There is also a third method, by which these kind of rockets are managed, which is thus: In the top of the rocket fix a piece of wood, in which drive a small iron spindle, then make a hole in the middle of the small case, through which put the spindle; then fix on the top of it a nut, to keep the case from falling off; when this is done, the case will turn very fast, without the rocket: but this method does not answer so well, as either of the former. Fsg. 34. is a honorary rocket compleat. The best sized rockets for this purpose are those of one pound. To divide the Tail of a Sky Rocket, so as to form an Arch when ascending. Having some rockets made, and headed according to fancy, and tied on their sticks; get some sheet tin, and cut it into round pieces, about three or four inches diameter, then on the stick of each rocket, under the mouth of the case, fix one of these pieces of tin; sixteen inches from the rockets neck, and support it by a wooden bracket, as strong as possible: the use of this, is, that when the rocket is ascending, the fire will play with great force on the tin, which will divide the tail in such a manner, that it will form an arch, as it mounts, (and will have a very good effect if well managed) if there be a short piece of port-fire, of a strong charge, tied to the end of the stick, it will make a great addition; but this must be lighted, before you fire the rocket. To make several Sky Rockets, rise together, in the same direction, and equally distant from each other. Take six or any number of sky rockets, of what size you please; then cut some strong pack-thread, into pieces of three or four yards long, and tie each end of these pieces to a rocket in this manner. Having tied one end of your pack-thread, round the body, of one rocket, and the other end to another; take a second piece of pack-thread and make one end of it fast to one of the rockets already tied, and the other end to a third rocket, so that all the rockets except the two outside ones will be fastened to two pieces of pack-thread; the length of thread, from one rocket to the other, may be what the maker pleases; but the rockets must be all of a size, and their heads filled with the same weight of stars, rains, &c. Having thus done, fix in the mouth of each rocket, a leader of the same length; and, when you are going to fire them, hang them almost close together, then tie the ends of the leaders together, and prime them; this prime being fired, all the rockets will mount at the same time, and divide themselves as far as the firings will allow; which division they will keep, provided they are all rammed alike, and well made. These sort of rockets, are called by some, chained-rockets. Of Signal Sky Rockets.
