surface of the leaves and branches as well as would either ingredient alone; it seemed 

 to gather in small drops on the tree. Therefore, for the reasons that the combination 

 is hard to make and cannot be so effectively applied as could be either ingredient 

 alone, I cannot recommend the Cornell mixture to fruitgrowers. There are also, on 

 the whole, but few instances where we need to spray for the sucking insects at the 

 same time as for the chewing insects and fungi. The kerosene emulsion also cannot 

 be mixed with the arsenites alone. 



SPOTTING OF QUINCES. 



Mr. WiLLAKD said Mr. Hopkins had spoken to him in reference to his large planting 

 of Orange quinces beginning to spot. The speaker said Mr. Maxwell came to look over 

 a few quinces he had, and finding them clean, and free from funj^i, asked how he cared 

 for them. His reply was that he gave them no care; he cut off about one-half the 

 previous year's growth, and the only thing furnished in the way of plant food was 

 wood ashes. Some years before, when Mr. Willard gave them rich, barn-yard manure 

 they did spot; but they stopped it, and he believed that was the trouble with others. 

 Mr. Hopkins told him his plan of cultivation. Mr. Willard does not plow deep, but 

 vises the Rochester gang plow, and cultivates entirely with the spring-tooth harrow. 

 Mr. Hopkins had some quinces that were not dieturbed during the summer, and they 

 have not been inclined to spot. The proper plant food had more to do with this disease 

 than anything else. Mr. Willard believed fruitgrowers had been using too much 

 nitrogenous substances and too little potash; and they would have to do lees spraying. 



Mr. WooDARD had a little tool made specially for him to cultivate his orchards of 

 peaches, quinces, etc. It was a cut way harrow. Instead of putting the sections close 

 together, he had it made so he could work the heads and arrange it so he could 

 cultivate close to trees. He had three of these tools, and would not sell them for a 

 hundred dollars apiece if he could not procure others of the same make.
