On the 2d of December 1795, I took my departure from the hospitable mansion of Dr. Laidley. I was fortunately provided with a Negro servant, who spoke both the English and Mandingo tongues. His name was Johnson. He was a native of this part of Africa; and having in his youth been convoyed to Jamaica as a slave, he had been made free, and taken to England by his master, where he had resided many years; and at length found his way back to his native country. As he was known to Dr. Laidley, the Doctor recommended him to me, and I hired him as my interpreter, at the rate of ten bars monthly, to be paid to himself, and five bars a month to be paid to his wife during his absence.
