“The single fisherman’s bend, shown in Fig. 7, is excellent for uniting two ropes of similar size for temporary purposes, as it can readily be undone. Hence it has a tendency to work loose in course of time, and if it is necessary to unite two ropes of similar size for longer periods, it is better to use the figure of 8 tie, also known as the Flemish tie, shown in Fig. 4. This, though somewhat complicated, is strong and reliable and has no tendency to work loose.
“As regards making a loop in the middle of a rope, no entirely satisfactory knot has yet been devised. The ‘middleman noose,’ shown in the 1892 Alpine Club Report of the Special Committee on Equipment for Mountaineers (p. 4), has the fatal disadvantage that under certain conditions, when a pull is applied in a certain direction, it acts as a true noose—that is, as a slip or running knot. The best middle loop at present known is the open-handed loop, which is free from this disadvantage, and which is shown in Fig. 14.
“For an end loop, the bowline, shown in Fig. 11, is excellent. The loose end should be secured by a half-hitch (see 1892 Report, p. 4), or by an overhand knot; the latter, shown in Fig. 12, is preferable.
“Finally, a bowline on a bight, the most important ‘first aid’ knot for transporting an injured person, is shown in Fig. 16.”
Messrs. Kirkaldy made in my presence some interesting tests of knots, with the following results:
| Middleman Knot. | Strength relative to rope. |
| Manila rope | 44 per cent. |
| Flax rope | 50 per cent. |
| Single bowline Knot. | Strength relative to rope. |
| Manila rope | 55 per cent. |
| Flax rope | 59 per cent. |
This again shows that a knot reduces the efficiency of a flax rope less than that of the Manila rope.
New ropes should not be wetted or stretched before use, but the kinks should be carefully worked out by hand. And a wet rope must be dried in the shade.
The best length of rope for a party of three is 100 to 120 feet. It is a good plan on long, snow-covered glacier expeditions to carry a spare 50-foot rope, and on some difficult rock climbs a long spare rope is necessary. This can be of a lighter kind, about 1 inch circumference. Beale, 194 Shaftesbury Avenue, London, supplies a Manila alpine line very suitable for such a purpose.
