While old Lady Poole leant back in her chair with closed eyes and a gentle smile playing about her lips, enjoying, in fact, a short and well-earned nap, the great scientist's passionate voice boomed out into the room and held Marjorie fascinated. She leant forward, listening to him with strained attention--her lips a little parted, her face alight with interest, with eagerness. "You want to hear, dearest," he said, "you want to hear? And to whom would I rather tell my news? At whose feet would I rather lay the results of all I am and have done? Listen! Even to you I cannot tell everything. Even to you I cannot give the full results of the problems I have been working at for so many years. But I can tell you enough to hold your attention, to interest you, as you have never been interested before." He began to speak very slowly. "I have done something at last, after years of patient working and thought, which it is not too much to say will revolutionize the whole of modern life--will revolutionize the whole of life, indeed, as it has never been changed before. All the other things I have done and made, all the results of my scientific work have been but off-shoots of this great central idea, which has been mine since I first began. The other things that have won me fame and fortune were discovered upon the way towards the central object of my life. And now, at last, I find myself in full possession of the truth of all my theories. In a month or two from now my work will be perfected, then the whole world will know what I have done. And the whole world will tremble, and there will be fear and wonder in the minds of men and women, and they will look at each other as if they recognized that humanity at last was waking out of a sleep and a dream." "Is it so marvellous as all that?" she said almost in a whisper, awed by the earnestness of his manner. "I am no maker of phrases," he replied, "nor am I eloquent. I cannot tell you how marvellous it is. The one great citadel against which human ingenuity and time have beaten in vain since our first forefathers, is stormed at last! In my hands will shortly be the keys of the human soul. No man or woman will have a secret from me. The whole relation of society will be changed utterly." "What is it? What is it?" she asked with a light in her eyes. "Have you done what mother said in jest? Have you indeed finally conquered the air?" He waved his hand with a scornful gesture.
