607. Relative composition of cane in the Louisiana 

 sugar-belt and in the coastal pine-belt. — Sugar-cane 

 grown on the sandy uplands of the coastal pine-belt is 

 ordinarily richer in total sugars than cane grown on the 

 alluvial lands in Louisiana. This difference is due prin- 

 cipally to the shorter growing season in the upland pine- 

 belt which increases the percentage of glucose, or non- 

 crystalUzable sugar in the canes. The percentage of sucrose 

 • in the cane is about equal in the two regions. 



As the greater part of the cane crop grown in the coastal 

 pine-belt is utilized for making sirup, the high glucose 

 content is a decided advantage as it decreases the tendency 

 of the sirup to turn to sugar. The cane crop of this regiop 

 is not especially suitable for making sugar as the glucose 

 will not crystallize and its presence prevents some of the 

 sucrose from crystalKzing.
