Fig. 28.—Panel.

The fence illustrated in figures 28, 29 and 30 has posts the usual distance apart, which are hewed on the front side, and on this are nailed three blocks, three by four inches thick and six inches long; the first one, with its top just level with the ground, the second one, ten inches in the clear above, and the third one, four inches less than the desired height of the fence, measuring from the top of the first block. After the panel is put in place, the rounded ends resting on the bottom blocks, nail a piece of board one and one-half by six inches on the blocks, as shown in the illustrations. This board must project four inches above the upper block, forming with it the rest and catch for the top framing piece of the panel. The panel is made of a top and bottom piece of three by four scantling, on which are nailed palings.

The top piece is left square, and projects three inches on each side, but on the bottom piece the projections are cut round, so as to turn in the slot. The water will raise the panel up out of the upper catch, allowing it to fall down, as seen at figure 30, so as to offer no obstruction to the water, nor will it catch drift, as fences hung from the top do. Figures 31 to 35 represent a fence made somewhat like the trestle used for drying clothes. The posts are the usual distance apart, but only extend a few inches out of the ground, just sufficient to nail a hinge upon.

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.
