Dapug.—This method is described as used in Rizal and Bula- 
can Provinces. A framework of bamboo is placed on mud and is 
covered with a mat of banana leaves woven together. The seed, 
usually germinated previously, is sown very thickly on a thin 
layer (about 5 centimeters) of decomposed organic matter cut 
into fine pieces. Due to the abundant moisture furnished from 
below, growth readily takes place. Within from twelve to fifteen 
days the seedlings are either rolled up and placed on a well- 
prepared seed bed or are transplanted into the field.
