62 PROFITABLE PIGEON BREEDING 



pipe will very naturally How upwards because of the fact that 

 it has pressiu'c behind it. 



Let me explain this s>stem. By the use of a two pipe system 

 we get a main feed pipe and a return main. Each fountain 

 is connected to the feed main and to the return main inde- 

 pendentlj- of the other fountains. One may shut the valves off 

 at any fountain and not disturb the flow to any other fountain 

 at any time. This is a decided advantage. Wliere the system 

 is installed and ready for use A\e turn on a control valve at 

 the junction of the supply main and the main from the street, 

 having previously opened up each angle needle valve at the 

 fountains so that there ^\•ill be a constant drip into the foun- 

 tains. The fountains fill up in due course of time and as they 

 do so the overflow pipes start to function and carry off the sur- 

 plus water. These fountain valves can be so regulated tliat it 

 will be impossible to overflow a foinitain. Thus there is a never 

 ceasing flow of water in the system through the fountains at 

 all times until we cut off the control valves. In this way a 

 fresh cool and clean sujiply of water is ever before the birds. 



By tlie construction of these fountains the birds cannot foul 

 the water in any way whatsoever as they cannot get to the 

 water only to drink it. 



The feed and return mains should be buried from twelve to 

 eighteen inches according to the freezing depth in any locality. 



The fountain is so constructed that it can be lifted away from 

 the supply pipe and up from the return pipe in order that we 

 can take it out and scald it thoroughly. This is a mighty good 

 idea. Then too, by removing the fountain as I have just men- 

 tioned, there are no connections to be loosened with a wrench, 

 we can slip the bath pan under the supply pipe and All it for 

 .the bath. 



It is my opinion that this system will be a great help to £iny 

 breeder that can install it. It should not cost so very much at 

 this time, for the plumbing materials necessary for its installa- 

 tion have gone down in price considerably.
