Java; fruit diseases, caused by fruit rot (PJiytoplithora sp.) on Hevea fruit, 

 which is also found on cacao and bread fruit; seedling diseases, caused by gray 

 blight (Pcstalozzia gueplni), also found on tea, and leaf spot (Cercospora sp.) ; 

 leaf diseases, due to several species of fungi, none of very much importance. 



The dry rot of construction timber, P. Billiet (Assoc. Fran£. Avanc. Sci., 

 Gompt. Rend., 31 {1908), pp. 553-557). — A description is given of the destruc- 

 tion caused by Merulius lacrymans in lumber and construction timber, the 

 author claiming that the mycelium produces a considerable amount of liquid 

 and that this liquid acts as a ferment, dissolving the cellulose of the cell 

 walls, or, in more resistant wood, causing their swelling and finally their de- 

 struction. 



Dry rot in timber, W. Ransom (Surveyor, 38 (1910), No. 982, pp. 61f3, 6U). — 

 It is stated that in this disease, which appears to be on the increase, moderate 

 warmth, moisture, and want of ventilation are favorable conditions for the 

 development of the fungus (Merulius lacrymans), and that its attacks are 

 confined almost exclusively to wood felled in the sap. 



Thoroughly seasoned timber made from trees cut at the proper season, with 

 sufficient ventilation around the timbers used in the building, will usually 

 escape attacks of dry rot. The application of carbolic acid, creosote, car- 

 bolineum, etc., is also i-ecommended as a preventive.
