to be overflowed during the rainy season, such as the Ben- 
galees about Calcutta call Danga. It is often planted on 
land where sugar-cane grew the preceding year, and is 
deemed a meliorating crop. The soil must be well ploughed 
and cleared of weeds, &c. It is then raised, in April and 
May, according as the rains begin to fall, into ridges, 9 or 
10 inches high, and 18 or 20 broad, with intervening 
trenches 9 or 10 inches broad. The C5littings or sets, viz. 
small portions of the fresh root, are planted on the tops of 
the ridges, at about 18 inches or 2 feet asunder. One acre 
requires about 900 such sets, and yields in December and 
January about 20001b. weight of the fresh root."
