hatched, the moths emerge about this time, and begin to 

 develop and lay their eggs, so that the eggs are hatched 

 along about the last week in June. Spraying at that time 

 should be put on so as to cover the foliage, and with the 

 idea that it will kill the young worms. We have found by 

 simply giving that second spray, even without having giv- 

 en the first spraying, it will aid the foliage, and that we 

 could cut out seventy per cent of the injury, so that it is 

 nearly as effective. I would not recommend depending 

 on that second spraying. The first is by all means the 

 most important, but if for any reason you are unable to 

 give that first spraying, it would be well to apoly this 

 second spraying, and the mixture will stay on the trees, 

 so that you will secure a good deal of benefit by killing 

 out the second brood when they hatch. This picture 

 shows the mixture on the leaves. That foliage was 

 sprayed about the first of June, and the photographs were 

 taken early in September. 



As regards material for spraying I should certainly 

 advise arsenate of lead, using two to three pounds to the 

 barrel. If you will do your work thoroughly, two pounds 

 is enough. I usually recommend three. Thoroughness is 

 very much more important, and two pounds is plenty if 

 you use it thoroughly. Arsenate of lead can be used with 

 the Bordeaux mixture, and with lime and sulphur. There 

 is still some little doubt as to the advisability of mixing 

 arsenate of lead and lime and sulphur. We have discard- 

 ed our Bordeaux mixture because we had so much injury 

 to the apples so that lately we use the lime and sulphur. 



Now about the apparatus. As a general thing, I rec- 

 ommend the barrel pump of the general type shown here. 

 There are plenty of them downstairs, and for orchards 

 ranging from three to five hundred trees, one of these of the 

 horizontal type is the most satisfactory. You can cover the 

 trees more quickly and maintain a higher pressure. For
