An experiment, conducted in 1914, on a farm of the Teachers College 

 in Novomerkovsk, govt, of Ekaterinoslav, has proved that tomatoes 

 provide an excellent remedy against aphids. The author therefore 

 recommends planting tomatoes, preferably the early variety, 

 " Ficarozzi," w^hich does not require much tying up, close to cucumbers, 

 melons and watermelons. When late varieties are used, it is necessary 

 to tie up each bush, otherwise the cucumbers and melons may suffer 

 from the dense shade. The tomatoes were planted in a chess-board 

 pattern, and besides protecting the plantations, yielded a good crop. 

 A neighbouring plantation not protected in this way, suffered greatly 

 from aphids.

The author refers to a previous article in which he stated, that, if 

 ants be destroyed, plants can stand the winter without being covered. 

 He repeats this statement after experiments lasting three years, during 

 which, owing to careful control of the ants, roses, vines, peaches and 

 apricots successfully passed the winter without cover. Aphids have 

 nearly disappeared ; there is no canker or gummosis and the trees 

 yield yearly more fruit. He has come to the conclusion that ants 

 mainly dwell at a considerable depth in the soil, and that in some 

 orchards, only a small minority appear on the surface, the majority 

 remaining the whole year underground. Bone meal was successfully 

 used to keep down the ants. N. F. Kashtchenko has controlled ants 

 with a very weak extract of fresh cow-dung, with good results.

This circular from the Entomological Bureau of the Zemstvo of 

 Charkov advises farmers to be on their guard against a threatened 

 outbreak of Oria {Tapinostola) niuscidosa, the caterpillars of which 

 last year injured over 43,000 acres of crops in the district of Izjum. 

 Stubbles and w^eeds on plots not ploughed the previous year should 

 be burnt, or if the stubble be short, ploughed in ; boundary strips 

 should be mowed ; plots which were damaged the previous year and 

 on which no deep reploughing was carried out in autunm, should be sown 

 with maize, buckwheat, millet, potatoes, bachza plants, etc., instead
