EXPERIMENT STATION BULLETINS. 319 



edy. For a few trees in gardens and with no conveniences for boiling 

 the mixtures, the kerosene and lime possibly furnishes the best as well 

 as the cheapest of the mixtures tried. If, however, one does not care 

 to bother with making the emulsion of kerosene and lime, the Kil-o- 

 Scale or Scalecide will give very good satisfaction, if the strength is in- 

 creased or if two applications are made. 



To determine some of the effects of the remedies recommended for 

 scale upon the different kinds of fruit trees when in full leaf, a number 

 or experiments were carried on. For this a single branch only was 

 taken and sprayed thoroughly with each of the following mixtures on 

 July 20th, with the folloAving results : 



Lime, sulphur and salt of the usual strength: 



Peach, the foliage was burned quite badly and manv of the leaves 

 fell off. 



Pear; much injury to the leaves, but they did not fall off. 



Sour cherry; foliage seriously injured and some of the leaves dropped.
