For four years following his maiden voyage, John Paul was a member of the crew of the _Friendship_. His voyages were mainly to and from the West Indies. During this time he managed to call twice upon his brother Willie in Virginia, and each time the people there grew to like him better, and he to appreciate the attractions of the New Country. He also had been to see his folks at Arbigland once or twice, on occasions when his ship was laying-over at Whitehaven, and these were happy occasions for all concerned, as we may suppose.
John's rise in the merchant service was rapid. When he was sixteen, a sturdy youth with the nimbleness of a cat and almost the strength of a man, Mr. Younger retired from business, and as a reward to the capability and faithfulness of his charge, the ship-owner returned him the indentures which made him his own master. In addition to this he presented him to the captain of the _King George_ of Whitehaven, a slaver, with recommendation that the lad be given an appointment as first-mate.
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.
