3. Insecticides, fun- 

 gicides, and fertilizers 

 may be applied by means 

 of this system. 



4. It does not inter- 

 fere with plant growth, 

 because the water falls as 

 a fine mist or spray over 

 the plants. 



The cost of installing the system varies from $90 to 

 $150 per acre, and is as permanent as the piping used. 

 Water may be used from a reservoir or pumped directly 

 into the system. The greater the pressure, the finer is 

 the spray. The water is distributed by means of a gal- 

 vanized pipe fitted at intervals of three or four feet with 

 special nozzles; these and the machine for setting them 



are patented. See Fig. 

 3. The lines of pipe are 

 set from fifty to sixty 

 feet apart; and when 

 the pipe is supported 

 as in the illustration, 

 the posts are about 

 twenty feet apart. The 

 size of the pipe will of 

 course vary with the 

 distance and number of 

 nozzles on it. Fig. 5 

 shows the nozzles used;
