SPRAYING THE APPLE ORCHARD. 



How to Apply the Spray. — The spray should be applied 

 from four sides of each tree as it is impossible to cover 

 all parts of the tree from two points. In orchard 

 work, drive to the interval between four trees and 

 spray one fourth of each, proceed to the next in- 

 terval and repeat the operation and so on. Then, by 

 coming back on the next row, the other side of one row is 

 sprayed and each tree has been sprayed from four sides. 



The first two sprayings 

 before the trees bloom 

 are principally against 

 the diseases, and for 

 them a nozzle should be 

 used which will throw 

 the finest possible 

 spray and evenly cover 

 the foliage with a thin 

 film. The finer the 

 spray, the less jnixture 

 is used and the better 

 the foliage is coated. 

 The spraying just af- 

 ter the petals fall is 

 the principle one 

 against the apple worm 

 and must be directed 

 from above the fruit 

 with considerable 

 force, so that the spray will be driven into the open calyxes. 

 A nozzle giving a strong spray, leaving the nozzle in a good 

 stream and making a spray with more force, is therefore 

 desirable. Nozzles attached to the extension rod so as to 

 form an angle of 30 or 40 degrees to the rod, will be found 

 serviceable for this spraying. For the last two sprayings, 

 a fine mist, as for the first two, is desirable. Do not try to 

 spray against a strong wind. Spray from the windward
