In order to represent this, to perfection, you must have a Neptune made (of wood, or basket work), as big as life, fixed on a float, large enough to bear his weight; on which must be two horses heads, and necks, so as to seem swiming, as they are shown by Fig. 35. For the wheels of the chariot, there must be two vertical wheels, of black fire, and on Neptune’s head a horizontal wheel, of brilliant fire, with all its cases to play upwards. When this wheel is made, cover it with paper, or, paste board, cut and painted like Neptune’s coronet; then let the trident be made without prongs, but instead of them, fix three cases of a weak grey charge, and on each horse’s head, put an eight ounce case of brilliant fire, and on the mouth of each, fix a short case of the same diameter, filled with the white flame receipt, enough to last out all the cases on the wheels; these short cases must be open at bottom, that they may light the brilliant fires; for the horses eyes, put small port fires, and in each nostril, put a small case filled half with grey charge, and the rest with port fire composition. If Neptune is to give fire, to any building on the water; at his first setting out, the wheels of the chariot, and that on his head, together with the white flames on the horses head, and the port fires in their eyes and nostrils, must all be lighted at once; then from the bottom of the white flames, carry a leader, to the trident. As Neptune is to advance by the help of a block and cord, you must manage it so as not to let him turn about, till the brilliant fires on the horses, and the trident, begins, for it is by the fire from the horses, (which plays almost upright) that the building, or work, is lighted; which must be thus prepared. From the mouth of the case, which is to be first fired, hang some loose quick match, to receive the fire from the horses. When Neptune, is only to be shewn by himself, without setting fire to any other works; let the white flames on the horses, be very short, and not to last longer than one case of each wheel, and let two cases of each wheel burn at a time.
