A Gunner ought to be a sober, wakeful, lusty, patient, prudent and quick Spirited Man ; he ought also to have a good eye-sight and a good judgment in the time of service, so to plant his Piece to do most hurt or execution, either to the Hull or rigging of a Ship, as may be most expedient according to the appointment of the Commander.

2. A Gunner ought to be skilful in Arithmetick and Geometry, in the making of all kind of Artificial Fire-Works, especially for service.

3. A Gunner ought to procure with all his power the Friendship and Love of every Person, and to take great care of his charge for his own safety as well as the Ship and all the Mens lives, by having special regard unto his Powder Room and to be well satisfied in the carefulness of those that he doth instruct to manage the business there, and to see that the Yeoman is careful always to keep a good and large Lanthorn, and to be kept whole, that it may prevent the flying in of the dust of the Powder, for the neglect of which it hath sometimes been conjectured that some Ships have been blown up and lost for want of care in the Powder Room.

4. A Gunner ought at the receipt of his charge, to make an Inventory of all such things as shall be committed to him, as well to render an account as to consider the want of such Materials as are necessary to the well performance of his duty.

5. A Gunner ought to have his Gun-Room always ready furnished with all necessaries belonging to his Art, which ought always to be in readiness, viz. Ladles, Rammers, Spunges, Gun-Powder, Balls, Tamkins, Wadds, Chain-shot, Cross-bar-shot, Quoins, Crows, Tackles, Breechings, Powder-Horns, Canvass, and Paper for Cartridges, Forms for Ladles, Cartridges, Needles and Threed to sow and bind the Cartridges, Candles, Lanthorns, Handspikes, Poleaxes, little Hand-Baskets, Glew and Past, with a sufficient Crew of able and expert Seamen, being yare-handed to travers a Piece, to Charge, Discharge, Mount, Wadd, Ram, make Clean, Spunge, and Prime and Scoure, and readily to do and perform any thing belonging to the Practical Part of Gunnery.

6. A Gunner ought always to have a Ruler about him, and a pair of Compasses, and Callabers to measure the heighth and length of every part of his concavity, and the length depth and wideness of every Ladle whereby he may know whether his Piece is laden with too much Powder, or is charged with a less quantity than it ought to have.

7. A Gunner ought to know the length and weight of all manner of Pieces, and be able to give an account readily how much Powder is a due charge for every Piece, and how many times a Piece may be shot off without harm, and how each kind of Piece should be charged with the Powder, Tamkin, Ball and Wadd.

8. A Gunner also must be skilful to make Salt-Petre, to refine and sublime Salt-Petre, to make divers sorts of Gun-Powder to purifie Brimstone, to amend any sort of Powder when it hath lost its vertue and force, and to know how much Salt-Petre ought to be put to the said unserviceable Powder, and to make it strong as it was before, and how many times the Salt-Petre that is put into the Powder ought to be refined.

9. A Gunner that serves at Sea must be careful to see that all their great Ordnance be fast breeched, and that all the furniture be handsome and in a readiness as was said before, and that they are circumspect about their Powder in the time of service, and to have an especial care of the Linstocks and Candles for fear of their Powder and their Fire-works, and the Oacum, which is very dangerous, and to keep your Pieces (as neer as you can within) : And also that you keep their Touch-holes clean without any kind of dross falling in them ; and it is good for the Gunner to view his Pieces and to know their perfect dispart, and to mark it upon the Piece or else in a Book or Table, and name every Piece what it is and where she doth lie in the Ship, and note how many inches halfs and quarters of inches the dispart cometh unto.
