is raised on low delta- or alluvial lands that will permit of 

 inundation. In lowland rice culture, flooding of the field 

 is usually resorted to in order to hasten germination; after 

 the plants have attained a height of several 'inches, from 

 3 to 6 inches of water are turned on to the field and kept 

 there continuously for twenty, thirty, or more, days, de- 

 pending upon the region. The water is renewed occasionally 

 to prevent it from becoming stagnant. It is drained off 

 just prior to the ripening of the grain.
