On the effect of soil treatment for the prevention of insect 

 injuries, J. Ritzema-Bos (Zischr. PflanzenkranTc., 8 (1898), JSTo. 2, 

 pp. 113-121). — The author reports on the use of benzin and carbon 

 bisulphid injected into the soil for the prevention of injuries caused by 

 nematodes and various root eating insects. The form of injector is 

 described and notes are given from correspondence with quite a num- 

 ber of individuals relative to the use of the same. It is shown that by 

 the injection of benzin and carbon bisulphid into the soil all the injuri- 

 ous insects are destroyed for a considerable distance. An experiment 

 is reported in which carbon bisulphid was injected into the soil of an 

 oat plat, with the result that there was a very material increase both 

 in straw and grain. It is said that oats could not be grown in this soil 

 heretofore on account of the serious attacks of nematodes.
