prepared, near the other double block fix two more windlasses, to
which fasten a cord, and to it tie the other half of the ships as
before: when you fire the ships, pull in the cord with one of the
windlasses, to get all the ships together; and when you have set fire
to the first, turn that windlass which draws them out, and so on with
the rest, till they are all out in the middle of the pond; then, by
turning the other windlass, you will draw them back again; by which
method you may make them change sides, and tack about backwards and
forwards at pleasure. For the fire-ship fix the blocks and windlasses
between the others, so that when she sails out she will be between the
other ships: you must not let this ship advance till the guns at her
ports take fire.

_To fire Sky-Rockets under Water._

You must have stands made as usual, only the rails must be placed flat
instead of edgewise, and have holes in them for the rocket-sticks to
go through; for if they were hung upon hooks, the motion of the water
would throw them off: the stands being made, if the pond be deep
enough, sink them at the sides so deep, that, when the rockets are in,
their heads may just appear above the surface of the water; to the
mouth of each rocket fix a leader, which put through the hole with a
stick; then a little above the water must be a board, supported by the
stand, and placed along one side of the rockets; then the ends of the
leaders are turned up through holes made in this board, exactly
opposite the rockets. By this means you may fire them singly or all at
once. Rockets may be fired by this method in the middle of a pond, by
a Neptune, a swan, a water-wheel, or any thing else you choose.

_Neptune in his Chariot._

To represent Neptune in his chariot, 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 swimming. 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 pasteboard, 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
