REMODELLING OLD BUILDINGS 37 



them are likely to soon wear out or get out of order, 

 being exposed to high winds and gales, and they are now 

 being replaced by gasoline or hot-air engines; when an 

 engine is properly installed, well protected, and care- 

 fully used, it will last a long time and the water supply 

 is insured whether the wind blows or not. 



Purity of the Water. 



Town and city water supplies are generally carefully 

 inspected by local authorities or state officials and are 

 safer than water from local wells or basins. Before any 

 water supply is used freely it should be carefully in- 

 spected and if any doubt exists as to its purity samples 

 should be sent to experiment stations, state boards of 

 health, or other authorities whose duty it is to analyze 

 such supply. 



Bath-rooms, hot and cold water, and water-closets 

 should be put into every country home, wherever pos- 

 sible. These can be arranged in a small space, and if 

 the water cannot be supplied in any other way, a good 

 force-pump will do the work of supplying the tank in 

 the attic in an hour or two each day. A very small 

 expenditure for so great a luxury. 



Sanitation. 



Wherever waste water is carried into cesspools or 

 vaults the pipes must be provided with proper traps 

 and escapes to prevent the 

 gas from these places from 

 entering the buildings t - ^r 

 (Fig. 5). All traps should I 

 be placed where they may be 

 easily gotten at and cleaned 

 out in case of stoppage, and
