He worked with his new employer awhile, and then formed an arrangement with two journeymen clock-makers. Having perfected their plans, the three set out for New Jersey in a lumber wagon, carrying their provisions with them. The two clock-makers were to make and set up the works, and Jerome was to make the cases whenever they should succeed in selling a clock on their journey. Clock-making was then considered almost perfect. It had been reduced to a regular system, and the cost of construction had been very greatly lessened. A good clock, with a case seven feet high, could now be made for forty dollars, at which price it yielded a fair profit to the maker. The three young men were tolerably successful in their venture. Jerome worked fifteen hours a day at case-making, and by living economically, managed to carry some money with him when he went back to his master's shop in the spring. For the remaining three years of his apprenticeship he employed his winters in learning the various branches of clock-making, and not only earned enough money to clothe himself, but laid by a modest sum besides. In 1814, being twenty-one years of age and his own master, he set up a carpenter shop of his own, being not yet sufficiently master of clock-making to undertake that on his own account. In 1815, he married. Times were hard. The war with England had just ended, and labor was poorly compensated. He is said at this time to have "finished the whole interior of a three-story house, including twenty-seven doors and an oak floor, nothing being found for him but the timber," for the beggarly sum of eighty-seven dollars--a task which no builder would undertake to-day for less than a thousand dollars. Still, he declared that, in spite of this poor rate of compensation, he was enabled to save enough to make a partial payment on a small dwelling for himself. It required a constant struggle, however, to live at this rate, and in the winter of 1816, being out of work, and having a payment on his house to meet in the spring, he determined to go to Baltimore to seek work during the winter. He was on the eve of starting, when he learned that Mr. Eli Terry, the inventor of the wooden clocks which were so popular fifty years ago, was about to open a large factory for them in an adjoining town. He walked to the town, and made his application to Mr. Terry, who at once engaged him at liberal wages. Mr. Terry's factory was then the largest in the country, and, as he used wooden instead of metal works, he was able to manufacture his best clocks at fifteen dollars, and other grades in proportion. This reduction in price largely increased the sale of his clocks, and in a comparatively short time after opening his factory, Mr. Terry made and sold about six thousand clocks a year.
