And meanwhile Captain Owen Kettle, stripped to shoes and trousers, sweated over his work in the baking heat. Twice had a bullet grazed him, once on the neck, and once on the round of a shoulder, and red stains grew over the white satin of his skin. The work was strange to him certainly, but he set about it with more than an amateur's skill. All sailors have been handy with their fingers from time immemorial, but the modern steamer-sailor, during his apprenticeship as mate, has to turn his hand to a vast variety of trades. He is painter, carpenter, stevedore, crew-driver, all in one day; and on the next he is doctor, navigator, clerk, tailor, and engineer. And especially he is engineer. He must be able to drive winch, windlass, or crane, like an artist; he must have a good aptitude for using hand tools; and if he can work machine tools also, it is so much the better for him.
Yes, Captain Kettle put the patch on that boiler like a workman. He fitted his bolts, and made his joints; then luted the manhole and bolted that back in place; and then stepped down while a couple of negroes sluiced him with water from gourds, and rubbed him clean and dry with handfuls of wild cotton waste. So far, although the incessant hail of bullets had pitted the boiler's skin in a hundred places, no second shot had found a spot sufficiently soft to make a puncture. The range of the bombardment was long, perhaps, and though a bullet at seven hundred yards may, with convenience, kill a man, it will not pierce seven-eighths boiler plate. And so, theoretically, the boiler was safe for the time being.
But practically it was otherwise. The boiler was by no means new. It was corroded with years, and incapacity, and neglect, as is the custom with all parts of boats and machinery on the Haut Congo. But it had been brought up to that waterway by carriers at vast expense from Matadi, the highest steamer port on the Lower Congo, probably costing three months and a dozen lives in transit, so that it was debited in the books of the Free State as being worth its weight in silver, and destined to be used on without replacement till it saw fit to burst.
So Kettle knew that in places it would be not much thicker than stout brown paper, and was quite aware that if any of the pattering bullets investigated one of these patches, he would have to do his work over again. He had a strong--and, I think, natural--disinclination for this. He had come through terrific risks during the last four hours, and could not expect to do so a second time with equal immunity; his two wounds smarted; and (although it sounds ludicrous that such a thing should have weight) the dirt inseparable from such employment jarred against his neat and cleanly habits, and filled him with unutterable disgust.
