On the Embankment I returned to a full sense of my position in space. The river ran beneath me, cold and dark. I leaned over the stone balustrade and stared at the dark forms of barges. Yes, it was true enough that I had not realized that the germ would keep Mr. Annot alive indefinitely. Sarakoff's significant whistle that morning came to my mind, and I saw that I had been guilty of singular denseness in not understanding its meaning. And now old Annot would live on and on, year after year. Was I glad? It is impossible to say. It was that expression in the old man's face that dominated me. I tried to think it out. It had been a triumphant look; and more than that ... a triumphant _toothless_ look. Was that the solution? I reflected that triumph is an expression that belongs to youth, to young things, to all that is striving upwards in growth. Surely old people should look only patient and resigned--never triumphant--in this world? Some strong action with regard to Alice's position would be necessary. It was absurd to think that her father should eternally come between her and me. It would be necessary to go down to Cambridge and make a clean confession to Alice. And then, when forgiven, I would insist on an immediate arrangement concerning our marriage. Marriage! The word vibrated in my soul. The solemnity of that ceremony was great enough to mere mortals, but what would it mean to us when we were immortals? Sarakoff had hinted at a new marriage system. Was such a thing possible? On what factors did marriage rest? Was it merely a discipline or was it ultimately selfishness? My agitation increased, and I hurried eastwards, soon entering an area of riverside London that, had I been calmer, might have given me some alarm. It must have been about two o'clock in the morning when the pressure of thoughts relaxed in my mind. I found myself in the great dock area. The forms of giant cranes rose dimly in the air. A distant glare of light, where nightshifts were at work, illuminated the huge shapes of ocean steamers. The quays were littered with crates and bales. A clanking of buffers and the shrill whistles of locomotives came out of the darkness. For some time I stood transfixed. In my imagination I saw these big ships, laden with cargo, slipping down the Thames and out into the sea, carrying with them an added cargo to every part of the earth. For by them would the Blue Germ travel over the waterways of the world and enter every port. From the ports it would spread swiftly into the towns, and from the towns onwards across plain and prairie until the gift of Immortality had been received by every human being. The vision thrilled me....
