PORTABLE FENCES AND HURDLES.
PORTABLE BOARD FENCES.
Figure 118 shows a very strong and secure board fence, composed entirely of ordinary fence boards. The triangular frames, which serve as posts, are each of two pieces of inch boards, crossed and braced as shown in figure 115. The panels, figure 117, are sixteen feet long, each composed of four boards, six inches wide. The space between the lower two boards is two and a half inches, second space three and a half inches. A convenient way of making the panels is to use three horses, like that shown in figure 116, the length of each being equal to the total width of the panel, and the three short upright strips marking the respective spaces between the boards. The top is covered with iron to clinch the nails used in putting the panel together. The boards are laid on these horses, and the upright cross-pieces nailed on. The second board from the top of each panel is notched at both ends, as shown in figure 117. A good way to make the triangular frames alike, is to cut the pieces by a uniform pattern. Then make one frame of the size and form desired, and at each of the three places where they are nailed together, fasten a plate of iron, thick enough to prevent the penetration of a common wrought nail driven against it. Now lay this pattern frame on the floor with the iron bolts uppermost. Then lay three pieces on this in exactly the right position, drive wrought nails through the two pieces and against the iron plates, which will clinch the nails firmly as fast as they are driven. This will enable the man to nail the frames together quite rapidly. In setting up the fence, each triangular frame supports the ends of two panels. The upper and lower boards of each panel interlock with the frame, as shown in figure 118, making a very strong fence. On open prairie or other wind-swept situations, it may be necessary to stake down some of the frames, to prevent their blowing over. This is quickly done by sharpening pieces of inch boards, twelve inches long, and one inch wide, and driving one beside the foot of the triangle, where it rests on the ground, and putting an eight-penny nail through both.
PORTABLE FENCES OF POLES OR WIRE.
Figures 119 and 120 show styles of portable fences, which are used to some extent in the territories. The base of each is the half of a small log, split through the center. For the fence shown in figure 119, two augur holes are bored a few inches apart, and small poles driven to serve as posts. Rails or round poles of the usual length are laid to the desired height, and the top of the posts tied together with wire. In situations where timber is less plentiful, a single stake is set into the base, as in figure 120, braced, and barbed or plain wire attached by staples. Besides the advantage of being easily moved, these fences can be prepared in winter, when there is little else to do, and rapidly set in place at any time when the ground is clear of snow.
Figure 121 is a fence made of either sawed stuff, or of rails or poles, having their ends flattened and bored. An iron rod, or piece of gas-pipe, anywhere from half an inch to an inch in diameter, is run through the holes, and through a base block into the ground as far as necessary. A round stick of tough durable wood, an inch or more in diameter, will answer. The size of this rod and its strength will depend upon the amount of zigzag that is given to the lengths. If the corners are one foot on each side of a central line, the fence firmly held together by the rods, will in effect stand on a two feet wide base. Less than this would perhaps sometimes answer, and there are no sharp corners, or deep recesses for weeds and rubbish.
PORTABLE FENCES FOR WINDBREAKS.
A fence that can be easily moved and quickly set up is shown in figure 122. It consists of panels made of strips eight or ten feet long, nailed to two by four posts, which are beveled to a sharp corner at the lower end. These panels are supported by posts, placed as shown in the engraving, and pinned to the fence posts by wooden pins, driven in by a light mallet. The panels are light and can be loaded upon a wagon from which the sides and ends of the box are removed. A box of pins and the mallet are all the tools required to set up the fence. This fence is not easily overthrown by the wind, which holds it down firmly when blowing on the face of it. For this reason in windy localities, the fence should be set facing the windy quarter.
Another good form of movable fence is seen in figure 123. It is made of common fence-boards, securely nailed on very light posts or on the edge of narrow boards and braced as shown in the engraving. This style of panel is largely employed by railroads as windbreaks in winter to keep the tracks from becoming covered with drifted snow. It is equally convenient on the farm, when a temporary inclosure is needed.
PORTABLE POULTRY FENCES.
It is often very convenient when poultry are inclosed during the growing season, to have a fence for the henyard which can be readily moved from place to place. The illustration, figure 124, shows one of these. Cut the posts the same length as the pickets, and to the inner side of each attach two strong iron hoops bent into a semi-circle, one near the bottom and the other half way up. Through these hoops drive stakes fitted to fill them closely, with sharpened points for easily entering the ground. When removing the fence the posts can be slipped off.
Turkeys, even when they have attained a considerable size, should be shut up until after the dew is off the grass, and other fowls must be confined in limited runs, while the young are small. It is quite an advantage if these runs can be changed easily, and this can be accomplished only when they are enclosed in a light movable fence. Such a fence is shown in figure 125, on preceding page. It is made in twelve or sixteen feet sections by nailing laths to light pieces of the proper length. The upper end of the laths is sharpened; the end ones are of double thickness. The sections are placed with the end-laths intercrossing at the top, and about six inches apart at the bottom, as in cross-section, figure 126. They are held apart by blocks, figure 127, which rest on the upper edges of the cross-pieces and against the laths. They are held together, and to the ground, by stakes driven against the outer side of the end laths. As these stakes have the same angle as the laths, they hold the sections together, and also the fence in its place and down to the ground. The triangular space where the sections join is closed by a lath driven in the ground or tacked to the block between the cross-pieces. Corners must be formed of two sections inclined inward, and in the same way that sections are joined. The stakes are readily withdrawn, and the sections are so light that they are easily handled.
PORTABLE FOLDING FENCE.
A very convenient form of portable fence or hurdle is illustrated in figures 128, 129 and 130, which was brought out some five or six years ago. It may be constructed with two or three upright pieces of two-by-four-inch scantling, and four bars, figure 128, held together by carriage bolts in such a manner, that each panel can be closed when desired, as a parallel ruler is folded together. As the bars are on alternate sides, the panel, when closed, takes up the space of two bars only, figure 129. The fence may easily be removed, and fits itself to rolling ground or side-hill, as shown in figure 130. When in position it may be supported by stakes of the same thickness as the upright bars, and driven close beside them.
TEMPORARY WIRE AND IRON FENCES.
Several kinds of wire and iron fences are used in France to make temporary enclosures for exhibition purposes. Two forms are illustrated herewith. Figure 131 is made of plain iron wire with cast or wrought iron posts. Each post has a plate on its lower end, which is set eighteen inches below the surface of the ground, and the earth filled in compactly about it. The front of the engraving shows the holes in section, with the plates. The top strand is a wire rope made by twisting several strands together. The fence seen at figure 132 is made of narrow strips of sheet iron attached to iron posts driven into the ground. The gate, like that of the other form, is provided with small wheels, which run on a track. The two fences may be modified by using wooden posts sharpened at the lower end, and driven into the ground, then fastening to them with suitable staples strips of rather broad hoop-iron at the top, with plain wire below.
