A CLEAN TAIL. 
The simple device here illustrated can be used in nearly every cow stable: 
to keep the tails clean and prevent the cows from switching during milking in. 
fly time. A piece of heavy cord, with a loop in each end, is fastened above- 
the cow at a, and the other end slipped round her tail as shown. When she 
lies down this will keep her tail out of the gutter and filth. When about to 
milk, hang the cord over a beam or hook at 6, which will pull the tail above 
harm’s way.— American Agriculturist. 
A DEVICE FOR MEASURING LAND. 
Take three strips of batten 2 inches wide, 3-inch thick, and 6 feet long,” 
and nail them together, as shown in the accompanying engraving. After 
fastening them together, saw off the ends so that the air-line distance from A 
to B, from B to C, and from C to A shall be exactly 53 feet. A man can stand 
erect in using this, and roll it over at a walking gait, each revolution measuring: 
1 rod. In commencing, place B at the starting point, letting C be in the 
direction you are to measure, and A pointing upwards. A coloured tag should. 
mark A to remind you to count one each time it comes pointing upwards. The 
advantage of this shape over that of a common triangle is that it permits 
straddling over slight objects or elevations, and thus does not measure the 
circuitous distance over them, a fault of all wheel measures. This measure is: 
very light, a rapid worker, quite accurate, and requires no stooping on the part 
of the operator.—American Agriculturist.
