It is stated that no insects have ever been observed by the author 

 in the Governments of Podolia, Cherson or Bessarabia to injure 

 Rhus cotinus, and it is thought that the odour of this plant, and the 

 tannin it contains, keeps them away. It is also free from the attacks 

 of fungi.

These two reports, for the second and third years respectively of the 

 existence of the Station, give a general account of the consulting and 

 teaching work of the staff. Practical classes on the control of pests 

 were held in May 1913 and in June 1914, the courses including lectures 

 on the chief pests and diseases of plants in the government, preparation 

 of insecticides and fungicides, and practical exercises and excursions ; 

 the cost of the classes in 1913 amounted to £20. Similar courses were 

 held at various places in the Government and travelling detachments 

 of instructors were also organised. The expenditure of the Station in 

 1931 amounted to £1,020 and in 1914 to £1,200, defrayed partly by 

 contributions from the Department of Agriculture, and partly by 

 the Zemstvo.

The adults of Anthonomus pomorum, even when hungry, rarely touch 

 the leaves of plums and pears, but the leaves of apples are devoured 

 from the under-surface. Spring spraying with milk of lime, mixed 

 with crude carbolic acid (2 lb. to 30 gallons of the milk), gave fairly 

 good results, but does not completely prevent oviposition. During five 

 years, experiments with straw belts showed that the most effective 

 type of belt is provided by ropes of straw twisted round the trunk in 

 such a way that the first and second bands are parallel a few inches from 

 each other, the third one covering both of these and forming a hoUow 

 space underneath it, in which the insects hide freely. The whole is 

 then covered with ordinary packing paper, acting as a waterproofing. 

 Such a belt can be smeared with adhesives and thus used in spring to 

 prevent various insects from reaching the crown of the tree. In
