So the hot day wore on in the town and country; the old sun glaring down like some fierce old judge, intolerant of weakness or shams,--baking the hard earth in the streets harder for the horses' feet, drying up the bits of grass that grew between the boulders of the gutter, scaling off the paint from the brazen faces of the interminable brick houses. He looked down in that city as in every American town, as in these where you and I live, on the same countless maze of human faces going day by day through the same monotonous routine. Knowles, passing through the restless crowds, read with keen eye among them strange meanings by this common light of the sun,--meanings such as you and I might read, if our eyes were clear as his,--or morbid, it may be. A commonplace crowd like this in the street without: women with cold, fastidious faces, heavy-brained, bilious men, dapper 'prentices, draymen, prize-fighters, negroes. Knowles looked about him as into a seething caldron, in which the people I tell you of were atoms, where the blood of uncounted races was fused, but not mingled,--where creeds, philosophies, centuries old, grappled hand to hand in their death-struggle,--where innumerable aims and beliefs and powers of intellect, smothered rights and triumphant wrongs, warred together, struggling for victory. Vulgar American life? He thought it a life more potent, more tragic in its history and prophecy, than any that has gone before. People called him a fanatic. It may be that he was one: yet the uncouth old man, sick in soul from some gnawing pain of his own life, looked into the depths of human loss with a mad desire to set it right. On the very faces of those who sneered at him he found some traces of failure or pain, something that his heart carried up to God with a loud and exceeding bitter cry. The voice of the world, he thought, went up to heaven a discord, unintelligible, hopeless,--the great blind world, astray since the first ages! Was there no hope, no help? The hot sun shone down, as it had done for six thousand years; it shone on open problems in the lives of these men and women who walked the streets, problems whose end and beginning no eye could read. There were places where it did not shine: down in the fetid cellars, in the slimy cells of the prison yonder: what riddles of human life lay there he dared not think of. God knows how the man groped for the light,--for any voice to make earth and heaven clear to him.
