A fascine is a cylindrical bundle of brushwood tightly bound. The usual length is 18 feet, the diameter 9 inches, and the weight normally about 140 pounds. Lengths of 6 and 9 feet, which are sometimes used, are most conveniently obtained by sawing a standard fascine into two or three pieces.
Plate 29a.—Fascine.
Fascines are made in a cradle which consists of five trestles, the outer ones being 16 feet apart. The trestle is made by driving two sticks about 6½ feet long and 3 inches in diameter in the ground and lashed at the intersection as shown in Plate 29a. In making the cradle, plant the two end trestles first. Stretch a line from one to the other over the intersection. Place the others 4 feet apart and lash them so that each intersection comes fairly to the line.
To build a fascine, straight pieces of brush, 1 or 2 inches at the butt, are laid on, the butts projecting at the end 1 foot beyond the trestle. Leaves should be stripped and unruly branches cut off, or partially cut through, so that they will lie close. The larger, straighter brush should be laid on the outside, butts alternating in direction, and smaller stuff in the center. The general object is to so dispose the brush as to make the fascine of uniform size, strength and stiffness from end to end.
When the cradle is nearly filled, the fascine is compressed or choked by the fascine choker (Plate 30), which consists of two bars, 4 feet long, joined 18 inches from the ends by a chain 4 feet long. The chain is marked at 14 inches each way from the middle by inserting a ring or special link. To use, two men standing on opposite sides pass the chain under the brush, place the short ends of the handles on top and pass the bars, short end first, across to each other. They then bear down on the long ends until the marks on the chain come together. Chokers may be improvised from sticks and rope or wire.
Plate 30.—Method of using the fascine choker.
Binding will be done with a double turn of wire or tarred rope. It should be done in twelve places 18 inches apart, the end binders 3 inches outside the end trestles. To bind a fascine will require 66 feet of wire.
Improvised binders may be made from rods of live brush; hickory or hazel is the best. Place the butt under the foot and twist the rod to partially separate the fibers and make it flexible. A rod so prepared is called a withe. To use a withe, make a half-turn and twist at the smaller end. Pass the withe around the brush and the large end through the eye. Draw taut and double the large end back, taking two half-hitches over its own standing part.
