VEGETABLE GARDENING 



Figure 15 shows the position of the patented drilling 

 machine when in operation. This work must be done 

 with the greatest care. The nozzles, also patented, are 

 placed 4 feet apart for outdoor irrigation and 3 feet apart 

 for greenhouse watering. They must be in perfect align- 

 ment. Different nozzles (Figure 16) are used for green- 

 house a«id outdoor work. A patented union (Figure 17) 

 is also required for the installation of this system.
