On pp. 66 and 126-179 of the German edition there is a long 

 account of Sereh. He thinks this disease is due to bacterial 

 occupation of the vessels of the cane. The organisms resemble 

 Bad. tertno.

Twenty-four acres of cane-cuttings treated with copper sul- 

 phate for Sereh yielded 9 per cent more cane and 20 per cent 

 more sugar than 24 acres untreated.

Thinks Sereh due to plugging of vessels and that pushing of 

 adventive buds is due to the same cause. Says De Vries and 

 Wakker induced pushing of such buds in Bryophyllum caly- 

 cinum by reducing or wholly withholding water.

Describes Bacillus sacchari and B. glagae. Work very defect- 

 ive from the modern bacteriological standpoint. Janse found 

 his bacilli not only in sugar-cane, but in nearly every other 

 plant he examined and in healthy plants as well as diseased. 

 The organisms exist normally in sugar-cane and only cause 

 Sereh when peculiar unknown conditions arise.

This paper deals with the occurrence of bacterial slime in 

 closed cavities in the internodes of sugar-cane. Some joints of 

 otherwise normally developed cane were one-sided, often to a 

 very marked degree, so that there was great distortion, and this 

 phenomenon repeated itself in cane derived from the cuttings of 

 such plants. Just above the nodes in such malformed inter- 

 nodes, or at least somewhere in the vicinity of such nodes closed 

 cavities containing bacteria were found, and these bacteria 

 occupied the vascular bundles also, both above and below the 

 cavity, particularly in the node, so that sections therefrom much 

 resembled cane attacked by Sereh Studies, however, of very 

 early stages of these cavities led Valeton to think they appeared 

 prior to the presence of the bacteria and were due primarily to 

 some interior disturbance in growth rather than to bacterial 

 development. Ninety per cent of the plants derived from canes 

 received from Mr. Moquette were thus diseased, and of the 300 

 varieties cultivated by this planter 32 are said to have shown 

 this deformity with the internal cavities in more than half of 

 them. As I read Valeton's account, the signs of this disease 

 are quite unlike those of Cobb's disease, in that the cavities 

 occur in the distorted lower joints of the cane at a height 2 to 4 

 feet from the ground, the canes being otherwise normal in ap- 

 pearance. The size of these cavities varied from a pin's head 

 to a length of 4 cm.
