First roll some paper pipes, about fourteen inches in length each; these pipes must not be made thick of paper, two or three rounds of elephant paper being sufficient; when your pipes are thoroughly dryed, you must have made a tin tube, twelve inches in length, to fit easy into the pipes; at one end of this tube fix a small conical cup, which being done, it is called a funnel, then bend one end of one of the pipes, and put the funnel in at the other, as far as it will reach, and fill the cup with composition; then draw out the funnel by a little at a time, shaking it up and down, and it will fill the pipe as it comes out; having filled some pipes, have made some small blocks, about an inch diameter, and half an inch in thickness; round one of these blocks wind and paste a pipe, and to the end of this pipe join another, which must be done by twisting the end of one pipe to a point, and putting it into the end of the other, with a little paste; in this manner join four or five pipes, winding them one upon the other, so as to form a spiral line; having wound on your pipes, paste two slips of paper across them, to hold them together; besides these slips of paper, the pipes must be pasted together. [Illustration: PLATE 5.] [Illustration: PLATE 6.] [Illustration: PLATE. 7] [Illustration: PLATE. 8] There is another method of making these wheels, called the French method; which is, by winding on the pipes without paste, and sticking them together with sealing wax, at every half turn; so that when they are fired, the end will fall loose every time the fire passes the wax, by which means the circle of fire will be considerably increased. The formers for these pipes are made from one and a half to four sixteenths of an inch diameter, and the composition for them as follows; meal powder eight ounces, salt petre two ounces, and sulphur one; among these ingredients, may be mixed a little steel-filings, or the dust of cast-iron; this composition should be very dry, and not made too fine, or it will stick in the funnel. These wheels may be fired on a large pin, and held in the hand with safety. Of Fire Globes. There are two sorts of fire globes, one with projected cases, and the other with the cases concealed in the following manner; have a globe made of wood, of any diameter you chuse, and divide the surface of it into fourteen equal parts, and at each division bore a hole perpendicular to the center; these holes must be in proportion to the cases intended to be used; in every hole, except one, put a case filled with brilliant, or any other charge, and let the mouths of the cases be even with the surface of the globe; then cut in the globe a groove, from the mouth of one case to the other, for leaders, which must be carried from case to case, so that they may all be fired together; this being done, cover the globe with a single paper, and paint it. These sort of globes may be used to ornament a building.
