These conditions have come about in less than a century; most of them in a quarter of a century. Multiply them by the years of another century, and who shall say that the events I depict are impossible? There is an acceleration of movement in human affairs even as there is in the operations of gravity. The dead missile out of space at last blazes, and the very air takes fire. The masses grow more intelligent as they grow more wretched; and more capable of cooperation as they become more desperate. The labor organizations of to-day would have been impossible fifty years ago. And what is to arrest the flow of effect from cause? What is to prevent the coming of the night if the earth continues to revolve on its axis? The fool may cry out: "There shall be no night!" But the feet of the hours march unrelentingly toward the darkness. Some may think that, even if all this be true, "Cæsar's Column" should not have been published. Will it arrest the moving evil to ignore its presence? What would be thought of the surgeon who, seeing upon his patient's lip the first nodule of the cancer, tells him there is no danger, and laughs him into security while the roots of the monster eat their way toward the great arteries? If my message be true it should be spoken; and the world should hear it. The cancer should be cut out while there is yet time. Any other course "Will but skin and film the ulcerous place, While rank corruption, mining all beneath, infects unseen." Believing, as I do, that I read the future aright, it would be criminal in me to remain silent. I plead for higher and nobler thoughts in the souls of men; for wider love and ampler charity in their hearts; for a renewal of the bond of brotherhood between the classes; for a reign of justice on earth that shall obliterate the cruel hates and passions which now divide the world. If God notices anything so insignificant as this poor book, I pray that he may use it as an instrumentality of good for mankind; for he knows I love his human creatures, and would help them if I had the power. CHAPTER I THE GREAT CITY [This book is a series of letters, from Gabriel Weltstein, in New York, to his brother, Heinrich Weltstein, in the State of Uganda, Africa.] NEW YORK, Sept. 10, 1988 My Dear Brother: Here I am, at last, in the great city. My eyes are weary with gazing, and my mouth speechless with admiration; but in my brain rings perpetually the thought: Wonderful!--wonderful!--most wonderful! What an infinite thing is man, as revealed in the tremendous civilization he has built up! These swarming, laborious, all-capable ants seem great enough to attack heaven itself, if they could but find a resting-place for their ladders. Who can fix a limit to the intelligence or the achievements of our species?
