KNOTS AND BRAIDS

Most of us are called upon, in the course of our daily duties, whether

afloat or ashore, in camp or at home, to hitch up pack animals, do

up packages, equipments and outfits, and make fastenings on sails,

tents, scaffolding and play apparatus. This involves the tying of a

great number of knots and in many cases life and limb depend upon the

correct tying of those knots. The seamen, textile workers and civil

engineers are pastmasters of the art. Our scouts, sailors and soldiers

are taught knot-tying as an essential factor in their training. Would

it not seem a part of wisdom, for the sake of safety and economy in

time and good nature, for everybody to master these knot problems? It

would, at least, be a very practical part of the training for children

in the schools.

They should be taught knot-tying and its application in an intelligent

and thoro manner, and have frequent practice-drill therein, till it

becomes second nature to them.

When a knot is tied, it must be pulled together tight, so as to stay.

Otherwise, especially if the cord is stiff, the loops will slide apart

or flop out of position, and the knot will come loose. A knot derives

its strength and reliability from the friction between its different

parts. When tension is applied on a knot, the two parts which lie

alongside of each other should move in the reverse directions and

produce a maximum amount of friction, as the ropes tend to slip.

One may readily learn to tie the different knots by carefully

following the accompanying drawings. Procure a slender, flexible

rope, bend it into the shape shown in the drawing, and go over and

under, as indicated, so that the parts will be in the correct relative

positions. Begin by making the simple knots, and, later, tackle the

more complex ones. Also learn their names.
