To make this, pass the end of rope around the spar or timber, then over itself; over and around the spar, and pass the end under itself and between rope and spar, as shown in the illustration.
The Clove hitch with ends knotted becomes the "Gunners' Knot" (Fig. 37). These are among the most valuable and important of knots and are useful in a thousand and one places. The Clove hitch will hold fast on a smooth timber and is used extensively by builders for fastening the stageing to the upright posts. It is also useful in making a tow-line fast to a wet spar, or timber, and even on a slimy and slippery spile it will seldom slip.
For this purpose the "Timber Hitch" (Fig. 38) is even better than the Clove hitch. It is easily made by passing the end of a rope around the spar or log, round the standing part of the rope and then twist it three or more times around, under and over itself.
If you wish this still more secure, a single half-hitch may be taken with the line a couple of feet further along the spar (Fig. 39).
It is remarkable what power to grip a twisted rope has, and the "Twist Knots" shown in Figs. 40 and 41 illustrate two ways of making fast which are really not knots at all but merely twists.
