_Light Pieces._—7 gives his spunge to 9; 7 and 8 unhook the chain
traces from the breast of the carriage, and lay them over the spokes
of the wheels; the driver brings up a horse to the front, by the
right; 7 and 8 unhook the horses traces from the back band, and hook
them to the short gun traces, and then take post outside the wheels; 7
takes his spunge.
_Heavy Pieces._—This is done with two horses, one before the other; 7
and 8 hook the horse, the driver rides to the rear horse, and 9 and 10
hook the rear horse to the short gun traces.
_Prepare for Action._—The different numbers exactly undo what they have
just done.
