 inches deep, ahhough it contain no more than lialf the 

 timber. 



In the ground pJan, or horizontal fe^lion, Fig, 7. reprefents 

 a piece of wood, about four inches cube, pinned to the 

 falling poft, a little below the catch, to ftop the gate from 

 fwinging be)'ond the poft : another ftop near the ground may 

 be ufeful. 



When gates are hung to open one way only, their heels and 

 heads generally reft againft the hanging and falling pofts; 

 but when they are hung according to this defign, gates may be 

 made about one foot fliorter for the fame opening, and confe- 

 ^uently they muft be lighter, ftronger, and lefs expeiifive.

Hanging of When the two hooks in the hanging-poft are placed in tl>e 



gates. fame perpendicular line, a gate, like a door, will reft in any 



direction in which it may be placed. But, in order that a gate 

 may ftiut ilfelf when thrown open, the hooks are not placed 

 exactly perpendicular; the upper hook declining a little to- 

 wards the falllng-poft, or a few feet beyond it. In whatever 

 diredion that hook declines the fartheft, in the fame dire6iion 

 will the gate reft, if unobftrufted, and its head cannot then 

 fink any loWer. Make the head defcribe half a circle, and it 

 will thus have attained its utmoll: elevation, and will be 

 equally inclined to defcend either to the right or to the 

 left*.
