can omit tlie midsummer spraying (ISTo. 5). The treatment that comes 

 three or four weeks after the blossoms fall (ISTo. 4) can be omitted if 

 necessary. This leaves only one more, namely, the one just after the 

 blossoms fall (JSTo. 3), and this is the one most important treatment for 

 every bearing apple orchard, for every such orchard is infested with Cod- 

 ling Moth, Curculio, and leaf-eating insects, and we simply must give 

 this treatment after the blossoms fall, if we are to have a full crop of 

 perfect fruit. Here is a statement of what we consider the relative im- 

 portance of the five treatments : 



First in importance — No. 1. Winter treatment, if there is scale. 



Second in importance — ISTo. 3. Just after blossoms fall. 



Third in importance — No. 5. Summer spraying, if fruit rots on tree. 



Fourth in importance — No. 4. Three to four weeks after blossoms fall. 



Fifth in importance — No. 2. Just before flower-buds open. 



So it depends upon what your troubles are as to which of the treat- 

 ments you can afford to miss. If you have no scale, but have trouble 

 with fruit rotting on the trees, then you must give the summer treatment, 

 while you may leave out the winter one. But if you have scale and do 

 not have trouble with the rots, then you must give the winter treatment 

 and may omit the summer one. If you have both scale and rot, then you 

 must give both the winter treatment and the summer treatment. But 

 every bearing orchard has Codling Moth, Curculio, and leaf-eating in- 

 sects which are reached by the treatment just after the blossoms fall 

 (No. 3), so that stands out preeminent as the one treatment that every 

 bearing orchard should receive. 



Experience is the only teacher that can show to each and every grower, 

 just what precise treatments he should use. One man will adopt a regu- 

 lar system of three treatments, another two, another four, and another 

 five. But it is only the grower who studies for himself, and who knows 

 just what the most important enemies in his own orchard are, who can 

 hope to get the best results. 



SPRAYING OF APPLES REDUCED TO SIMPLEST TERMS. 



There are a good many growers who would like to get good fruit and 

 would be willing to go to some expense to get it, but who simply will not 

 bother to change from one material to another, memorize a lot of formu- 

 las, and vary the strengths of the mixtures. These persons want to know 

 of some one spraying treatment which they can adopt with reasonable 

 success, and they are willing to take slightly poorer results if by so doing 

 they can bring the matter down to a basis of easy simplicity. 



For all such persons we recommend the Commercial Lime-sulphur at 

 1^2 gallons to 60 gallons water, with 3 pounds of Arsenate of Lead Paste.

If this material be used for all spraying treatments, winter and sum- 

 mer, it will come as near giving satisfaction as any one material. It is
