The preventive treatment of borers is best accomplished by coating 

 the trunks of the trees with some application which deters the adult 

 insect from depositing its eggs thereon. 



The worming of trees is also referred to, but spraying is particularly 

 recommonded. The writer advocates as many as five sprayings with 

 copper sulphate, Bordeaux and arsenite, and gives full directions as to 

 same. — V. J. M.

 styles and stigmas, length of external and internal pedicels, average 

 number of flowers in an inflorescence, average diameter of flower,
