(Chilo simplex) has already made burrows for its offspring. 

 But the rind fungus will be noticed in canes altogether free 

 from injury caused by the borer or other insects. Perhaps 

 the practice of tearing and breaking off of leaves at the time 

 of tying and trashing, also helps in the lodging of the spores 

 of the fungus in the rind. 



1,384. Experience on the Sibpur Farm has shown us 

 that superior varieties, such as the Chittagong f{ Patna Ku- 

 sur" and the Samsara, are far more subject to the attack of 

 this fungus than poorer varieties such as the Khari sugar-cane. 

 It has been also seen that if tops are used for seed and if 

 these are dipped in a solution (i : 200 or 300) of sulphate of 

 copper at the time of planting, the disease can be arrested. 

 The old affected fields must be set fire to as also the dry 

 leaves and trash accumulating at the time of harvesting and 

 crushing of canes. Rotation should be invariably practised 

 in cultivating sugar cane as the same field if it is used for 

 growing sugar-cane year after year must become a hot-bed 

 both for the condia of this fungus and for the grubs of the 

 borer moth. Growing of canes from seed and then gradually 

 establishing a healthy stock has been found beneficial in Java 

 and other cane-growing localities where European planters 

 are employed in the cultivation of cane. But the result 

 from seedlings is always very uncertain. 



CHAPTER CXXXI. 



MUSHROOMS (AGARICUS COMP^STRIS). 



TT must not he supposed that all fungi are noxious pests. 



Some of the mushrooms (which are one of the highest 



fungi) offer very palatable food, and if the food can be 



digested, it is very nutritious. Some mushrooms are very
