"Well, it's the same with the girls," muttered Holman. "The stillness of the place has brought their ordinary conversational tone down to a whisper."
Leith lurched across and interrupted our conversation. "Get the boys going, Mr. Verslun," he said. "We want to cross the Vermilion Pit while the light is good, and it is hard going from here on."
We started forward up the boulder-strewn slope, and with each step the difficulties of the ascent became greater. I took an axe and helped Soma chop a path which would make it easier for the two sisters, but no matter what amount of trouble we took, they found it a difficult matter to follow. Once, goaded into fury by Leith's attempts to hurry the girls when Holman was assisting them over a particularly rough stretch, I turned upon the old scientist who was puffing along with the natives in the lead.
The half-insane ancient heard my outburst to the end, staring at me through the thick lenses of his glasses as if I was some new kind of a bug whose appearance he wished to implant firmly within his mind.
"Science calls for sacrifices," he squeaked. "If my daughters are heroines who wish to share my hardships in the pursuit of information that will be of great benefit to the world, I fail to see what it has to do with you, sir!"
"But they have no interest in your silly discoveries," I cried. "They are doing this infernal tramp to look after you. Do you hear?"
"Confound you, sir!" he screamed. "Mind your own business and don't interfere with mine!"
I choked down my wrath as Leith came crashing through from the rear, and the old egoist, flushed and ruffled, dropped back to meet him, evidently convinced of my insanity through my inability to appreciate his efforts to prove that the skulls of long-dead Polynesians possessed peculiar formations they were foreign to the islanders of the present day.
It was about four o'clock in the afternoon when we began to draw near the Vermilion Pit which Leith had mentioned when he had urged haste at the midday luncheon. The surroundings became more strange and mysterious with each step we took. The basalt peaks that we had noticed from the deck of The Waif were now quite close to us, and they seemed to move in upon us from both sides. The trees and lianas became less numerous, and the black rocks came toward us in a sinister manner that conjured up thoughts of a dead something toward which the encircling ridges were guiding us like the arms of a corral. The place was fear-inspiring. It had the unearthly appearance that made the imaginative minds of the ancients people the silent woods with devils and dryads. The soft moaning of the Pacific was barred out by the leafy barriers, and we walked in a silence that was tremendous. The ticking of our watches sounded to our strained ears like the blows of a hammer, and once, when the Professor sneezed mightily, Miss Barbara gave a scream of fear before she realized what had caused the noise.
The ascent became still more difficult. The natives puffed under their loads, and Holman rushed angrily to the front and demanded a halt on behalf of the girls struggling in the rear. During the few minutes that Leith grudgingly allowed them in which to recover their breath, the youngster hurried up to the spot where I was busy fixing the loads of the natives, and in a nervous whisper he asked my opinion of the route.
