In the farm buildings, the fittings up of the poultry-houses, the rabbit-house, and the dairy and scullery, well deserve attention; and also the arrangement for fermenting the food of the pigs in underground cisterns, not too warm for summer, nor so cold as to check fermentation in winter. The manure of the horses, of the cows, of the pigs, of the rabbits, of the pigeons, and of the poultry, is kept in separate pits, that it may be used, if desirable, in making up different composts.
