They must, however, be wide enough to admit of nailing two hinges on each post. The fence consists of two parts—E in [figure 31] represents a cross-section of the fence proper, two panels of which are seen in [figure 34]; D represents the back part of the fence, a section of which is shown in [figure 35]; a in [figure 31] is the post and b b the hinges. The panel, E, should always slope with the current of the stream, that the water rushing against it will place it in the position shown by [figure 33], lying flat on the ground, and out of the way of both water and drift. The hinges may be ordinary strap kind, which can be bought very cheap by the dozen, or they may be made of heavy iron hoop doubled, as shown at [figure 32], which can be made in any blacksmith shop.
