 tree ; and in this cale the pivot muft be placed 

 not in the center, but on the outfide of the

 behind the pin of the upper hook, to give the 

 gate a fall when open at right angle ; and 

 the latter, to throw the point of the pivot 

 fvithout the pin of the hook, to give the gate 

 a fall at the pod, and make it catch with cer- 

 tainty. 



This being underftood, it is eafy to con- 

 ceive that if the lower end of the hartree be 

 crooked, and if the elbow or convex fide of 

 the bend be directed not to cither pofl, but 

 towards the middle of the gateway, the nc- 

 celTary falls may be had without throwing 

 the gate out of the fquare, or the pivot out 

 of the center of the hartrcc.

 calion to fpeak fully of the method of hanging 

 gates on hooks,
