being afterwards destroyed with kerosene ; traps of leaves of cabbage- 

 beets or sowthistles (Sonchus), underneath which the caterpillars 

 hide during the daytime ; hand collection of the caterpillars ; protection 

 of rooks, which destroy them ; the use of poisoned bran baits, as 

 recommended by Kurdjumov, consisting of 1 lb. of Paris green or 

 white arsenic to 25 lb. of bran, mixed with one gallon of water to which 

 two quarts of molasses have been added. The bait must be put into 

 the fields late in the evening so as to prevent it from getting dry before 

 the caterpillars begin feeding ; about one tablespoonful of the bait 

 at intervals of three feet apart is sufficient. Against the pupae, 

 cultivation between the beets in July and the re-ploughing in spring 

 of those parts of the winter fields which have been damaged in 

 autumn, are recommended.

The author calls attention to the enormous quantities of tobacco 

 dust which are obtained yearly in the tobacco industry and which 

 in most cases are treated as waste and destroyed. The high transport 

 rate of the Russian railways for this article is one of the reasons which 

 prevents the growth of its application in Agriculture as a manure and 

 as a very effective remedy against many pests. He refers to the work 

 of T. T. Kaike, who, in 1912, published the good results obtained by 

 fumigation with tobacco dust against Psi/lla ynali in the orchards 

 of the government of Orel in 1910-1912. Tobacco dust can also be 

 used as a decoction for spraying, the effectiveness of which has been 

 demonstrated by Glasenapp [see this Review, Ser. A. i, pp. 370-371] 

 against Psijlla mali, Aphis potni, Cheimatobia brumata and other pests. 

 The author used tobacco dust with success against Eriocampa 

 adumbrata, which appeared in 1910 and 1911, in August, on the leaves 

 of young cherry trees. The tobacco was applied as dust because the 

 larvae of E. adumbrata are covered with slime which may protect them 

 from liquid insecticides. The necessity of facilitating the sale of 

 tobacco dust free of duty, for which purpose it may be rendered 

 useless to smokers by the addition of kerosene or naphtha, is strongly 

 urged.

In the spring of 1914 an outbreak of Hyponomeuta malinellus, 

 unparalleled for the last 20 years, occurred along the Volga and Kama, 

 and at the beginning of June the orchards on the banks of both these 

 rivers, from Perm and Nijui-Novgorod as far as Saratov, turned quite 

 yellow. In the orchards in Simbirsk it appeared that sprayings with
