Two half-hitches, either around a post or timber or around the standing part of the rope, make an ideal and quickly tied fastening (Figs. 34 and 35). To make these, pass the end around the post, ring, or other object, then over and around the standing part between the post and itself, then under and around the standing part and between its own loop and the first one formed. After a little practice you can tie this knot almost instantly and by merely throwing a couple of turns around a post, two half-hitches may be formed instantly. This knot will hold forever without loosening, and even on a smooth, round stick or spar it will stand an enormous strain without slipping.

A more secure knot for this same purpose is the "Clove Hitch" (Fig. 36), sometimes known as the "Builders' Hitch."

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.

These may be finished by a simple knot, or a bow-knot, as shown in Fig. 42, but they are likely to jam under great pressure and are mainly useful in tying packages, or bundles, with small cord, where the line must be held taut until the knot is completed.
