with a gunny sack and with a long -handled basin 



dextrously bales the water out as rapidly as it reaches 



him, dashing it over 



the littered surface

ends of the beds have 



been reached, when the head ditch is opened and 



closed in another place, turning the water in between 



other beds. 



When the water has had time to penetrate the

 and the delicate plants have begun to emerge from

Another type of irrigation is shown in Fig. 113, 

 where the garden is ridged and furrowed every 18 

 inches. Celery is planted on one side of each ridge

 from a stream led along their head, and these, when
