It speaks volumes in favor of the intelligence of John Paul, that he became so thoroughly disgusted with the cruelty of the traffic, desolating Africa with the most merciless wars, and tearing husbands from wives, parents from children, that, upon his return to Kingston, he declared that he would have nothing more to do with the traffic forever. His friends unite in giving their testimony to this his resolve, and it is confirmed by the uniform tenor of his subsequent correspondence. From this his second slaving voyage he embarked for Scotland, as a passenger, on board the brigantine John, under the command of Captain Macadam. On the passage the yellow fever broke out. Both the captain and the mate of the ship died. They were left in the middle of the stormy Atlantic, with none of the crew capable of navigating the ship. Fortunately for all, John Paul assumed the command. The whole crew gratefully recognized his authority. Be it remembered that he had not yet finished his twentieth year. He brought the ship safe into port. The owners, Messrs. Currie, Beck & Co., in recompense of the great service he had rendered them, at once gave him command of a ship both as captain and supercargo. In their employment he sailed for two voyages. On one of these voyages, Captain Paul was accused of whipping, with undue severity, an insubordinate sailor, by the name of Mungo Maxwell. But a legal investigation absolved him from all blame. The accusation, and the trial which was prolonged through six months, caused Captain Paul great annoyance. The following letter to his mother and sisters reveals his feelings, and much of his character, at that time. He was then but twenty-five years of age. “LONDON, 24th September, 1772. “MY DEAR MOTHER AND SISTERS, “I only arrived here last night from the Grenadas. I have had but poor health during the voyage. My success in it not having equalled my first sanguine expectations, has added very much to the asperity of my misfortunes, and, I am well assured, was the cause of my loss of health. I am now, however, better, and I trust Providence will soon put me in a way to get bread, and, which is far my greatest happiness, to be serviceable to my poor but much valued friends. I am able to give you no account of my future proceedings, as they depend upon circumstances which are not fully determined. “I have enclosed to you a copy of an affidavit made before Governor Young, by the Judge of the Court of Vice-Admiralty of Tobago, by which you will see with how little reason my life has been thirsted after, and, which is much dearer to me, my honor, by maliciously loading my fair character with obloquy and vile aspersions. I believe there are few who are hard-hearted enough to think I have not long since given to the world every satisfaction in my power, being conscious of my innocence before Heaven, who will one day judge even my judges.
