TO ASCERTAIN THE WEIGHT OF CATTLE.

Measure the girt close behind the shoulder, and the length from
the fore part of the shoulder-blade along the back to the bone at
the tail, which is in a vertical line with the buttock, both in feet.
Multiply the square of the girt, expressed in feet, by five times the
length, and divide the product by 21; the quotient is the weight,
nearly, of the four quarters, in imperial stones of 14 lbs. avoirdu-
pois. For example, if the girt be 6 feet, and the length 5 1/4 feet, we
shall have 6 x 6=36, and 5 1/4 x 5=26 1/4; then 36 x 26 1/4=945, and this
divided by 21, gives 45 stones exactly, or 45 x 14=630 lbs. It is to be
observed, however, that in very fat cattle the four quarters will be
about one-twentieth more, while in those in a very lean state they
will be one-twentieth less than the weight obtained by the rule.

To Estimate the Amount of Hay in a Mow.

A gentleman largely engaged in the growing of hay and stock in
Orange County, N. Y., writes: "In this part of the country we sell
hay by measurement, in a mow, and allow 512 cubic feet for a ton,
and it comes out very generally correct. I have just sold a mow of
hay and weighed it, and measured the mow, and this rule proved
correct."

The above rule no doubt approximates as closely as possible to a
correct standard, the number of cubic feet required for a ton vary-
ing a little on account of the different degrees of pressure to which
the hay has been subjected, and also with the quality of the hay as
regards fineness.
