is said to degenerate, or become poor, in long culti- 

 vation ; but this is probably due to bad treatment. 



2. Otaheite Ribbon cane, or Striped Tanna : This 

 also is a rich cane, but the sugar is not always perfectly 

 white. The internodes are yellowish, with bluish or 

 purple stripes. This and the preceding variety are the 

 most popular varieties in almost all countries. 



3. Java Transparent: This is a quick-growing cane, 

 with internodes 10 to 20 cm long, which bear blood-red 

 stripes. It is an excellent variety for light ground. 

 Selangore is a similar or identical cane, common in 

 Malaya. 



4. Black Java : This has purplish or black inter- 

 nodes 8 to 1 5 cm long ; or, toward the top, it may be 

 striped. It endures bad treatment better than other 

 canes, and produces a sweet sap. But the sap is not 

 abundant, and the cane is too hard to mill very well. 



5. Elephant cane : There are several canes with this 

 name, of which the Cochin China Elephant cane is the 

 largest and best known. This wants a rich soil, and is 

 too brittle to mill well.
