Rafters can alsO' be of same material as studding, but not less than 

 2x5 in size for a shingle, steel, or galvanized roof, and 2x6 ifslate are used 

 ifior roofing, depending somewhat on the width of building. A shingle 

 roof seems to give the best service for a creamery, it keeps the building 

 cool in summer and warmi in win ter. As far as durability or being fire- 

 proof is concerned, a slate roof is far superior. 



Siding miay be' 5 inch popular lap or pine drop siding, the latter being' 

 the cheapest. 



The building should be celled entirely on the inside with yellow 

 pine ceiling, except the boiler room which should be lined with corru- 

 gated iron or made of brick. Two dead air spaces can be cheaply conr- 

 structed on the entire building, by putting building paper up and d'own 

 ■on the studddng, nailing over this 1 inch by 2 inch strips and ceil on 

 s/trips. Papeir must be secured at to-p and bottom so that a perfect dead 

 air space is the result. Lath and plaster may be used' as a substitute 

 for paper but at a greater expense. 



The Drain. If a cement floor is used, the floor should' slant % inch 

 to every floot from all directions toward one point, the inlet to the un- 

 derground drain, at which point a bell trap should be connected, to pre- 

 vent the odors from the sewer from coming up into the factory. 



If a creamery is to be built with wood floors it is always best tO' use 

 a gutter set into the floor for the drain. This can be constructeidi by 

 placing two joists about 4 inches apart, and letting them- extend the full 

 length or width of' the building. Cut the floor flush with the edge of 

 each joist. Rabbit these ends % inch on each side and paint with white 

 lead, then lay in a coating of putty and form the gutter of galvanized 

 iron or preferable copper, so that it will set down in between joist, and 

 turn over where the floor is rabbited, nail into the floor, driving the nails 

 close together, then give it another coat of white lead and putty again. 

 The slant of a wood floor should be the same as that of a cemeint floor,, 

 and the gutter itself should also have the same slant toward the trap. A 

 cast iron gutter may be usedi in place of galvanized iron or probably best 

 of all for a wood' floor is a gutter worked out of a solid piece of wood, 

 well oiled before it is put in plaoe.
