Irrigating from Water- Mains. — In describing 

 an experiment with irrigation in Eastern Kansas, B. F. 

 Smith, of Lawrence, says : "I laid iron pipe on top of 

 the ground along the roadways through a strawberry 

 patch of two and one-fourth acres. Three hundred of 

 the five hundred feet of pipe used is common inch iron, 

 and two hundred feet is half-inch galvanized iron pipe. 

 At intervals of about one hundred feet are water-cocks, 

 or faucets, for attaching a three-fourths inch rubber 

 hose. This hose, being one hundred feet in length, 

 enabled me to reach the entire berry patch. Beginning 

 at the first faucet I watered all within reach of it, then 

 moved the hose to the second faucet, and so on, till the 

 whole patch was watered. At the commencement of 

 the experiment I used a nozzle in the manner that we 

 water our lawns, but soon discovered that the better 

 way was to dispense with the nozzle, and let the water 

 run out on the rov^ of berries from the end of the 

 open hose. Water was applied at the rate of about a 

 gallon to every twenty inches in length of row. This 

 amount of water thoroughly soaked the rows, but not 

 the entire space between the rows, which is not neces- 

 sary to the well-ripening of berries, as the water-supply 

 is wanted among the roots. Then, to have watered 

 the two-feet space between the rows would have taken 

 double the amount of water, with no addition of fruit. 



* * The irrigation was all done at night. The time 

 taken to go over the patch was twenty-eight hours.
