40 INTENSIVE FARMING 



visions for sub-irrigation this system of culti- 

 vation can be made highly profitable. 



Considering the fact that such a great num- 

 ber of plants can be grown by the "New Cul- 

 ture System " and that a system of double 

 cropping will permit growing both an early and 

 a late crop on the soil during the same season, 

 the crop is especially attractive from the grow- 

 ers point of view. 



To grow the early and late crop on the same 

 area it is necessary to plant two sorts in al- 

 ternate rows three feet apart. By using Golden 

 Self-blanching or White Plume for the early 

 crop and Giant Pascal or Boston Market for 

 the late, the alternate rows of the early sort can 

 be blanched with boards or paper as soon as 

 large enough and by marketing it immediately 

 the ground can be cleared in time to make the 

 earth between the six foot rows in which the 

 late sort stands available for blanching it as 

 much as is desirable before placing it in storage. 



Few other vegetable crops lend themselves 

 to culture under such extremes of latitude, to 

 both early and late planting, to long distance 

 shipment, and to winter storage as does celery.
