good quality.. When the Hme is slacked, add sufficient water to the 

 paste to bring the whole up to twenty-five gallons. When the 

 copper sulphate is entirely dissolved and the lime is cool, pour the 

 lime milk and the copper sulphate solution slowly together into a 

 barrel holding fifty gallons. The milk of lime- should be thoroughly 

 stirred before pouring." 



The method described insures good mixing, but to complete this 

 work the liquid should receive a final stirring for at least three 

 minutes with a broad wooden paddle. 



Now for what is this good? It is good for leaf blight and 

 scab on plums ; for scab, bitter rot, and powdery mildew on apples ; 

 and for scab, and leaf blight and cracking on pears ? 



Xext, how to apply. For one having a good deal of this kind of 

 work to do it would undoubtedly be best to buy a knapsack sprayer 

 or a good hand pump with a hose and sprayer on end, said pump 

 being such as can be placed in a pail of this mixture and the spray 

 thrown over the tree. Many such are advertised, but of all things 

 do not buy a cheap one, as you will be disappointed and disgusted, 

 and your money will be thrown away. I do not think you can get 

 a satisfactory one short of $4 to $6. If you have but a few low 

 trees, try a watering pot with as fine a nozzle as is possible to get, 

 and with a good step ladder you can easily drench the tree, the only 

 trouble being waste of material. 



If using a watering pot it should be of galvanized iron, or if tin 

 it should be painted that the copper sulphate may not eat it. 



When to apply. First, just as the buds are swelling and, then, 

 after the blossom or even during the time of blossom, but follow up 

 once every week, at least, until four to six applications have been 

 made. If wishing to combat the codling moth, then as soon as 

 blossoms fall add to the solution either Paris green or London pur- 

 ple at the rate of four ounces to fifty gallons of water. To do this 

 make a stifif paste by stirring in water and then add the paste by 

 stirring the whole carefully together. Let me add, always stir your 

 solution before taking out to spray, that in case of any settling you 

 may get all the ingredients thoroughly mixed. 



Last of all remember that half, done is entire waste of time and 

 money. The only way to make a success of it is to follow it up 

 thoroughly.
