convenient."

"I'm afraid that last method would not do at all for the dairy
farmer," said Mr. Thornton. "You see we have to keep things very
clean and in sanitary condition."

"Most often the cleanest and most sanitary method the average farmer
has of handling the manure in dairying," said Percy, "is to keep it
buried as much as possible under plenty of clean bedding; and one of
the worst methods is to overhaul it every day by 'cleaning' the
stable, unless you could have concrete floors throughout, and flush
them well once or twice a day, thus losing a considerable part of
the valuable excrement. If you allow the manure to accumulate for
several weeks at a time, it is best to have sufficient room in the
stable or shed so that the cows need not be tied. If allowed to run
loose they will find clean places to lie down even during the night.

"In case of horses, the manure can be kept buried for several weeks
if some means are used to prevent the escape of ammonia. Cattle
produce what is called a 'cold' manure, while it is called 'hot'
from horses because it decomposes so readily. One of the best
substances to use for the prevention of loss of ammonia in horse
stables is acid phosphate, which has power to unite with ammonia and
hold it in a fixed compound. About one pound of acid phosphate per
day for each horse should be sprinkled over the manure. Of course
the phosphorus contained in the acid phosphate has considerable
value for its own sake, and care should be taken that you do not
lose more phosphorus from the acid phosphate applied than the value
of all the ammonia saved by this means. Porous earth floors may
absorb very considerable amounts of liquid from wet manure lying
