Anderson, after reflecting for a moment, apologised for his peremptory words, and agreed to stand by night and day, with fires banked, until I, and all whom I could prevail upon to return with me, got back to his vessel. There was no danger of his running short of coal. A ship that was practically an ocean liner in coal ballast would be a considerable time in burning out her own cargo. But he insisted on a large money payment in advance. I had foolishly mentioned that I had a little over £5000 in gold. This he claimed on the plea that "in duty to himself"—a favourite phrase of his—he could not accept less. But I think his sense of duty was limited only by the fact that I had hardly another penny in the world. Under the circumstances he might have waived all remuneration. As he was firm, and as I had no time to haggle, I agreed to give him the money. Our bargain was only completed when Brande returned to the deck.
It was strange that on an island like that on which we were landing there should be a regular army of natives waiting to assist us with our baggage, and the saddled horses which were in readiness were out of place in a primeval wilderness. An Englishman came forward, and, saluting Brande, said all was ready for the start to the hills. This explained the puzzle. An advance agent had made everything comfortable. For Brande, his sister, and Miss Metford the best appointed horses were selected. I, as physician to the chief, had one. The main body had to make the journey on foot, which they did by very easy stages, owing to the heat and the primitive track which formed the only road. Their journey was not very long—perhaps ten miles in a direct line.
Mounted as we were, it was often necessary to stoop to escape the dense masses of parasitic growth which hung in green festoons from every branch of the trees on either side. Under this thick shade all the riotous vegetation of the tropics had fought for life and struggled for light and air till the wealth of their luxuriant death had carpeted the underwood with a thick deposit of steaming foliage. As we ascended the height, every mile in distance brought changes in the botanical growths, which might have passed unnoticed by the ordinary observer or ignorant pioneer. All were noted and commented on by Brande, whose eye was still as keen as his brain had once been brilliant. His usual staid demeanour changed suddenly. He romped ahead of us like a schoolboy out for a holiday. Unlike a schoolboy, however, he was always seeking new items of knowledge and conveying them to us with unaffected pleasure. He was more like a master who had found new ground and new material for his class. Natalie gave herself up like him to this enjoyment of the moment. Edith Metford and I partly caught the glamour of their infectious good-humour. But with both of us it was tempered by the knowledge of what was in store.
When we arrived at our destination we dismounted, at Brande's request, and tied our horses to convenient branches. He went forward, and, pushing aside the underwood with both hands, motioned to us to follow him till he stopped on a ledge of rock which overtopped a hollow in the mountain. The gorge below was the most beautiful glade I ever looked upon.
It was a paradise of foliage. Here and there a fallen tree had formed a picturesque bridge over the mountain stream which meandered through it. Far down below there was a waterfall, where gorgeous tree-ferns rose in natural bowers, while others further still leant over the lotus-covered stream, their giant leaves trailing in the slow-moving current. Tangled masses of bracken rioted in wild abundance over a velvety green sod, overshadowed by waving magnolias. Through the trees bright-plumaged birds were flitting from branch to branch in songless flight, flashing their brilliant colours through the sunny leaves. In places the water splashed over moss-grown rocks into deep pools. Every drifting spray of cloud threw over the dell a new light, deepening the shadows under the great ferns.
It was here in this glorious fairyland; here upon this island, where before us no white foot had ever trod; whose nameless people represented the simplest types of human existence, that Herbert Brande was to put his devilish experiment to the proof. I marvelled that he should have selected so fair a spot for so terrible a purpose. But the papers which I found later amongst the man's effects on the Esmeralda explain much that was then incomprehensible to me.
Our camp was quickly formed, and our life was outwardly as happy as if we had been an ordinary company of tourists. I say outwardly, because, while we walked and climbed and collected specimens of botanical or geological interest, there remained that latent dread which always followed us, and dominated the most frivolous of our people, on all of whom a new solemnity had fallen. For myself, the fact that the hour of trial for my own experiment was daily drawing closer and more inevitable, was sufficient to account for my constant and extreme anxiety.
Brande joined none of our excursions. He was always at work in his improvised laboratory. The boxes of material which had been brought from the ship nearly filled it from floor to roof, and from the speed with which these were emptied, it was evident that their contents had been systematised before shipment. In place of the varied collection of substances there grew up within the room a cone of compound matter in which all were blended. This cone was smaller, Brande admitted, than what he had intended. The supply of subordinate fulminates, though several times greater than what was required, proved to be considerably short. But as he had allowed himself a large margin—everything being on a scale far exceeding the minimum which his calculations had pointed to as sufficient—this deficiency did not cause him more than a temporary annoyance. So he worked on.
When we had been three weeks on the island I found the suspense greater than I could bear. The crisis was at hand, and my heart failed me. I determined to make a last appeal to Natalie, to fly with me to the ship. Edith Metford would accompany us. The rest might take the risk to which they had consented.
I found Natalie standing on the high rock whence the most lovely view of the dell could be obtained, and as I approached her silently she was not aware of my presence until I laid my hand on her shoulder.
