In the ground plan, or horizontal Section, Fg. 7 represents a piece of wood, about four inches eube, pinned to tbe falling pos, a Jittle below the catch, to stop the gate from Swinging beyond the post: another Stop near the ground may be useful.

When gates are hung to open one wäy only, their heels and heads generally restagainst the hanging andtalling posts; but when tbey are hung according to this deeign, gates may be made about one foot Shorter for the Same opening, and consequently they must be lighter, Stronger, and less CXPENSIVE,

Of the hanging of Gates.

When the two hooks in the hanging-post are placed in the Same perpendicular line, a gate, like a door, will rest in any direction in which it may-be placed. But, in order that a gate may Shut itself when thrown oper, the hooks are not placed exactly perpendicular; the upper hook declining a little towards the falling-post, or a few feet beyond It. In whatever directiod that hook declines the farthest, in the Same direction will the gate rest, 18€ unobstructed, and its head can- pot ihen ink any lower. Make the head describe half a cir- dle, and it will thus have-attained its utmost elevation, and will be equally iaclined to descend either to'the right or to

the left.*

ceding design, and that the lower hook must be four feet and 1

and at four feet and a half mark the post; then at one Inch and a half farther from the gateway than this mark, drive in the lower hook; this book must project about half an inch farther from the face of the post, than the upper hook. In the

etion or ground-plan of the gate, the two white circles near the hanging-post, represgentthe places ofthe two hooks, when brought to the Same horizontal line; that nearest the gateway represents the place ofthe upper hook. A line drawn through the middle of these two eircles, and extended each way, will, on one hand, represent the gate's natural.line of rest, and, on the otber, tbe line of.its highest elevation. A gate thus bung
