“This won’t do. Go and bring Frances back, Anne. You must be brave, girls, and not give way to your fears. I can’t and won’t allow myself to imagine for a minute that any such dreadful thing has happened to Ruth and Blanche. It’s evident that Frances furnished Blue Wolf with an idea as to where they may be, but we mustn’t take the way he ran off as a sign of the worst. It may prove to be just the opposite. My advice to all of you is to sit down quietly, and keep your minds free of horrors.”
Miss Drexal had taken hold of the situation just in time to avert a wholesale collapse. When Anne returned, piloting a Frances whose drawn, tear-stained face bore small resemblance to her usual genial countenance, the others had followed the Guardian’s example and reseated themselves about the fire. None, however, had the will to talk. They sat in hushed silence and waited, listening for the first sound from the forest that would herald the return of the guide, hoping with that intensity of “hope deferred which maketh the heart sick” that he would not return alone.
Meanwhile, Blue Wolf was tearing along through the black night utterly impervious to the rough course he had elected to travel. Day or night, the forest itself had no terrors for him. It was the information supplied by Frances that now held him in a fearsome grip and lent wings to his tireless feet. The faltering opinion that Betty had voiced was partially his own. He knew of only one other thing that might have happened, and on it he based his hope of finding both girls alive. With the unerring faculty of the Indian for traveling sure-footedly the most difficult territory in the dark, he crashed his speeding way through brush and bramble, never halting for an instant.
At the break-neck pace he was going, it did not take him long to reach the spot in the woods where the ledge was situated. Far from investigating it from the top, he steered straight for the hollow below. Reaching it, he delayed only long enough to light a fresh torch and stamp out the old, then went confidently forward. Training his light low, his first find was the dead tree lying in the midst of its shattered branches. Up and down its length he moved, his eyes bent to the earth. With a satisfied “Ugh!” he finally left it. Next he hurried to a spot above which the flicker of his now upraised torch showed an out-cropping rocky ledge. Straight to it he loped. Directly under it lay a huge boulder. All around it quantities of fresh earth and splintered rock told their own story. Here his investigations grew more minute. He dropped on all fours and crawled round and round the boulder, his gaze never leaving its base. Finally springing up, he laid his torch on a nearby stone and began a veritable tussle with the rock itself. Exerting his full strength, he tried to move it. It refused to budge. Over and over again he attacked it, from various angles. It was there to stay.
Panting a little, he drew back from it, and lifting his voice in a prolonged howl. Again and again the weird, mournful cry filled the surrounding silence. Still it provoked no answer, save a sighing protest from the trees, or the sleepy twitter of a bird, rudely disturbed from sleep. Blue Wolf, however, was not to be thus dismayed. He had tried one thing, and that had failed. He still had another resource. His second torch on the point of failing, he stoically lighted another, and was soon racing away from the hollow.
Deeper into the woods he went, following a comparatively straight line from the ledge. Not more than a quarter of a mile from the ledge he stopped again,—this time at the bottom of a fairly deep ditch that had once been the bed of a stream. It was now fairly dry, as there had been little rain during the summer. Its sloping sides were thickly covered with green bushes, huge broad-leafed weeds and stunted trees. Traveling the bottom of the dried-out water-course for a few yards, the guide plunged straight into a thicket of bushes, breaking them down in his haste. Suddenly he bent double, and disappeared into the greater darkness of a good-sized gap in the slope, well concealed by the luxuriant screen of living green.
Ruth Garnier had been wholly correct in thinking that there was a second entrance to the underground passage which she and Blanche had essayed to follow. Born and raised in the vicinity of Vermilion Lake, Blue Wolf had explored this very passage when a boy. According to his grandfather, the Cheyenne warrior chief, he had more than once used it as a means of escape in times of peril. Undoubtedly it had existed long before the old chief’s day. He had believed it to be the work of his ancestors, excavated when the Indians claimed the vast northern forests as their own.
At first mention of the ledge as near the point where the two girls had disappeared, Blue Wolf had pricked up his ears. Learning of the rock slide, he had been visited by the fear that Blanche and Ruth might have been standing under the ledge when it occurred. It was more than possible that they had seen the entrance to the cave and gone close to it to examine it. It was this that had caused him to shout and race off to the scene. He was in deadly fear that he would there discover only their crushed, lifeless bodies. He knew of no other spot on the island where self-reliant Ruth was likely to have come to grief. She was too good a woodsman to be merely lost.
When a careful search revealed nothing of the sort, his one other theory, that they might have entered the cave just before the rock fell, seemed in keeping with his discovery that the entrance to the cave had been effectually sealed by the boulder. Believing them to be on the other side of it, he had tried to roll it away. Failing he had begun to shout in the hope of making them hear him. This proving also fruitless, he had promptly sought the other end of the passage, determined to investigate every inch of it.
