108 FLORIDA FRUITS ORANGES. 



This is effectual for small trees but not so good on large, 

 because the upper limbs are apt to escape. 



FOR THE MEALY BUG. 



The formula given as No. 3 is the safest to apply to the 

 bug, as the other washes seem to injure it very little if 

 any ; kerosene will destroy it.
