Our fruit growers in general, by the faithful observance of the 
details required for the proper preparation and application of 
known remedies, experience no especial difficulty in controlling the 
scale on small trees. In many localities, while there is a full appre- 
ciation of its destructive capacity and of the danger in neglecting 
suitable treatment of the trees, the scale is losing many of the ter-
