The last column on the right in the above table, expresses the distance from the top of the cone, where the stick, when tied on, should ballance the rocket, so as to stand in an equilibrium on one’s finger or the edge of a knife. The best wood for the sticks is dry deal, made after the following manner; when you have cut and planed the sticks according to the dimensions given in the table, cut on one of the flat sides at top, a groove the length of the rocket, and as broad as the stick will allow; then on the opposite flat side, cut two notches for the cord, which ties on the rocket, to lay in; one of these notches must be near the top of the stick, and the other facing the neck of the rockets; the distance between these notches may easily be known, for the top of the stick should always touch the head of the rocket. When your rockets and sticks are ready, lay the rockets in the grooves in the sticks and tie them on. Those who, merely for curiosity, may chose to make rockets of different sizes, to what I have expressed in the table of dimensions, may find the length of their sticks, by making them for rockets, from half an ounce to one pounds sixty diameters of the rocket long; and for rockets above one pound, fifty or fifty-two diameters will be a good length; their thickness at top may be about half a diameter, and their breadth a very little more; their square at bottom is generally equal to half the thickness at top. But, although the dimensions of the sticks be very nicely observed, you must depend only on their ballance: for, without a proper counterpoise, your rockets, instead of mounting perpendicularly, will take an oblique direction, and fall to the ground before they are burnt out. The Method of Boring Rockets which have been drove solid.
