In the pine forests of the Dehesa de la Albufera extensive damage 

 has been caused by Cnelhocwnpa (Liparis) proc€ssio)iea and Dendrolimvs 

 {Bombyx) pini. Many trees were entirely defoliated and died rapidly, 

 especially in hot and moist areas. A considerable number of trees 

 were saved from destruction by active and well-organised measures. 

 The most effective were : — Removal and destruction of the nests : 

 hanging out white cloths at night covered with a sticky substance an< 1 

 strongly illuminated ; spraying the smaller trees with a solution 

 consisting of sodium arsenate, 10"5 to 12'2 oz., quick-lime, 2"2 lb., 

 water, 22 gals. : and lastly by banding the trees and destroying the 

 larvae which collect in front of the belts.

Though it has been maintained that Coccids, especially Saisselui, 

 (Lecanium) oleae, Bern, (olive scale), cause the sweetish exudation on 

 which the sooty fungus develops, observation in the field shows that 

 this is a morbid process independent of any parasite and therefore 

 exclusively biological. It is believed that the fungi and Coccids are 

 commensals, both living on the exudation of the host-plant, and that 

 they cause an increased production of this by their presence.

This bulletin deals with the use of the more concentrated solutions, 

 intended for winter application, of the lime-sulphur mixture made to 

 the formula of the station for citrus culture at Acireale [see this Review, 

 Ser. A, ii, p. 412]. It is pointed out that on account of their greater 

 concentration the same minute care in dilution is not necessary as in 

 the case of the weak summer solutions. If too weak, the latter are 

 inactive, while an excess of strength may seriously scorch the tender 

 vegetation. This latter danger is naturally absent in winter.

This bulletin describes the construction of two pumps specially 

 adapted for lime-sulphur and for the benzine-petroleum mixture used 

 against locusts.
