There are many otherwise good cement floors that are 

 ruined by spilling acid on them. If acid is ever spilt, or used in 

 cleaning the floor, it should be diluted with at least ten parts of 

 water to one part of acid, and must be immediately washed off 

 to prevent damage to the floor. Salt is also injurious to a 

 cement floor, and any unnecessary spilling of salt on the floor 

 should be avoided. 



The Drain. 



The drainage system inside of the building should be com- 

 pleted before the floors are laid, and it is advisable to have a 

 drain pipe to every part of the building where there is any waste 

 water. The trap in the engine room should be located near the 

 side of the boiler, in order that the waste water from the pump 

 and injector may be taken care of. A small trap should be lo- 

 cated under the cylinder of the engine. The floor within one 

 foot of this trap should be somewhat lower than the rest of 

 the floor, as this will prevent oil from running all over the 

 floor, and allowing this trap to take care of it. There should 

 be a small groove in the cement floor around the base of the 

 engine. This will take care of any oil and waste water from 

 the engine; leading it to the trap under the cylinder. The con- 

 densed water from the engine cylinder should be piped through 

 the floor and into the sewer, thus doing away with the old 

 method of having it splashing over the floor. The drainage 

 from the wash sink should be piped through the floor directly 

 into the sewer with a trap, as per diagram. The exhaust from 

 the tester should be taken care of by running a two inch pipe 

 through the floor and into the sewer. The diagram will show 

 the various other places in the building where drain traps should 

 be located, and by studying the diagram any one. may easily be- 

 come familiar with the drainage system. For the main drain, 

 at least an 8 in. tile should be used, while the drains branching 

 out to the engine room and ice box or other places in the build- 

 ing may be made with 4 in. tile. 



It is best to use a good quality of glazed tiling in construct- 

 ing the drainage system ; such a tile may cost a little more money
