The Abolitionists and Socialists, who, alone, have explored the recesses of social science, well understand that they can never establish their Utopia until private property is abolished or equalized. The man without property is theoretically, and, too often, practically, without a single right. Air and water, 'tis generally believed, are the common property of mankind; but nothing is falser in fact as well as theory. The ownership of land gives to the proprietor the exclusive right to every thing above and beneath the soil. The lands are all appropriated, and with them the air above them, the waters on them, and the mines beneath them. The pauper, to breathe the air or drink the waters, must first find a place where he may rightfully enjoy them. He can find, at all times, no such place, and is compelled, by his necessities, to inhale the close and putrid air of small rooms, damp cellars and crowded factories, and to drink insufficient quantities of impure water, furnished to him at a price he can ill afford. He pays for the water which he drinks, because it has ceased to be common property. He is not free, because he has no where that he may rightfully lay his head. Private property has monopolized the earth, and destroyed both his liberty and equality. He has no security for his life, for he cannot live without employment and adequate wages, and none are bound to employ him. If the earth were in common, he could always enjoy not only air and water, but by his industry might earn the means of subsistence. His situation is theoretically and practically desperate and intolerable. Were he a slave, he would enjoy in fact as well as in legal fiction, all necessary and essential rights. Pure air and water, a house, sufficient food, fire, and clothing, would be his at all times. Slavery is a form of communism, and as the Abolitionists and Socialists have resolved to adopt a new social system, we recommend it to their consideration. The manner in which the change shall be made from the present form of society to that system of communism which we propose is very simple. Negro slaves are now worth seven hundred dollars a-head. As whites work harder, they are worth about a thousand. Make the man who owns a thousand dollars of capital the guardian (the term master is objectionable) of one white pauper of average value; give the man who is worth ten thousand dollars ten paupers, and the millionaire a thousand. This would be an act of simple mercy and justice; for the capitalists now live entirely by the proceeds of poor men's labor, which capital enables them to command; and they command and enjoy it in almost the exact proportions which we have designated. Thus, a family of poor laborers, men, women and children, ten in number, can support themselves, and make about six hundred dollars, for their employer, which is the interest on ten thousand. They would work no harder than they do now, would be under no greater necessity to work, would be
