The offer was gladly accepted; and in 1805 he removed to Philadelphia, with his mother and family. He sawed wood for a living, and soon established such a character for industry and honesty, that many of the citizens were in the habit of employing him to purchase their wood and prepare it for the winter. Upon one occasion, when he brought in a bill to Alderman Todd, that gentleman asked if he had not charged rather high. Daniel excused himself by saying he had an aged mother to support, in addition to his own family; and that he punctually paid his master twenty dollars every six months, according to an agreement he had made with him. When the alderman heard the particulars, his sympathy was excited, and he wrote a note to Isaac T. Hopper, requesting him to examine into the case; stating his own opinion that Daniel had a legal right to freedom. The wood-sawyer started off with the note with great alacrity, and delivered it to Friend Hopper, saying in very animated tones, "Squire Todd thinks I am free!" He was in a state of great agitation between hope and fear. When he had told his story, he was sent home to get receipts for all the money he had paid his master since his arrival in Philadelphia. It was easy to prove from these that he had been a resident in Pennsylvania, with his owner's consent, a much longer time than the law required to make him a free man. When Friend Hopper gave him this information, he was overjoyed. He could hardly believe it. The tidings seemed too good to be true. When assured that he was certainly free, beyond all dispute, and that he need not pay any more of his hard earnings to a master, the tears came to his eyes, and he started off to bring his wife, that she also might hear the glad news. When Friend Hopper was an old man, he often used to remark how well he remembered their beaming countenances on that occasion, and their warm expressions of gratitude to God. Soon after this interview, a letter was addressed to Perry Boots, informing him that his slave was legally free, and that he need not expect to receive any more of his wages. He came to Philadelphia immediately, to answer the letter in person. His first salutation was, "Where can I find that ungrateful villain Dan? I will take him home in irons." Friend Hopper replied, "Thou wilt find thyself relieved from such an unpleasant task; for I can easily convince thee that the law sustains thy slave in taking his freedom." Reading the law did not satisfy him. He said he would consult a lawyer, and call again. When he returned, he found Daniel waiting to see him; and he immediately began to upbraid him for being so ungrateful. Daniel replied, "Master Perry, it was not _justice_ that made me your slave. It was the _law_; and you took advantage of it. Now, the law makes me free; and ought you to blame me for taking the advantage which it offers me? But suppose I were not free, what would you be willing to take to manumit me?"
