GROUND BEETLES.

Eeport,' pp. 99-108, and the proportion of the chemical to 

 amount of soil is also given. Of these careful and repeated 

 experiments the result was so far from encouraging that the 

 experimenter's view is given as follows on p. 107 :— " Therefore 

 the only thing I can recommend is carbolic acid ; . . . and 

 I am afraid carbolic acid, although the cheapest remedy I 

 have found, will be far too expensive for the Americans to use. 

 Thirty-three ounces to fifteen cubic feet is equal to 6000 lb. 

 to the acre, and would cost, for acid alone, about £15. Then, 

 to be effectual, it should be thoroughly mixed with the soil 

 with a fork : I am quite sure ploughing alone would not be 

 sufficient. ... I may add in using the carbolic acid I 

 always mixed it with about twenty times its bulk of water, 

 and then used a water-pot, with a fine rose, to sprinkle the 

 soil, thoroughly mixing the soil afterwards." 



I much regret that my correspondent declined to allow me 

 to give his name except to special observers of this disease, 

 but I may mention that he is one of our largest Tomato 

 growers, and the great losses (up to tons of the fruit destroyed 

 by the Eelworm) made it very important to him if it had been 

 possible to remedy the evil. In his case the evidence pointed 

 to the pest having been introduced on plants of Dracana from 

 the Continent of Europe.
