Friend Hopper gave the sheriff a signal to serve the writ. He was a novice in the business, but in obedience to the instructions given him, he laid his hand on Mary's shoulder, and said, "By virtue of this writ, I replevin this woman, and deliver her to Mr. Hopper."
Her protector immediately said to her, "Thou canst now go home with me." But her mistress seized her by the arm, and said she should not go. The mayor was little acquainted with legal forms, beyond the usual routine of city business. He seemed much surprised, and inquired what the writ was.
"It is a homine replegiando," replied Friend Hopper.
"I don't understand what that means," said the mayor.
"It is none the less powerful on that account," rejoined Friend Hopper. "It has taken the woman out of thy power, and delivered her to another tribunal."
During this conversation, the mistress kept her grasp upon Mary. Friend Hopper appealed to the mayor, again repeating that the girl was now to await the decision of another court. He accordingly told Mrs. Sears it was necessary to let her go. She asked what was to be done in such a case. The mayor, completely puzzled, and somewhat vexed, replied impatiently, "I don't know. You must ask Mr. Hopper. His laws are above mine. I thought I knew something about the business; but it seems I don't."
Mary went home with her protector, and Mrs. Sears employed Alexander J. Dallas as counsel. The case was kept pending in the Supreme Court a long time; for no man understood better than Friend Hopper how to multiply difficulties. Mrs. Sears frequently attended, bringing witnesses with her from Maryland; which of course involved much trouble and expense. After several years, the trial came on; but it was found she had left some of her principal witnesses at home. Most of the forenoon was spent in disputes about points of law, and the admissibility of certain evidence. The court then adjourned to three in the afternoon.
Mrs. Sears was informed that even if the court adjudged Mary to be her slave, Friend Hopper would doubtless fail to produce her, and they would be compelled to go through another process to recover from him the penalty of the bond. She had become exceedingly weary of the law, the trouble and expense of which had far exceeded her expectations. She therefore instructed her lawyer to try to effect a compromise. Friend Hopper, being consulted for this purpose, offered to pay two hundred and fifty dollars for Mary if the claimant would pay the costs. She accepted the terms, well pleased to escape from further litigation.
When the court met in the afternoon, they were informed that the matter was settled; and the jury with consent of parties, rendered a verdict that Mary was free. By her own earnings, and donations from sympathizing friends, she gradually repaid Isaac W. Morris three hundred dollars toward the sum he had advanced for the expenses of her trial.
In his efforts to protect the rights and redress the wrongs of colored people, Friend Hopper had a zealous and faithful ally in Thomas Harrison, also a member of the Society of Friends. When recounting the adventures they had together, he used to say, "That name excites pleasant emotions whenever it occurs to me. I shall always reverence his memory. He was my precursor in Philadelphia, as the friend of the slave, and my coadjutor in scores of cases for their relief. His soul was always alive to the sufferings of his fellow creatures, and dipped into sympathy with the oppressed; not that idle sympathy that can be satisfied with lamenting their condition, and make no exertions for their relief; but sympathy, like the apostle's faith, manifesting itself in works, and extending its influence to all within its reach."
