In 1728 he set up a printing house with the printer Hugh Meredith. But Meredith's father could not pay all the money he had promised. Then his friends William Coleman and Robert Grace each came to him separately and offered to lend him the money he needed to take over the printing house alone. He wrote in his autobiography that when Meredith withdrew from the partnership, he borrowed half from each of the two friends and took over the printing house on his own. The autobiography dates this to around 1729, but the record ending the partnership is dated 14 July 1730. Record
