15. Slip Knot. 



"The bowline 7 is one of the most useful knots; it will not slip, and after being strained is 

 easily untied. Commence by making a bight in the rope, then put the end through the bight 

 and under the standing part as shown in Fig. 2, then pass the end again through the bight, and 

 haul tight. 



"The square or reef knot 9 must not be mistaken for the 'granny' knot that slips under a 

 strain. Knots 8, 10 and 13 are easily untied after being under strain. The knot 13 is useful 

 when the rope passes through an eye and is held by the knot, as it will not slip, and is easily untied 

 after being strained.

"The timber-hitch, 19, looks as though it would give way, but it will not; the greater the 

 strain the tighter it will hold. The wall knot looks complicated; but is easily made by pro- 

 ceeding as follows: Form a bight with strand a and pass the strand b around the end of it, and 

 the strand c around the end of b, and then through the bight of a, as shown in the engraving 26. 

 Haul the ends taut, when the appearance is as shown in 27. The end of the strand a is now laid
