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.
