To make a fire-tree, as shewn by fig. 44. you must first have a piece of wood six feet in length, and three inches square, then at E, nine inches from the top, make a hole in the front, and in each side, or instead of holes you may fix short pegs, to fit the inside of the cases. At F, nine inches from E, fix three more pegs; at G, one foot nine inches from F, fix three pegs; at H, nine inches from G, at I, nine inches from H, fix three pegs, inclining downwards, but all the other pegs, must incline upwards, in order that the cases may have the same inclination as you see in the figure; then at top place a four inch mortar, loaded with stars, rains, or crackers. In the middle of this mortar, place a case filled with any sort of charge, but let it be fired with the other cases: a brilliant charge will do for all the cases, but the mortar may be made of any diameter, and the tree of any size, and on it any number of cases, provided they are placed in the manner described. Of Chinese Fountains. To make a Chinese fountain, you must have a perpendicular piece of wood, seven feet in length, and two inches and a half square. Sixteen inches from the top; fix on the front, a cross piece, one inch thick, and two and a half broad, with the broad side upwards; below this, fix three more pieces, of the same width and thickness, at sixteen inches distance from each other; let the bottom rail be five feet in length, and the others of such a length, as to allow the fire pumps to stand in the middle of the intervals of each other. The pyramid being thus made, fix in the holes made in the bottom rail, five fire pumps, at equal distances; on the second rail place four pumps; on the third, three; on the fourth, two; and on the top of the post, one; but place them all to incline a little forwards, that when they throw out the stars, they may not strike against the cross rails; having fixed your fire pumps, cloath them with leaders, so that they may all be fired together, see fig. 45.
