WATER IN CAMP

the flow, destroy the siphon and possi- 

 bly stop it all together, even though the 

 air has been forced out at the start. 



B, in the same figure, has a bend, but 

 in the opposite direction. In this case 

 air cannot pocket as it will seek one of 

 the high points and pass out. In the 



fig. 4 



city supply the pressure is so high that 

 any air that may get in the pipes is 

 forced out when the valve is opened. 

 The high pressure allows the use of 

 small pipe, but in the low pressure 

 system, in connection with a spring, 

 large pipes must be used or the water 

 will run very slowly. 



Figure 5 illustrates an installation 

 in use which operates well, although 

 the top of the stove tank is but a few 

 inches below the water level in the 

 spring. The pipe line from the spring 

 to the house consists of one hundred 



and fifty feet of one and one half inch 

 pipe. The spring is at (A), the pipe 

 line enters the house at (V) where 

 there is a valve that has an opening or 

 cross section almost equal to that of the 

 pipe. 



When the water is let into the pipe, 

 this valve is left wide open, which 

 causes such a rush in the water that 

 any air that may be left in the pipe 

 is dragged through and passes out. 



The pipe was carefully laid and tried 

 with a spirit level to get the fall in the 

 line constant, but air will stay in the 

 pipe when water is admitted if the 

 valve at (V) is not open.

FIG. 5 



The building was located to suit the 

 level of the spring and the bathroom 

 placed on the ground floor. At (O) on 

 the pipe carrying the water from the 

 stove tank to the basis and tub is an 

 elbow and a piece of one and one-half 

 inch pipe standing perpendicular and 

 passing eighteen inches above the 

 water level. 



LIFE'S GOAL 



By NANNIE BURNS. 



A pure, sweet spring gushed forth from Thus some innocent, guileless thing, 



granite rocks, Growing in a world of death and sin, 



The bow of promise spanned its glistening Blossoms into beauty of soul through love, 



drops, Shed like the rainbow from the Light above ; 



A silvery rill, from bondage free, 



To wander on to its goal, the sea. 



And fulfilling the promises of the rill, 

 Tho' it may wander whither it will, 

 At last it reaches the open sea, 

 It reaches the sea of Eternity.
