in thickness, do not grow very tall, do not fall easily, and are resistant to commoner cane 

 diseases. In contrast to these are the varieties indigenous in India, which are less than an inch 

 in thickness and have a thick tough rind and much fiber. Canes are divided into three classes : 

 Ukl, thin and fibrous, with sweet juice; Paunda, 1^ to 2 inches in diameter; Ganna, § to 1 

 inch in diameter, with less fiber and more juice than the Ukl canes, juice poor in quality, 

 less hardy and more liable to disease. Author gives description of the habits of growth of the 

 cane and points out that in some cases the shape of the joints has been useful in determining 

 the male parentage of unbagged seedlings. Experiments have shown a well-defined tendency 

 toward the more slender seedlings being slightly richer in juice than the thicker ones. —

 This perennial grass had its origin in Mexico. A botanical description is given. It is propa- 

 gated by cuttings and produces forage having a comparatively high protein content for a 

 grass, according to the analysis given. It is attacked by the rust Puccinia polysora, which 

 causes little damage when the crop is cut at six month intervals. — F. M. Blodgett.
