For a general rule: Let none presume to shoot off a piece of ordnance but in discovery of a ship or fleet by night, or by being in danger of an enemy, or in danger of fire, or in danger of sinking, that it may be unto us all a most certain intelligence of some matter of importance.
*14.

And you shall make us know the difference by this: if you give chase and being near a ship you shall shoot to make her strike, we shall all see and know that you shoot to that end if it be by day; if by night, we shall then know that you have seen a ship or fleet none of our company; and if you suspect we do not hear the first piece then you may shoot a second, but not otherwise, and you must take almost a quarter of an hour between your two pieces.
*15.

If you be in danger of a leak--I mean in present danger--you shall shoot off two pieces presently one after another, and if in danger of fire, three pieces presently one after another; but if there be time between we will know by your second piece that you doubt that we do not hear your first piece, and therefore you shoot a second, to wit by night, and give time between.
16.

There is no man that shall strike any officer be he captain, lieutenant, ensign, sergeant, corporal of the field,[6] quartermaster, &c.
17.

Nor the master of any ship, master's mate, or boatswain, or quartermaster.
