Compared with other districts, the Hog Eiver valley produces mucli 

 more sugar per hectare of land planted, although three-fourths of this 

 comes from ratoon cane, and the limit of production has by no means 

 been approached. Somewhat less than the average amount of land 

 is here owned by each planter, but he has a much larger proportion 

 of what he owns under cultivation and produces annually over twice 

 as much sugar as the average gi'ower throughout the island. Apparently, 

 only a small percentage of the total land fit for sugar production in this 

 district is unused, but in reality about twice as much as is now con- 

 sidered suitable for cane growing could, by means of an efficient system 

 of subsoil drainage for the heavy ^T^ankil" soils and rice lands, be 

 brought into use.

■ Hacienda San Isidro. Same 



field as number 29, but 



closer to the Hog River 



and soil much sandier 



("tierra bombon"). 



! Yields larger with plant

I yield more than three 



I years of ratoons unless 



much water; now in first

nearly all fine yellow sand. 



/Hacienda Maria. "Tierra 

 mestiza," a mixture of 

 "bankil" and "bombon." 

 Best land said to yield 120 

 piculs (7. 6 metric tons) 

 sugar per hectare. Sur- 

 face soil is a clay loam; 

 subsoil beginning at 25 to 

 30 centimeters, a very 

 sandy loam, nearly pure 

 sand in parts, down to 50 

 to 60 centimeters, where a 

 layer of clay is again 

 encountered. This soil is 

 flooded by the Hog River 



V nearly every year.
