(β) Rinsing with quartz gravel by means of a stream of hot water.
(γ) Cold rinsing.
(δ) Sterilization in the dry chamber. These cleansing manipulations occupy about forty-five minutes.
III. The stable itself should be so built that it can readily and thoroughly be cleansed, with special regard to the following points:
(a) Draining of the fluid excreta, etc., by means of drains with sufficient pitch.
(b) Ready removal of solid refuse without raising dust.
(c) A plentiful supply, by means of pipes, of pure, wholesome water. Also a hot-water supply for cleansing purposes.
(d) Good ventilation for the high lying stalls.
(e) Broad alleys separating the rows of stalls.
(f) Each stall to be constructed in such manner that the cow is obliged after feeding to step back, thus compelling her to empty her excreta into an open drain connected with the main drain. This is effected by means of the so-called “drop-railing contrivance.”
