PLANTING AND CULTIVATING. 



When the crop is intended for snaps, make the rows 

 two and a half feet apart, and thin the plants to four 

 or six inches apart in the row. Make the row as 

 straight as possible; this will save labor in cultivating. 



In sections where artesian wells may be employed to 

 irrigate, the rows should be run on contours. When 

 such contours lines have been established, they will 

 serve as guides by which the irrigating system is laid 

 out. A very simple and effective method has been 

 employed with good success by some vegetable growers 

 in South Florida. The field, after the contour lines 

 have been located, is thrown up in beds wide enough 

 to hold but two rows. These beds are made by using 

 a large two horse plow and throwing up a head-land 

 for every two rows of the crop to be planted. This 

 leaves a double open furrow for every two rows. 

 When the water is turned into such an open furrow, 

 it moistens the land quite thoroughly. Such work 

 requires a great amount of water, and is not practica-
