Plate 31.—Fascine revetment.
A fascine revetment is made by placing the fascines as shown in Plate 31. The use of headers and anchors is absolutely necessary in loose soils only, but they greatly strengthen the revetment in any case. A fascine revetment must always be crowned with sod or bags.
In all brush weaving the following terms have been adopted and are convenient to use:
Randing.—Weaving a single rod in and out between pickets.
Slewing.—Weaving two or more rods together in the same way.
Pairing.—Carrying two rods together, crossing each other in and out at each picket.
Wattling.—A general term applied to the woven part of brush construction.
A hurdle is a basket work made of brushwood. If made in pieces the usual size is 2 feet 9 inches by 6 feet, though the width may be varied so that it will cover the desired height of slope.
A hurdle is made by describing on the ground an arc of a circle of 8-foot radius and on the arc driving ten pickets, 8 inches apart, covering 6 feet out to out. Brush is then woven in and out and well compacted. The concave side of a hurdle should be placed next the earth. It warps less than if made flat.
