Now who believes that it does not require more genius and skill to execute this minute work than it does to bore a Hoosac tunnel, or build a Victoria bridge, or put a dam across the Connecticut, or construct an Erie canal? I do not speak of the relative importance of the great works and the small, but of the relative amount and quality of the power that is brought to bear upon them. In a very important sense the greatest thing a man can do is the most difficult thing he can do. The most difficult thing a man can do may not be the most useful, or in any sense the most important; but it will measure and show the limits of his power. Work grows difficult as it goes below a man, quite as rapidly as it does when it rises above him. It costs as much skill to make a dainty bit of jewelry as it does to carve a colossal statue. It actually costs more power to make the chain of gold that holds the former, than it does to forge the clumsy links by which the latter is dragged to its location. Thus, whether man goes down or up, he soon gets beyond the sphere of his power. The further he can carry himself in either direction the more does he demonstrate his superiority over the majority of men. The more difficult the task which he performs the further does he reach toward infinity. In the town of Waltham there is a manufactory of watches which I have examined with great interest. It is here undertaken to organize the skill which has been achieved by thousands of patient hands, and submit it to machinery; and it is done. Every thing is so systematized, and the operations are carried on with such exactness, that, among a hundred watches, corresponding parts may be interchanged without embarrassment to the machinery. The different parts are passed from hand to hand, and from machine to machine, each hand and each machine simply doing its duty, and when from different and distant rooms these parts are assembled, and cunning fingers put them together, every wheel knows its place, and every pivot and every screw its home, though it be picked without discrimination from a dish containing ten thousand. Yet among these parts there are screws of which it takes one hundred and fifty thousand to make a pound, and shafts and bearings which are so delicately turned that five thousand shavings will only extend a lineal inch along the steel. This is the way American watches are made, and this is the way in which the highest practicable perfection is reached in the manufacture of these pocket monitors.
