For two days we followed the winding contours of the valley, every hour rising higher and higher into the mountain range, whose arms almost imperceptibly and inevitably closed in behind us until we all had the feeling that we were in a giant's grip. The wind increased daily, blowing in gusts from the heart of the range, but it did not trouble us as the desert wind, as there was little dust to obscure our view. It did, however, add to the difficulties of steering and our vehicles tended to yaw from side to side so that one wearied at the handles and muscles craved relief from the buffeting, which went on hour after hour.
It was growing steadily colder too, though the sun shone as regularly as hitherto; this did not bother us at first but we were then aware, during our frequent halts, that the breeze was a chilly one and we were beginning to feel the benefit of the sheepskin-lined coats which was one of Scarsdale's strange-seeming requisitions for the expedition's stores. The way twisted and wound upwards and for most of the time we were steering the tractors at half-speed through mazes of gigantic boulders and among formations of weirdly striated rock.
But there had been no major difficulties; the tractors were standing up well to the wear and tear of this difficult going and, most important of all, there had so far been no impossible places; no doubt due to Scarsdale's detailed surveying of the route on his previous journeyings. If there had been one impassable section then that would have made the Expedition untenable; apart from our using the tractors as mobile bases, there was the sheer impossibility of transporting the masses of stores and equipment along these miles of pitiless moraine.
The territory through which we were advancing was quite featureless; black rock; boulders; stunted trees; above, a perpetually blue sky; ahead, the eternal probe of the restless wind in one's teeth and the jumble of rocks which indicated the next bend.
We were too close in now to see what peaks lay ahead and so far as one was aware we were not high enough for snow. Scarsdale still continued in his mysterious and inscrutable way. Though his charts, log books and tables of weird hieroglyphs multiplied on the chart-table in the command vehicle at night, he gave no detailed hints of what we might soon expect.
We had been several days on our journey to the plateau when I myself broached the matter one evening; he shook his head, with an enigmatic smile.
'We are not close enough yet,' was all he would say. 'Time enough when we are within the Galleries.'
He had with him a translation of the blasphemous book. The Ethics of Ygor, which had been typed on ordinary foolscap sheets and he would be lost for hours in its study most evenings, the smoke from his pipe curling upwards vertically in the still air of the tractor. While in the desert we had kept within the machines whenever we stopped. There was good reason for this, of course; the tractors were air- conditioned and the sand and grit constantly blown about made eating and conversation in the open air a misery.
But here just the opposite rule obtained. Though the air was cold and the wind blew chill, whenever Scarsdale called a halt over his radio link and all three vehicles drew into a rough laager, we all of us, without anyone ever putting it into words, foregathered in the open air, lit fires and cooked our food. Huddled in our sheepskin jackets and hoarding our precious gatherings of wood we drank our nightly tea-ration and made the mountains echo with our animated talk.
Van Damm in particular made his own attitude plain; I could read it well enough on his face, though he never put the feeling into words. We were whistling in the dark, his taut features said to me every night, as he gazed apprehensively around him at the dark rock whose jumbled surface was lit by the flickering flames of our necessarily feeble fires. We all felt it now; the mountains were closing in on us and inside the tractors the feeling was only emphasised. When we were asleep this did not matter; but until then we preferred to chat among ourselves; lounge outside; braving the wind, downing the hot sweet tea in thirsty gulps and constantly scanning what little we could see of our surroundings. But I noticed that none of us strayed outside the triangle of tractors, in which the fires formed the cheerful focal points. So far as we knew there was no wild-life in the mountains and no dangerous crevasses into which we might fall; but still we did not wander.
Day was a different matter but even there I noticed my companions rarely ventured more than a hundred yards or so from our established camp. The only exception was Scarsdale; he was, of course, as I knew, absolutely fearless and sometimes at night he would disappear for as long as half an hour at a time, on some mysterious expedition of his own. On the first occasion this happened I was consumed with alarm and was about to call my companions when he emerged from the darkness, the small round glow of his pipe illuminating his bearded features. His notebook was in his hand and there was an excited look in his eyes, but I had learned my lesson by now and I did not venture to question him.
But I remembered that he had traversed this way alone and with none of the advantages that we five currently enjoyed and once more I marvelled at the tenacity and endurance of the man; he had moral integrity as well as physical endurance and there were times as the weeks lengthened, that I came near to adulation of our leader. The Great Northern Expedition was certainly the highest point in my wanderings in a life not entirely devoted to mundane things, and even though the Professor's purpose remained shrouded in obscurity I felt I would have followed him almost anywhere he chose to lead us.
We were four days traversing the gulley; towards the end the scree and the shattered boulders which lay like great shards of rock fallen from a region as remote as the moon, made progress maddeningly slow. But the tractors behaved extraordinarily well; I think each of us, underneath, harboured a fear that the motors of the machines might overheat or that breakage of vital components would strand us here. For that reason those of us who were driving nursed the vehicles along.
It was unlikely, I reasoned, that all three of the machines would break down, but stranger things had happened; I cast my mind back to my own adventures in the Arizona Desert and Crosby Patterson's terrible and unique fate and pictured what might happen to us were we thrown on our own resources and have to return on foot. That outcome was unthinkable and I preferred instead to concentrate on my immediate duties.
I was pleased, during the second day, when Scarsdale announced to me that he would himself take over the controls of the command tractor. This left me for other duties, not least those-of my photographic recording activities and I secured one of the best sequences of the entire movie record the following afternoon, with my series of swooping pans and tracking shots from the windows of our vehicle, as we crawled inexorably into the higher plateau of the Black Mountains.
It was a fearsome landscape into which we were slowly edging our way and Scarsdale had still not revealed to us our exact destination or what our role would be; he sat now, bracing himself in the padded seat, his great hands firm and steady on the levers, gently coaxing the power under his hands. The command vehicle would shudder, hang sicken- ingly on the edge of some unseen rock shelf and then with a lurching motion, step quietly into a higher plane and then proceed again smoothly enough until the next obstacle was met.
The mountain walls ahead now completely blotted out the sky and for the last day or so the sun had disappeared; everything around us was in purple shadow and then we came out again round a shoulder of hill and a high sun, spilling in from behind us somewhere cast a pallid glimmer on the blackness of the shoulder of mountain beyond. Nowhere was there any sparkle of light or any relief in the sombre shade of these oppressive peaks; the wind still blew steadily but seemed to have lost some of its sting and the noise of our motors thrown back from the rocky walls each side of us seemed less sacrilegious.
