crop, as in the case of the starUng, which damages vines far more than 

 it protects them from insects, but is beneficial in fields and woods, though 

 not in the vineyard.

It is stated that Scolytids do great damage to spruce trees in 

 Manchuria and that the increase of these beetles is favoured by the 

 fact that the forests are full of fallen trees.

This paper gives a fuller account of the author's use of poisoned baits, 

 against grasshoppers [see this Review, Series A, v, pp. 196]. In some 

 experiments with balls of bran, moistened in water and some aromatic 

 substance, it was found that Gomphocerus sibiricus and other northern 

 species are able to differentiate between odours. The smell of mint 

 added to the bait increases its attractiveness, while burdock-oil and 

 stale molasses decrease it. The odour of wet bran is itself very 

 attractive and the grasshoppers \vill devour it even after it has become 

 dry. The fact that this species does not collect in large swarms and 

 does not travel long distances, greatly favours the application of this 

 remedy.

This is a paper read at the first meeting of the Commission for the 

 control of pests and diseases of orchards in the province of Batum. 

 The report suggests limiting the operations of the Commission for the 

 present to the coastal regions of the Province, where there are some 

 900 orchards.
