Apparently the mate did. He whipped out a knife, but found it suddenly knocked out of his hand, and sent skimming like a silver flying fish far over the gleaming river. He followed up the attack with an assault from both hands and feet, but soon discovered that he had to deal with an artist. He gathered himself up at the end of half a minute's interview, glared from two half-shut eyes, wiped the blood from his mouth, and inquired what Kettle wanted. "You heard my order. Carry it out." The man nodded, and went away sullenly muttering that his time would come. "If you borrow another knife," said Kettle cheerfully, "and try any more of your games, I'll shoot you like a crow, and thank you for the chance. You'll go forrard and clean the forecastle-head and the fore main deck. Be gentle with those sick! Second Mate?" "Si, Señor." "Get a crew together and clean her up aft here. Do you want any rousing along?" Apparently the second mate did not. He had seen enough of Captain Kettle's method already to quite appreciate its efficacy. The Krooboys, with the custom of servitude strong on them, soon fell-to when once they were started. The thump of holy-stones went up into the baking air, and grimy water began to dribble from the scuppers. With the chief engineer Kettle had another scuffle. But he, too, was eased of the knife at the back of his belt, thumped into submissiveness, and sent with firemen and trimmers to wash paint in the stewy engine-room below, and clean up the rusted iron work. And then those of the passenger boys who were not sick, were turned-to also. With Captain Rabeira, Kettle did not interfere. The man stayed in his own room for the present, undisturbed and undisturbing. But the rest of the ship's complement were kept steadily to their employment. They did not like it, but they thought it best to submit. Away back from time unnumbered, the African peoples have known only fear as the governing power, and, from long acclimatization, the Portuguese might almost count as African. This man of a superior race came and set himself up in authority over them, in defiance of all precedent, law, everything; and they submitted with dull indifference. The sweets of freedom are not always appreciated by those who have known the easy luxury of being slaves. The plague was visibly stayed from almost the very first day that Kettle took over charge. The sick recovered or died; the sound sickened no more; it seemed as though the disease microbes on board the ship were glutted. A mile away, at the other side of the beer-colored river, the rare houses of Boma sprawled amongst the low burnt-up hills, and every day the doctor with his bad liver came across in his boat under the blinding sunshine to within shouting distance, and put a few weary questions. The formalities were slack enough. Nilssen usually made the necessary replies (as he liked to keep himself in the doctor's good books), and then the boat would row away.
