If it is impossible to measure the political effect of this work, we may at least assert that it gave a thrilling pleasure to ten millions of human beings,--an innocent pleasure, too, and one of many hours' duration. We may also say, that, while enjoying that long delight, each of those ten millions was made to see, with more or less clearness, the great truth that man is not fit to be trusted with arbitrary power over his fellow. The person who afforded this great pleasure, and who brought home this fundamental truth to so many minds, was Harriet Beecher Stowe, of Hartford, in the State of Connecticut, where she keeps house, educates her children, has a book at the grocery, and invites her friends to tea. To that American woman every person on earth who read "Uncle Tom's Cabin" incurred a personal obligation. Every individual who became possessed of a copy of the book, and every one who saw the story played in a theatre, was bound, in natural justice, to pay money to her for service rendered, unless she expressly and formally relinquished her right,--which she has never done. What can be clearer than this? Mrs. Stowe, in the exercise of her vocation, the vocation by which she lives, performs a professional service to ten millions of people. The service is great and lasting. The work done is satisfactory to the customer. What can annul the obligation resting upon each to render his portion of an equivalent, except the consent of the authoress "first had and obtained"? If Mrs. Stowe, instead of creating for our delight and instruction a glorious work of fiction, had contracted her fine powers to the point of inventing a nutcracker or a match-safe, a rolling-pin or a needle-threader, every individual purchaser could have been compelled to pay money for the use of her ingenuity, and everybody would have thought it the most natural and proper thing in the world so to do. There are fifty American inventions now in use in Europe from which the inventors derive revenue. _Revenue!_--not a sum of money which, once spent, is gone forever, but that most solid and respectable of material blessings, a sum per annum! Thus we reward those who light our matches. It is otherwise that we compensate those who kindle our souls.
