successive sprayings, should be four, three, and two pounds of copper 

 sulphate, with lime in proportion, These will be as effectual as though 

 the strongest solution were used continuously, while the expense is 

 decreased and the work is more easily done. 



Mr. C. F, Hale: Have there not been several different formulae given 

 out at different times? And is there any danger of getting it too strong? 



Prof. Taft: No; none of them are too strong, but weaker ones are as 

 well later in the season. I would advise two sprayings before the leaves 

 appear, and, on the peach, two after the petals drop. One of these spray- 

 ings may be done in the fall or very early spring. I would spray twice 

 yet this season, or oftener if rains are excessive. The spraying must be 

 done before the rpt of the fruit appears, and so as to all other fungi, for it 

 is a preventive to germination of the spores, not a cure after the spores 

 have grown and entered the leaves or fruit and are beyond the reach of 

 any remedy. 



Mr. MoERiLL: I find that in four or five cases, here, men have sprayed 

 peach trees with Bordeaux mixture, and the effect, in decrease of curl-leaf, 

 is plain to be seen. 



Prof. Taft : The spray will not stop the curl in any one leaf, but will 

 prevent spread of the fungus to others. 



Someone asked Prof. Bailey what nozzle he preferred, and he said the 

 McGowen, made at Forest Home, N. Y., and he went on to say: You have 

 no idea of the extent and thoroughness with which spraying is carried on 

 in New York, where it is the sole reliance for crops of fruit of all kinds. 

 Spraying is done four, five, six, even ten times per season. Its value is 

 various, and is not confined to the crop of the first year, but helps pre- 

 serve that of the next, by the increased vigor it gives the trees. He cited 

 the case of an extensive grape-grower in the Cayuga lake region, who 

 declared that if rot attacked his grapes he would cut them out, for he 

 could have no margin of profit if the annual expenses were in any way 

 increased. But Mr. Bailey told him he would find himself spraying, and 

 he did; and found also that he was making more money than before, so 

 much was the crop increased. 



Mr. Morrill: I have seen enough damage done by curl-leaf this 

 morning to pay for spraying all the orchards within five miles. 



Prof. Taft: Use of Paris green in the Bordeaux mixture will not hurt 

 any sort of foliage before the first of July, and it pays to do so; but the 

 arsenic should not be used within four weeks of picking. 



Mr. A. Adams of Shelby: A peculiar spot was noticed on some of my 

 peaches last year. At first it was creamy white, turning to reddish brown, 

 like freckles, and growing to the size of a dime. It did not seem to affect
