Veterinary hygiene. 876 VETEEINAEY HYGIENE We are considering cesspits and liquid manure tanks together, for though known by different names they are identical, one being the farm cesspool, and the other the cesspool of the ordinary residential house. It is with the former that we have to deal and to discuss how it can best be arranged. The drainage from farm stables, cow-sheds, piggeries, and covered yards, constitute one of the farmer's sources of income. It is imperative in the case of cow-sheds that the drainage shall be on the most approved principles, surface throughout, and no traps of any kind within the building.

The urine in a cow-shed is discharged by the animal practically direct into the surface drain and the bulk of the faeces find their way there also; what fails to reach the drain is swept into it, and the whole contents pass out of the shed into the outside air. It should then pass into a concrete receptacle, 12 feet from the building, one for either side of the byre (Eig. 130), from which it is removed by pumping into the liquid manure cart, and from this deposited either in the covered shed for manure, or dis- charged into the liquid manure tank. This carriage by hand may be modified by the cow-shed surface drains opening over a properly trapped drain 12 feet away from the building, and the urine and suspended fseces Digitized by Microsoft®.
