not regarded as great. Spraying may tend to check this moth in 

 nurseries or parks, but is impracticable in forests. The caterpillars ot 

 Cydia {GrapJwUtha) strobilella, L., live and feed in fir-cones, in which 

 they winter, pupating in the next spring. In the Baltic provinces, 

 jfir-cones are also attacked by Dioryctria abietella, Schiff.

Mandarin oranges in Caucasia suffer seriously from the attacks of 

 scale-insects, against which sprays of soap-kerosene emulsion and 

 tobacco extract should be used. The plants wdth dense heads, pre- 

 venting the free circulation of air and sun, are more infested than those 

 which are properly pruned.

This is a continuation of a series of articles on locusts by the same 

 author [see this Review, A, iii, p. 437] ; in this one he deals with the 

 details of the organisation of the campaign. Mechanical methods of 

 control, requiring a large number of labourers, are usually organised 

 by means of forced labour, the whole population of a certain district 

 being obliged to take part in it. Thus, in 1912 the population of the 

 provinces of Syr-Darya, Samarkand and Ferghana supplied over five 

 million working days in combating locusts. This method of com- 

 pulsion leads to very inefficient work, a disadvantage which disappears 

 with the introduction of the chemical method, which it is quite practic- 

 able to organise on the basis of paid labour. The author also advocates 

 the centrahsation of the campaign against locusts in the hands of the 

 Central Government, the closer connection between entomological 

 organisations in different localities, and the creation of special local 

 funds for this object.
