"My third plan seems to me the most feasible. You all saw a number of large, heavy boxes lowered into the hold before we sailed. I know you did, because you asked me what they contained and commented upon the large letter 'H' which was painted upon each box. These boxes contain the various parts of a hydro-aeroplane. I purpose assembling this upon the strip of beach described in Bowen's manuscript--the beach where he found the dead body of the apelike man--provided there is sufficient space above high water; otherwise we shall have to assemble it on deck and lower it over the side. After it is assembled, I shall carry tackle and ropes to the cliff-top, and then it will be comparatively simple to hoist the search-party and its supplies in safety. Or I can make a sufficient number of trips to land the entire party in the valley beyond the barrier; all will depend, of course, upon what my first reconnaissance reveals."
That afternoon we steamed slowly along the face of Caprona's towering barrier.
"You see now," remarked Billings as we craned our necks to scan the summit thousands of feet above us, "how futile it would have been to waste our time in working out details of a plan to surmount those." And he jerked his thumb toward the cliffs.
"It would take weeks, possibly months, to construct a ladder to the top. I had no conception of their formidable height.
Our mortar would not carry a line halfway to the crest of the lowest point. There is no use discussing any plan other than the hydro-aeroplane. We'll find the beach and get busy."
Late the following morning the lookout announced that he could discern surf about a mile ahead; and as we approached, we all saw the line of breakers broken by a long sweep of rolling surf upon a narrow beach. The launch was lowered, and five of us made a landing, getting a good ducking in the ice-cold waters in the doing of it; but we were rewarded by the finding of the clean-picked bones of what might have been the skeleton of a high order of ape or a very low order of man, lying close to the base of the cliff. Billings was satisfied, as were the rest of us, that this was the beach mentioned by Bowen, and we further found that there was ample room to assemble the sea-plane.
Billings, having arrived at a decision, lost no time in acting, with the result that before mid-afternoon we had landed all the large boxes marked "H" upon the beach, and were busily engaged in opening them. Two days later the plane was assembled and tuned. We loaded tackles and ropes, water, food and ammunition in it, and then we each implored Billings to let us be the one to accompany him. But he would take no one.
That was Billings; if there was any especially difficult or dangerous work to be done, that one man could do, Billings always did it himself. If he needed assistance, he never called for volunteers--just selected the man or men he considered best qualified for the duty. He said that he considered the principles underlying all volunteer service fundamentally wrong, and that it seemed to him that calling for volunteers reflected upon the courage and loyalty of the entire command.
We rolled the plane down to the water's edge, and Billings mounted the pilot's seat. There was a moment's delay as he assured himself that he had everything necessary. Jimmy Hollis went over his armament and ammunition to see that nothing had been omitted. Besides pistol and rifle, there was the machine-gun mounted in front of him on the plane, and ammunition for all three. Bowen's account of the terrors of Caspak had impressed us all with the necessity for proper means of defense.
At last all was ready. The motor was started, and we pushed the plane out into the surf. A moment later, and she was skimming seaward. Gently she rose from the surface of the water, executed a wide spiral as she mounted rapidly, circled once far above us and then disappeared over the crest of the cliffs. We all stood silent and expectant, our eyes glued upon the towering summit above us. Hollis, who was now in command, consulted his wrist-watch at frequent intervals.
"Gad," exclaimed Short, "we ought to be hearing from him pretty soon!"
Hollis laughed nervously. "He's been gone only ten minutes," he announced.
"Seems like an hour," snapped Short. "What's that? Did you hear that? He's firing! It's the machine-gun! Oh, Lord; and here we are as helpless as a lot of old ladies ten thousand miles away! We can't do a thing. We don't know what's happening.
Why didn't he let one of us go with him?"
Yes, it was the machine-gun. We would hear it distinctly for at least a minute. Then came silence. That was two weeks ago.
We have had no sign nor signal from Tom Billings since.
