be quite satisfied to witness the next operation performed upon a pasteboard sphere that began to exist some weeks earlier, and is now hard to the core. The wooden ball, with its solid paper covering, is placed on its axis. A sharp cutting instrument, fixed on a bench, is brought into contact with the surface of the sphere, which is made to revolve. In less time than we write, the pasteboard ball is cut in half. There is no adhesion to the wooden mould, for the first coating of paper was simply _wetted_. Two bowls of thick card now lie before us, with a small hole in each, made by the axis of the wooden ball. But a junction is very soon effected. Within every globe there is a piece of wood—we may liken it to a round ruler—of the exact length of the inner surface of the sphere from pole to pole. A thick wire runs through this wood, and originally projected some two or three inches at each end. This stick is placed upright in a vice. The semi-globe is nailed to one end of the stick, upon which it rests, when the wire is passed through its centre. It is now reversed, and the edges of the card rapidly covered with glue. The edges of the other semi-globe are instantly brought into contact, the other end of the wire passing through its centre in the same way, and a similar nailing to the stick taking place. We have now a paper globe, with its own axis, which will be its companion for the whole term of its existence. The paper globe is next placed on its axis in a frame, of which one side is a semi-circular piece of metal;—the horizon of a globe cut in half would show its form. A tub of white composition,—a compound of whiting, glue, and oil is on the bench. The workman dips his hand into this ‘gruel thick and slab,’ and rapidly applies it to the paper sphere with tolerable evenness: but as it revolves, the semi-circle of metal clears off the superfluous portions. The ball of paper is now a ball of plaster externally. Time again enters largely into the manufacture. The first coating must thoroughly dry before the next is applied; and so again till the process has been repeated four or five times. Thus, when we visit a globe workshop, we are at first surprised at the number of white balls, from three inches diameter to three feet, which occupy a large space. They are all steadily advancing towards completion. They cannot be hurriedly dried. The duration of their quiescent state must depend upon the degrees of the thermometer in the ordinary atmosphere. They cost little. They consume nothing beyond a small amount of rent. As they advance to the dignity of perfect spheres, increased pains are taken in the application of the plaster. At last they are polished. Their surface is as hard and as fine as ivory. But, beautiful as they are, they may, like many other beautiful things, want a due equipoise. They must be perfectly balanced. They must move upon their poles with the utmost exactness. A few shot, let in here and there, correct all irregularities.
