For the admission of the screws a strong iron arch is placed in the corner of the gate, and fastened at each end with screw-nuts; its range down the heel-post Fig. THE WIRE FIELD-GATE WITH RAYED UPFILLINGS. as compared with that along the upper rail, should be as the length of the gate is to its hight, which in this example, is 18 inches down the heel-post, and 6 inches along the upper rail. A gate of this form, and 9 feet bj' 3^ feet, costs £1 ;* (1980.) The wire-gates above described are admirable examples of the principles of trussed frames, and for gates. So far as that principle gives them firmness and support, they can hardly be excelled ; but there is one defect attendant upon the wire upfilling. its too great tenuity, which renders the wires liable to derangement on being loaded with any cross-strain, such a person attempting to climb over the gate, and setting foot oli the wires. A diagonal wire undergoing such treatment will be liable to stretch, and thereby lose its effect. Could such accidents be effec- tually guarded against, these gates might be regarded as almost perfect. In regard to the expense of the gates first described, the common wooden field-gates may be considered to range from 15s. to 25s. The gate, fig. 355, about £\ ISs.; and the selling price of the angle-iron-gate, fig. 356, is about Xl 5s. (1981.)
