152 AROUND THE YEAR IN THE GARDEN 



SO that the whole space to be irrigated is watered at one 

 time. 



For the vegetable garden, at least one nozzle line the 

 length of the plot should be fitted up. As the nozzles 

 throw twenty-five feet in either direction, the pipe being 

 turned from side to side, this line will cover a strip fifty 

 feet wide. If the garden is wider than this another line 

 may be added or the first one may be built in sections of 

 convenient length to move. A twenty-foot length of three- 

 quarter-inch pipe weighs only about twenty-five pounds. 



At the head of each line of nozzles there should be a gate 

 valve to control the water, and a turning union. The older 

 types of nozzles were somewhat given to clogging up, but 

 in the newer ones this diflQcuIty has been largely overcome. 



The various items required for a line of the nozzle system 

 are: Gate valve, seventy-five cents; turning union and 

 handle, $1.75 to $3, according to type and finish; nozzles, 

 inserted every three or four feet in the pipe, five cents 

 apiece; and three-quarter-inch galvanized pipe, six to 

 eight cents a foot. To get your nozzles in perfect aUgn- 

 ment along the pipe you need a special drill fitted with a 

 level with which holes are driUed after the pipe is in place. 

 For a few hundred feet of pipe for a garden you can have the 

 holes drilled and the nozzles inserted where you buy the 

 pipe. 



The two great advantages of watering with overhead 

 irrigation are the tremendous saving in time and the fact 

 that the water is applied in an ideal way, falling in small 

 drops that do not pack the soil or spatter or injure foliage 

 or blossoms.
