Sin.; E, 2ft. The 

 knot used to fasten 

 the ropes to the 

 pegs is the clove- 

 hitch (shown in 

 Fig. 40), or the 

 anchor bend, which 

 is still stronger 



chain, 5.) We may also adopt the 

 mode of pegging used by military 

 engineers. The pegs A (Fig. 40), 

 are made of pine wood, they are 3 

 to 4| inches in diameter, ter- 

 minated by a square point, pro- 

 vided with an iron shoe 8, the 

 other end furnished with an iron 

 hoop F. At the foot of the peg 

 A (Fig. 41), the anchoring cable 

 Tis fastened level with, or slightly 

 below the surface of the soil ; this 

 peg is driven in a slanting direc- 

 tion to a depth of between lojto 

 19 J inches, its head b is joined 

 to the foot of the peg B, driven 

 6ft. 6 in. distant from it, and so 

 forth, for the pegs, C, D, E. The 

 length of the peg A is 5ft. 9in.; 

 B, 5ft. 3in.; C, 4ft. 6in.; D, 3ft.

 It is comprised of

(Fig. 42). The cable T is fastened 

 to the peg A, by two half-hitches 

 (Fig. 43). The two anchors N N 

 (Plate I.), are joined by a chain, 

 n ri, 32ft. lOin. in length, to one of 

 the links of which the chain g is 

 hooked. The chain n ri is some- 

 times replaced by a steel wire cable 

 of 0'6-inch in diameter. In this
