LIQUID MANURE ON THE FARM.

I have never had any personal experience in the use of liquid manure to
any crop except grass. At Rothamsted, Mr. Lawes used to draw out the
liquid manure in a water-cart, and distribute it on grass land.

"What we want to know," said the Deacon, "is whether the liquid from our
barn-yards will pay to draw out. If it will, the proper method of using
it can be left to our ingenuity."

According to Prof. Wolff, a ton of urine from horses, cows, sheep, and
swine, contains the following amounts of nitrogen, phosphoric acid, and
potash, and, for the sake of comparison, I give the composition of
drainage from the barn-yard, and also of fresh dung of the different
animals:

The drainage from a barn-yard, it will be seen, contains a little more
than half as much nitrogen as cow-dung; and it is probable that the
nitrogen in the liquid is in a much more available condition than that
in the dung. It contains, also, nearly five times as much potash as the
dung. It would seem, therefore, that with proper arrangements for
pumping and distributing, this liquid could be drawn a short distance
with profit.

But whether it will or will not pa
