August had blazed its path into September, and September had already trimmed her successor's gown with gold and russet before Henry Rogers found himself free again to think of holidays. London had kept its grip upon him all these weeks while the rest of the world was gay and irresponsible. He was so absurdly conscientious. One of his Companies had got into difficulties, and he was the only man who could save the shareholders' money. The Patent Coal Dust Fuel Company, Ltd., had bought his invention for blowing fine coal dust into a furnace whereby an intense heat was obtainable in a few minutes. The saving in material, time, and labour was revolutionary. Rogers had received a large sum in cash, though merely a nominal number of the common shares. It meant little to him if the Company collapsed, and an ordinary Director would have been content with sending counsel through the post in the intervals of fishing and shooting. But Henry Rogers was of a different calibre. The invention was his child, born by hard labour out of loving thought. The several thousand shareholders believed in him: they were his neighbours. Incompetence and extravagance threatened failure. He took a room in the village near the Essex factories, and gave his personal energy and attention to restoring economical working of every detail. He wore overalls. He put intelligence into hired men and foremen; he spent his summer holiday turning a system of waste into the basis of a lucrative industry. The shareholders would never know whose faithfulness had saved them loss, and at the most his thanks would be a formal paragraph in the Report at the end of the year. Yet he was satisfied, and worked as though his own income depended on success. For he knew--of late this certainty had established itself in him, influencing all he did--that faithful labour, backed by steady thinking, must reach ten thousand wavering characters, merge with awakening tendencies in them, and slip thence into definite daily action. Action was thought materialised. He helped the world. A copybook maxim thus became a weapon of tempered steel. His Scheme was bigger than any hospital for disabled bodies. It would still be cumulative when bodies and bricks were dust upon the wind. It must increase by geometrical progression through all time.
