But, secing that from time immemorial this nuisance of left-open gates has 
existed, and wil! doubtless continue to exist, the next best thing is to construct 
a gate which shall be “immune” to such carelessness. There are, of course, 
cireumstances under which it would be as wrong to close a gate as to leave it 
open, as, for instance, when.a mob of cattle, horses, or drove of sheep is being 
brought out of a paddock and the gate has been purposely left open by the 
owner. A very good rule to observe on entering a neighbour’s grourd is to 
leave gates as you find them, as you cannot tell whether you will be doing right 
or wrong in closing them. Now here is a device given in the Farmer and 
Stockbreeder (London), which, if applied, will save the devout farmer from 
thinking hard things of his visitor who does not close his gate :— 
The contrivance is simply a link in two parts, hinged together as shown in 
the illustration. When fixed to a gate-post the under part of the link (B) 
projects slightly. As the gate strikes the post the impact causes the upper 
part of the link (A) to fall over, thus securing the gate to the post. By simply 
lifting the link, the gate is unfastened. On gates swung to close themselves, 
the link arrangement works admirably, and the gate can easily be opened by a 
horseman without his dismounting, and he is furthermore saved the trouble of 
dragging a restive horse about in his endeavours to get him into a pesition 
which will allow of his closing the old-fashioned clip. 
HOW TO CALCULATE THE WEIGHT OF LIVE STOCK. 
- 1. Ascertain the girth, in inches, back of the shoulders, and the length, in 
inches, from the square of the buttock to a point even with the point of the 
shoulder-blade. ; 
9. Multiply the girth by the length, and divide the product by 144, to 
arrive at the superficial fect; then multiply the superficial feet by the number 
of pounds per foot for cattle of different girths, the product of which will be 
the number of pounds of beef, veal, or pork in the four quarters of the 
animal. tH thy 
3. For cattle of a girth of from 5 to 7 feet take 23 Ib. to each superficial 
foot; and for a girth of from 7 to 9 feet, 31 lb. to the superficial foot. 
4. For small cattle and calves of a girth of from’ to 5 feet, 16 lb. to the 
foot; and for sheep, pigs, and all cattle measuring less than 8 feet, 11 lb. to the 
superficial foot.
