It must be remembered that at this time the slave-trade was not regarded as anything dishonorable. Numerous vessels were attracted to it as a money-making venture, and openly plied back and forth between the home of the black man and the island of Jamaica. Few sailors, few officers, few of the people at large, thought it wrong to steal lusty young negroes and negresses away from their parents and kinsmen and offer them for sale to the Jamaican slave-dealers and plantation owners. So young John Paul first engaged in the trade without any compunctions of conscience. But it was not for long. At the end of two years he had seen so many broken hearts among the blacks as a result of the forced partings, had been an observer of so much unnecessary suffering because of the cruelty of the rough fellows who handled the human freight, that his heart sickened. In fact, so disgusted was he that he even sold out the sixth interest which he had obtained in the ship, quitted it, and boarded the _John O'Gaunt_, at Kingston, Jamaica, bound as a passenger for Whitehaven. On the trip home the captain, mate, and all but five of the crew of the _John O'Gaunt_ died of yellow fever. Not a man was left, except John Paul, who knew enough about navigation to bring the afflicted ship into port. So the lad took charge. With neatness and dispatch he guided the brig across the dangerous waters of the Atlantic and into her haven. Her pleased owners rewarded him with a share of her cargo, and gratified him even more by making him captain and supercargo of a new ship--the _John_--which was engaged in the West Indian merchant trade. Life on a merchantman is rough enough to-day; it was far rougher at that time. To maintain discipline at sea required a strong hand and a tongue none too gentle. Kind-hearted enough by nature, John had learned his lessons by this time; he knew that indecision and softness had no place in an efficient skipper's makeup before his men, and while good enough to his crew at all times he insisted that they obey his commands with respect and promptness. During the third voyage of the _John_, when fever had greatly reduced the crew and every man on board was more or less fretful and irritable, Mungo Maxwell, a mulatto carpenter, became mutinous to such an extent that the young commander deemed it advisable to have him flogged, not only as fitting punishment, but as a salutary example for the observation of the remainder of the crew. The chastisement duly took place. It was not unusually severe, but it happened that, unknown to the youth, the man was just coming down himself with the scourge. He took to his bed, the fever gripped him, and he never arose again.
