Milk, cheese and butter, a practical handbook on their properties and the processes of their production . t of a body of foulair in proportion to its bulk, which enters the dairy when the trap iswithin it.

The syphon kind shown in Fig. 29 is the best and simplest, butneeds frequent removals of solid mattersettling in the bend.

The sliding door c cuts offthe outside air when the immediate useof the drain is over ; a brick sink-well if,18 inches square and a foot deep, re-ceives the waters, which then pass throughthe strainer e into the trap / and the head of every branch drain thereshould be a ventilating pipe, which willcarry the gases far enough above thewindows of the lower floor to make sureof their complete dissipation at a safepoint ; and this should end in a revolving cowl, which will discharge.

At convenient intervals openings should be provided for reachingand removing any obstructions. Whenever a stoppage occurs, waterpoured down may be followed at these inspection holes, and the sectionof the drain in which it is will be known by the water failing to appearat the inspection hole below it. These holes should be large enoughto admit of a drain-clearing tool being put together, section by section,within the drain, as shown in Fig. 30, and this tool should be longenough to reach half-way between any two holes, so that if the clawdoes not strike the obstruction from the point of entry above, it may besure to do so from the one below it. The cost of this provision is notmore than any probable years expenses in curing the stoppages inordina
