FIFTEENTH ANNUAL MEETING. 49 



on the peaches before tlie leaves come out, that is to cor.trol 

 as iiuich as we can the rot that is on the tree, and the leaf 

 •curl that is so injtirious in our peach orchards in Delaware, 

 and I presinne you also have it here. With our pear-trees, 

 ■we do not find we are oblip^ed to spray before the blossom ap- 

 pears, but the sprayings may be generally afterwards. With our 

 plums, the Japanese and the American, we find we have to 

 •spra\- Ijoth before and after to get good results. We cannot 

 spray the plums, all of them, with full strength bordeaux, but 

 with three pounds of sulphate of copper to fifty gallons of 

 water very little injury will be done, if that is carefully worked 

 out. In growing currants in Delaware, if we want to grow a 

 good crop, we find we have got to protect the leaves of the 

 currant with bordeaux. Take our nut trees, our chestnuts, 

 we can keep them in perfect foliage all through the season 

 until the wind whips them ofif in the fall by three sprayings of 

 bordeaux after the foliage is out. We have gone into nut 

 culture, some of us around there, and for filberts and English 

 walnuts they must have the bordeaux on the leaves to keep the 

 foliage. I want to impress upon you, if I have not, that no 

 tree can bear fruit the next year, and do the best it can, that 

 sheds its foliage anv time tmtil the fall frost or the da\' that 

 they should be shed. 



X"ow% as to spraying for the San Jose scale, something that 

 "bobs up in every agricultural society at their meetings. Wdiy, 

 three or four farmers cannot get together in any store without 

 it bobs up. \\'e have remedies, quite a good many of them, 

 and I can say that the sulphur mixture as usually used is a 

 preventive ; it will hold the scale in check ; that has been 

 clearly shown. An inspector in the state of Delaware told me 

 this fall that he knows orchards that were badly infected with 

 scale that were sprayed with such sulphur mixture, that are 

 not only holding their own, Init there is less scale th.an there 

 was a year ago. I have been told by the same inspector that 

 where crude petroleum was used the same conditions are to be 

 found. T have a ncighl)or who s])rayed with 150 test kerosene 

 who says the same thing, and from my knowdedge of his trees 

 T say that he says the truth. There are instances in Delaware 

 where the lime and kerosene have been used with the verv
