As I said before, slippery knots are bothersome in many cases. When you use the slip knot the only way to get it out is to cut the line; then you are disfiguring the line or shortening it.
The square knot and the bow-line knot are the ones most commonly used.
In tying a square knot take the ends of the rope, passing the left end over and under the right, and then take the right end and pass it over and under the left.

In using the square knot while working in the chair, make two half hitches in each end of the line. This is used to insure double safety.
When using the square knot for the purpose of adding more line to the riggings, tie both ends of the lines (as illustrated on page 61).
