246 Success with Small Fruits. 



also disturbs and brings to the surface the worms that have entered the 

 soil to undergo their transformation. From first to last, tonic treatment 

 supplements and renders more effective our direct efforts to destroy 

 diseases and enemies. 



Most earnestly would I urge caution in using all virulent poisons 

 like Paris green, London purple, hellebore, etc. 



Whenever it is possible to substitute a less poisonous substance, 

 do so by all means. Some good people regard tobacco as the bane 

 of banes ; but to many it does not cause the feeling of repugnance and 

 fear inspired by hellebore and more poisonous insecticides. Let all such 

 articles be kept under lock and key; and one person should have charge 

 of their use, and be held responsible for them. Moreover, any water- 

 ing-can used with Paris green and like substances should be marked 

 with the word Poison, in large letters. If insecticides are used in the 

 form of a powder, great care should be exercised to keep it from falling 

 on other vegetation or fruit that might be eaten by man or beast. I 

 have known of pigs and horses dying from eating herbage on which Paris 

 green had blown from a potato field. London purple, which, as a 

 cheaper and equally effective article, is taking the place of Paris green, 

 must be used with the same caution, since it is a compound of arsenic, 

 and equally poisonous. 



It is my wish and intention to experiment carefully with the various 

 means and methods of coping with the diseases and enemies of small 

 fruits, and to give this chapter frequent revisions.
