PROVIDING POXDS 



A plan for a pond to furnish drinking water has lieen 

 sug-gested by the ( )klah(^ma experiment station (Bulletin 

 Xo. 66) as follows: 



"A pond that is to furnish drinking water for stock 

 should be fenced and the stock be kept out. They should 

 drink from a tank supplied with water from the pond 

 through a pipe under the dam and leading to the bottom 

 of the pond. In building a pond, one of the first steps is 

 to place the pipe that is to conduct the water from the 

 ])ond to the tank where the stock is to drink. This pipe 

 should be put into the ground about two feet and ex- 

 tended 12 or 15 feet beyond the line where the bottom 

 of the dam will come on the inside. Special pains should 

 be taken to pack the earth well in the trench around the 

 pipe, for if this is not done, water is very likely to seep 

 out under the dam through this ditch, and a seep like this, 

 once started, is almost impossible to stop. A i'4 inch 

 pipe should be used. On the end in the pond, an upright 

 j)iece of pipe that will extend two or three feet above the 

 bottom of the pond should be attached. A substantial 

 screen of some kind should be put over the end of the 

 upright pipe. A cast guard such- as is used on the bot- 

 tom of a pipe in a well is good for the purpose, but 

 should not have the gau^^e screen inside that is commonly 

 used in the well. The guard may be wrapped outside
