These samples differ somewhat from those obtained in other locali- 

 ties, in that they contain more fiber and a juice somewhat more concen- 

 trated and richer in sugar. The purity of the juice and its percentage 

 of reducing sugar is about the same as in other districts. It is difficult 

 to account for the increase in fiber found here, as the same variety of 

 cane is grown in San Carlos as in other parts of Negi'os, except on 

 the theory that the droughts prevalent in this section of the island 

 during the past few years have caused a partial drying out of the cane; 

 this would also explain the greater density and sweetness of the juice. 



The first three samples examined have undoubtedly been thus affected, since 

 they have been so stunted in their growth by dry weather as to be only about 

 half the ordinary size. The large amount of alkalies and alkaline earths in 

 these soils may also have a tendency, when concentrated by drought, to check the 

 growth of the cane. Number 45 probably owes its high fiber in a large degree 

 to the length of time it lias been allowed to grow without replanting, ratoons of 

 many years' standing apparently showing a tendency toward a harder, more
