the oyster-shell scale, but underneath the minute crust 

 you may find small purplish-colored eggs. 



Cottony maple scale attacks not only maples but nxuner- 

 ous other ornamental trees. In early spring or simimer it 

 resembles small tufts of cotton at the outer ends of the 

 branches. It winters over as an inconspicuous brown scale 

 on the rough bark of larger limbs and branches. 



Rose scale resembles the scurfy scale, but is lighter in 

 color and attacks roses and cane fruits. 



The saw fly has greenish, spiny larvae that feed upon 

 the leaves of the cane fruits. It is susceptible to winter 

 spraying. 



Winter Sprays and Spraying 



The two specifics for winter spra5dng are lime-sulphur 

 wash and miscible oil preparations. For use in the small or- 

 chard it is generally more convenient to buy sprays ready 

 to dilute with water than to attempt to mix them at home. 

 If you are not famihar with the different brands it will be a 

 good plan to write to your experiment station for advice. 



If you prefer to make your own lime-sulphur boil for an 

 hour in an iron kettle four pounds of lump lime, three 

 pounds of flowers of sulphur and five gallons of water, 

 adding five gallons more water when ready to spray. 

 Spraying is done preferably before the mixture has entirely 

 cooled. A " self -boiled " mixture may be made by using 

 lump lime, flowers of sulphur and water in the proportion 

 of eight each of lime and sulphur and fifty gallons of water. 

 Slake the Ume in a little warm water, and when it is slaking 

 freely sift in the sulphur and stir thoroughly until a thick 

 paste results. Keep it covered until it is through "boiling" 

 and then cool down with the remainder of the water, and 

 use as soon as possible. 



Success in sprajang — with a reliable mixture — depends 

 entirely upon the thoroughness of the job. Every square 

 inch of surface and each crack and crevice must be entirely
