covering of vegetable surface soil with a subsoil of extremely fine yellow 

 sand and silt. Cane planted here grows superlatively well in years of 

 plentiful rainfall, but is apt to yield a rather watery, impure juice, 

 and does not stand drought well. With a little irrigation to tide them 

 over dry spells, such lands should produce much better than they do 

 at present. 



Adjoining the "bombon" soil and at a somewhat lower level and a 

 few hundred meters from the river is the so-called "tierra mestiza,'' 

 a black loam, which, as its name indicates, is a "mixture" of very fine 

 sand and silt, with a little clay. The subsoil is likewise very fine 

 sand, silt, and black clay, sometimes well mixed, sometimes in streaks. 

 This is considered the best land for cane growing, as it produces large 

 cane of good quality, has good natural drainage, and yet is not injured 

 by a moderate amount of diy weather. 



Farther away, in lower land, where the floods stand at times long- 

 enough to deposit the iinest silt and clay which they carry, are the 

 %ankil" or heavy clay soils,^ which are stated to yield the richest 

 cane, although not as heaAy in tonnage as the others. In dry years 

 these lands are reliable producers, but early, excessive rains coming 

 before the young cane has attained a sufficient height often have a 

 very hamiful effect, imless the land is divided into small fields by 

 ditches and artificially drained at considerable expense. The heaviest 

 of these "bankil" soils are not much used at present for cane growing 

 because of the difficulty of working tliem, and are either left uncul- 

 tivated or used as rice lands.
