The instance mentioned in "Uncle Tom's Cabin," of a young mulatto, George Harris, inventing a machine, is _very solitary_. The negroes, like a good many of their owners, are opposed to innovations. They like the good old way. The hot sun under which they were born, and the hotter one that lighted the paths of their ancestors, prejudices them against any new effort. I think, _when they do get in Congress_, they will vote for agricultural against manufacturing interests. I am sure they would rather pick cotton than be confined to the din and dust of a factory. An old negro prefers to put his meal bags in a covered wagon, and drive them to market at his leisure, with his pocket full of the tobacco he helped to raise, and the whole country for a spit-box, to being whirled away bodily in a railroad car, in terror of his life, deaf with the whistling and the puffing of the engine. When Liberia or Africa does become a great nation, (Heaven grant it may soon,) they will require many other buildings there, before a patent office is called for. George Harris is a _natural_ Abolitionist, with a dark complexion. He is a remarkable youth in other respects, though I should first consider the enormous fact of George's master appropriating to himself the benefit of his servant's cleverness. Even with a show of right this may be a mean trick, but it is the way of the world. A large portion of New England men are at this time claiming each other's patents. I know of an instance down East, for Southerners can sometimes "tak notes, and prent 'em too." A gentleman took a friend to his room, and showed him an invention for which he was about to apply for a patent. The friend walked off with his hands in his pocket; his principles had met, and passed an appropriation bill; the invention had become his own--in plain English, he stole it. Washington is always full of people claiming each other's brains. The lawyers at the Patent Office have their hands full. They must keep wide awake, too. Each inventor, when he relates his grievances, brings a witness to maintain his claim. There is no doubt that, after a while, there will be those who can testify to the fact of having seen the idea as it passed through the inventor's mind. The way it is settled at present is this--whoever can pay the most for the best lawyer comes off triumphantly! Poor George is not the only smart fellow in the world outdone by somebody better off than himself.
