In the system of crop rotation prevailing in the government of Tula, 

 clover usually occupies a given field for two years ; one part of the 

 crop being used for hay and the other for seed. The fields are only 

 harrowed in the spring and afterwards remain without further culti- 

 vation. Favourable conditions are thus created for the hibernation 

 of beetles. The mixed cultivation of clover for hay and seed allows the 

 insects, after the removal of the hay harvest, to concentrate and breed 

 on the remaining plants. Clover for hay should therefore be kept 

 separate from seed-clover, the fields of the latter being as far as possible 

 aw^ay from the former ; fields of seed-clover should be deeply har- 

 rowed in autumn, after the harvest. Protective strips of unmown 

 clover should be left round the hay-clover fields, on which the insects 

 may oviposit and which can be afterwards cut for forage.

In view of the similarity of the conditions obtaining in the four 

 governments mentioned the author recommends the co-ordination of 

 the control of pests in them. To effect this, three or four observation 

 posts should be established in each of the four governments, the work 

 of which should proceed on identical lines, so that comparable results 

 may be obtained ; yearly conferences of the entomologists concerned 

 should be held and a periodical publication on the pests of the whole 

 region issued. The conference approved of these suggestions and it 

 was also resolved to apply to the Department of Agriculture for a grant 

 of £60 for the publication in question. In this connection the following 

 paper was discussed.
