heated with stoves, the bathroom can best be arranged to 

 adjoin the kitchen, and the heat therefrom ought to prevent 

 the freezing of the water in the pipes. For this reason the 



pipes should be protected 

 as far as possible from the 

 cold. It is not best, how- 

 ever, to place them in the 

 wall, as exposed pipes are 

 decidedly more convenient 

 to repair. One very satis- 

 factory method of caring 

 for the pipes is to pro-vide 

 a conduit with a removable 

 cover, which may be panel- 

 ed in such a way as not to 

 detract from the appear- 

 ance of the room. All of 

 the fixtures requiring 

 drainage should be clus- 

 tered about the soil pipe 

 which should extend from 

 the cellar up through the 

 building and out through 

 the roof for ventilation. 

 This soil pipe is univer- 

 sally made of four-inch 

 cast-iron pipe with fittings 

 inserted at proper places 

 to receive the drainage 

 from the various fixtures. 

 It is best that a clean-out plug be provided at the bottom. 

 At a slight additional cost, hot water may be provided. 

 All that is required in addition is a hot water or range tank
