![An illustration from The sea-man's grammar and dictionary, explaining all the difficult terms in navigation: and The practical navigator and gunner: in two parts. : I. Most plain and easy directions, to build, rigg, yard, and mast any ship whatsoever. With the manner of working of a ship in all weathers: --and how to manage a fight at sea:--also the charge and duty of every officer in a ship, and their shares -- and the use of the petty-tally. II. An abstract of the art of gunnery, (or shooting in great ordnance and morter-pieces): wherein the principles of that art are plainly taught, both by arithmetical calculation, and by tables ready calculated -- with the compositions for the making of several fire-works useful in war, both at sea and land. --And an apendix [sic] how by several geometrical ways to take heights, depths, and distances, accessible or inaccessible.
