a dependable water supply, as it will require no fuel 

 for its power. 



When one of the various engines must be em- 

 ployed one has the advantage of pumping the water 

 direct from a good well. An artesian well, driven 

 through earth and rocks to a deep source of supply, 

 until water is procured that is pronounced chem- 

 ically pure, will give the best results ; and the type 

 of engine best for pumping it up to the supply tank 

 will depend on the situation of the home. When one 

 resides in a district covered by a company distribut- 

 ing the electric current, or near a trolley line where 

 arrangements can be made with the management 

 for the necessary power, an electric motor will 

 probably prove to be the simplest apparatus to ope- 

 rate. The best plan in this case is to install a water 

 pump of centrifugal form. When directly connected 

 to a small electric motor this pump can be operated 

 at a comparatively high efficiency, and it can be de- 

 pended upon for instant service, at the same time 

 being clean and compact. Its cost and maintenance 

 will not be prohibitive if good judgment is used in 

 making arrangements at the source of supply. The 

 wise householder will secure low rates by arranging 

 to do his pumping at an advantageous time, when 

 special demands are not required of the electric cur- 

 rent for lighting and other purposes. When modern
