calm or when the wind is blowing from the opposite di- 

 rection to that during the first spraying. The spray so- 

 lution must be continually agitated during the spraying 

 and a properly constructed pump will accomplish this. 



The disagreeable effects of getting the wash on the skin 

 may be reduced by rubbing the hands and face with vas- 

 eline before spraying. Rubber coats and gloves are, of 

 course, the best protection for the sprayers but if not 

 available old clothes should be worn so that they may be 

 discarded after the work is finished. Cheap canvas work 

 gloves are a satisfactory protection for the hands. The 

 mules, or horses, and the harness may well be protected 

 by blankets made of old burlap sacks. 



After the days work is over the remaining solution 

 should be drawn or emptied out and clear water run 

 through the pump, hose and nozzles to leave them in clean 

 condition and reduce the corrosive injury to the outfit 

 which would otherwise be as great through a night of 

 standing as through a day of use. This cleaning should 

 be particularly thorough at the end of each seasons work 

 or when the apparatus is to be stored for any length of 

 time. All working parts should be kept thoroughly oiled. 

 These measures of care will reduce the expenses for re- 

 pairs and improve the ease and quality of the work done.

 of the many advantages of this wash. It adheres to the 

 trees for a long time and its good effects are continued 

 through several months after the application. It acts 

 both as an insecticide and also as a fungicide. 



As an insecticide it is effective for nearly all of the 

 scale insects oscurring upon fruit trees. It destroys the 

 winter eggs of the plant lice which attack the leaves 

 and twigs of apple so abundantly in the Spring. It also 

 controls the "pear-tree Psylla" and the "pear-leaf blister 

 mite" as well as the , 'silvering mite" of the peach and the 

 "peach-twig borer." 



At the same time as a fungicide it is exceedingly effec-
