The man regarded one of their captors closely for a moment and then, turning to the girl asked, "Did you ever visit a madhouse?"
She looked up at him in quick understanding and with a horrified expression in her eyes. "That's it!" she cried.
"They have all the earmarks," he said. "Whites of the eyes showing all around the irises, hair growing stiffly erect from the scalp and low down upon the forehead—even their mannerisms and their carriage are those of maniacs."
The girl shuddered.
"Another thing about them," continued the Englishman, "that doesn't appear normal is that they are afraid of parrots and utterly fearless of lions."
"Yes," said the girl; "and did you notice that the birds seem utterly fearless of them—really seem to hold them in contempt? Have you any idea what language they speak?"
"No," said the man, "I have been trying to figure that out. It's not like any of the few native dialects of which I have any knowledge."
"It doesn't sound at all like the native language," said the girl, "but there is something familiar about it. You know, every now and then I feel that I am just on the verge of understanding what they are saying, or at least that somewhere I have heard their tongue before, but final recognition always eludes me."
"I doubt if you ever heard their language spoken," said the man. "These people must have lived in this out-of-the-way valley for ages and even if they had retained the original language of their ancestors without change, which is doubtful, it must be some tongue that is no longer spoken in the outer world."
At one point where a stream of water crossed the trail the party halted while the lions and the men drank. They motioned to their captives to drink too, and as Bertha Kircher and Smith-Oldwick, lying prone upon the ground drank from the clear, cool water of the rivulet, they were suddenly startled by the thunderous roar of a lion a short distance ahead of them. Instantly the lions with them set up a hideous response, moving restlessly to and fro with their eyes always either turned in the direction from which the roar had come or toward their masters, against whom the tawny beasts slunk. The men loosened the sabers in their scabbards, the weapons that had aroused Smith-Oldwick's curiosity as they had Tarzan's, and grasped their spears more firmly.
