trol the scale which can positively be done so as to con- 

 tinue the life of the orchard and the production of profit- 

 able crops. The average annual cost per tree for treat- 

 ment depends mainly upon its size and ranges, for peach 

 trees, from one-half cent to three cents, averaging be- 

 tween one and two cents. The man who will allow his 

 total investment in trees, land and labor through three 

 or four years to be absolutely destroyed for lack of an 

 additional expense of a cent or two per tree each year, 

 cannot be considered as conducting his work upon any- 

 thing like business principles. 



Best Method of Treatment. — The fight against the 

 San Jose scale has developed several methods of treat- 

 ment which are of positive value. Three points require 

 consideration in determining which of these methods is 

 best and should therefore be used. 1. Safety. 2. Ef- 

 ficiency. 3. Economy. The method which has been 

 shown to best fulfill these conditions is "A WINTER 

 SPRAYING WITH LIME-SULFUR WASH." In spite 

 of numerous eflforts to replace this Lime-Sulfur with some 

 other material more easily prepared or less objectionable 

 to handle in application, the fact remains that this is 

 conceded by the great majority of orchardists, as well 

 as by entomologists, to be the best treatment yet found. 



It may be applied with safety at any time while the 

 trees are in a dormant condition. A single thorough 

 spraying with a properly prepared wash insures the con- 

 trol, if not the extermination, of the scale and is safer 

 and more reliable than is any other treatment. The 

 cost of treatment, varying in localities and with numbe>' 

 of trees to be treated, need not exceed from one to thii\, 

 cents per tree according to their kind and size 



Season for Making the Application. — The safest 

 and most effective time for treating trees for scale is dur- 

 ing the dormant period, that is, between the time the 

 leaves drop in the fall and the time the buds start in the 

 spring. Experimental work has shown that a single 

 treatment with Lime-Sulfur made in November or De-
