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.
