all arrangements carefully made. I expect we shall have a dangerous tussle, for they are not the class of men to give in quietly."

"It's what I call a tall order, Burton," exclaimed Tom Ellison, who, with the Doctor, had been listening to the police officer's plan to raid the Cave of Hydas.

"I am glad you turned up before eight o'clock, Burton, for it would be difficult to enter the cave and find our way about without your guidance. It seems a likely place to get one's head cracked in the dark," remarked the Doctor.

"It would not be easy for you to get in, but had I been caught last night you would have found a clue to my whereabouts in the letter I gave you. However, we are all here yet, and I expect we shall get the better of Appoyas and his gang if our plans work out properly, and if they don't, then, well—look out for yourselves," said Burton, and he shrugged his shoulders.

"What led you to suspect Appoyas, who you say is supposed to be one the wealthiest and most respected men on the Salt Range, Burton?" asked the Doctor.

"Well, I saw him with that long brass-studded stick, and his general description answers to the tall man who fought the other two in the museum. Then I followed the goat-boy who got the message from the goat, and the boy handed the message to a man, and this man took it to Appoyas, and finally my suspicions were confirmed when I heard Appoyas addressed by name in the cave last night," explained Burton.
