 against this pest compulsory under the supervision of a special 

 committee.

This is part of a paper on the present state of the question of con- 

 trolling pests by means of parasites, read on 29th March last at a 

 meeting of the Horticultural Section of the Agricultural Society of 

 Turkestan. On the strength of data mainly drawn from the endeavours 

 made in America to import parasites from other countries, the un- 

 favourable results obtained by this system are pointed out. The 

 author considers this method of control theoretically unsound, as it 

 disturbs the equiUbrium which obtains in nature only temporarily. 

 The method advocated by Portchinsky, consisting in the utiUsation 

 of polyphagous parasites, by destroying their principal host by every 

 possible means, and thus causing them to direct their energies to other 

 pests, as well as the method of Rossikov, of assisting the multiplication 

 of parasites by selecting and separating the infested hosts from the 

 healthy ones, and destroying the latter, but not the former, are also 

 regarded as ineffective. Instead of trying to "control the laws of 

 Nature," the author prefers concentration on chemical and agricultural 

 methods of control. The meeting did not entirely agree with the 

 author's views, and expressed the opinion that there is no reason why 

 the services of allies offered by Nature should not be utilised. AH 

 available methods should be employed in the control of pests.
