On the following evening, as soon as we had finished dinner, Sydney led me, as on the previous occasion, through his study and into the library; but we did not wait here, for going up to a curtain at one corner, he pushed it aside, and opening a door led me into a room beyond. This room did not seem to be lighted in any way from the outside, but an electric light, the first I ever saw in a private house, cast a strong glare over the apartment. As soon as we entered, my companion touched a handle and a shade passed over the light; the effect was pleasant and restful. Except in one recess which was curtained off from the rest of the room, there were few signs of comfort. I could not help fancying that I had suddenly entered a scientific laboratory; the walls of the room were covered with mechanical apparatus of various kinds, and with shelves that contained rows of bottles, tubes, and other chemical appliances. "This," said Sydney, "is my workshop, where for years I have been busy trying experiments on nature by the assistance of knowledge gained through the development of our sixth sense. There is no doubt whatever that when men once begin to understand the uses of this latent power, existence will be revolutionized entirely. The world as it is now will cease to exist, and there will be a new heaven and a new earth. But," he continued after a pause, "I fear the time is not yet come; for so awfully will man’s power be increased, that unless our natures are at the same time purified and perfected, existence here under such a reversal of conditions would be in truth hell itself. "Fortunately, however, the power of using this sense is greatly dependent on the lives of the persons employing it. If a man has not learned to curb his passions and keep his body under control, he will make little progress, for the subjugation of the body is essential to success. The weakness of my own nature has, alas! too often caused me to break down at the very moment of seeming victory. If only a man were perfectly unselfish, pure, and free from pride, he could without the aid of science and without seeming effort control the forces of nature. Such a One has been on earth, and we know the result. Such power may be given when man has learnt to follow His example. But as man becomes conscious of his new powers we may expect a terrible time of transition, for with the possession of free will each added gift means added force to evil as well as to good, even as I was saying last night with regard to the gift of alcohol.
