The manure thus liquified is made by a comparatively small number of animals.

Calves to the value of 50 pounds are bought, and fat stock to that of 500 pounds are sold annually.

They are all stabled throughout the year, except in harvest time, when they are turned out for a few weeks to rowen feed.

The calves are housed until a year old in a large stedding by themselves.

They are then transferred to another building, and put upon "the boards;" that is in a long stable or cowhouse, with a flooring of slats, through which the manure drops into a cellar below, made water-tight.
