GATE FASTENER. 
The Pastoralists’ Review gives the device here shown for securely fastening 
agate. The fastener is said to be very handy, most durable, and one which 
cannot be rubbed off by stock :— 
TOP RAIL 
OF GATE

THE GATE 
OTILE OF 
When A is pulled or pushed up, B necessarily falls on the bar of the cate at 
and stops A coming off the bar D. B must hang very loose, aaanorl ie 
tossed round so as to lie on top of A when opening the gate. B must hance 
yery loosely, and be made of flat iron, or else a notch put in the wood at C.
