be economy to do this not only from the fact that a 

 double supply is thus obtained, but because when the 

 fire is allowed to go out at night it takes about an hour 

 to get the pump to running again. By continuous 

 running, time is saved at both ends of the day. 



In applying the water to a field of cabbage or cauli- 

 flower, the rows being about three and a half feet 

 apart, a plough is run between the rows, so as to make 

 a furrow for the water to run in. It is a very easy 

 matter to water a field where the land is on a slope, but 

 where it is nearly level it is much more work ; as the 

 hose has to be frequently transferred to different points 

 in order to water evenly. 



In watering a field of celery a furrow is ploughed 

 away from the plants, on each side of the row, at a 

 distance of about one foot. The furrow is then filled 

 with water; and as soon as this has soaked away the 

 furrow is turned back again. An application of this 

 kind once a week will prove sufficient even in the 

 dryest time. 



The crops which require the most water, and those 

 which therefore are most benefited by irrigation, are 

 cabbage, cauliflower, celery, lettuce, beets, cucumbers, 

 horse-radish, and, in some cases, squashes. 



The practice of irrigation in this manner has but 

 lately been introduced, and on account of the great 

 expense, the method described is used by only a very

 said in favor of irrigation; and the use of windmills 

 and steam-pumps is becoming more general. Their 

 use will no doubt further increase as people learn more
