Dr. Hopkins was a poor man, but one of his first acts, after becoming convinced of the wrongfulness of slavery, was to appropriate the very sum which, in the days of his ignorance, he had obtained as the price of his slave to the benevolent purpose of educating some pious colored men in the town of Newport, who were desirous of returning to their native country as missionaries. In one instance he borrowed, on his own responsibility, the sum requisite to secure the freedom of a slave in whom be became interested. One of his theological pupils was Newport Gardner, who, twenty years after the death of his kind patron, left Boston as a missionary to Africa. He was a native African, and was held by Captain Gardner, of Newport, who allowed him to labor for his own benefit, whenever by extra diligence he could gain a little time for that purpose. The poor fellow was in the habit of laying up his small earnings on these occasions, in the faint hope of one day obtaining thereby the freedom of himself and his family. But time passed on, and the hoard of purchase-money still looked sadly small. He concluded to try the efficacy of praying. Having gained a day for himself, by severe labor, and communicating his plan only to Dr. Hopkins and two or three other Christian friends, he shut himself up in his humble dwelling, and spent the time in prayer for freedom. Towards the close of the day, his master sent for him. He was told that this was his gained time, and that he was engaged for himself. "No matter," returned the master, "I must see him." Poor Newport reluctantly abandoned his supplications, and came at his master's bidding, when, to his astonishment, instead of a reprimand, he received a paper, signed by his master, declaring him and his family from thenceforth free. He justly attributed this signal blessing to the all-wise Disposer, who turns the hearts of men as the rivers of water are turned; but it cannot be doubted that the labors and arguments of Dr. Hopkins with his master were the human instrumentality in effecting it. In the year 1773, in connection with Dr. Ezra Stiles, he issued an appeal to the Christian community in behalf of a society which he had been instrumental in forming, for the purpose of educating missionaries for Africa. In the desolate and benighted condition of that unhappy continent he had become painfully interested, by conversing with the slaves brought into Newport. Another appeal was made on the subject in 1776.
