lime is worthless. Flowers of sulphur should be used, though 

 any finely ground sulphur will do. Salt is not an essential 

 ingredient in the solution, its office being mostly to make the 

 material stick to the trees, therefore the cheapest salt is as good 

 as any, providing it does not contain dirt that will cause the 

 pumps to clog. By adding the sulphur to the lime, then slak- 

 ing with hot water, the heat from the slaking lime helps to 

 dissolve and mix the sulphur with the lime and shortens the 

 time necessary for boiling. The salt may be added at any time 

 during the boiling process. 



What to spray — Trees that have been infested with the scale 

 until they have become crusted, as well as old, neglected trees 

 are not worth spraying. The best remedy for these trees is 

 the ax. All trees should be severely pruned and cut back before 

 spraying, as much labor and material are saved by so doing, 

 and much better work may be done. All loose bark should 

 be scraped from the trees with a hoe, as this bark is of no use 

 to the tree, and may protect the scale from the spraying solution. 



In spraying trees in an orchard do not stop with the trees 

 that are known to be infested. If one tree in an orchard has 

 scale, the others are almost sure to have more or less scale also, 

 although often much care is necessary to find them. It is better 

 to spray a few trees which do not have scale, than to take the 

 chances of leaving trees that are infested. 



Questions and Discussion. 



Prof. Britton : Did it stick as well where you boiled it a 

 long time? 



Mr. Bennett : We found no difference. In some cases we 

 sprayed all day and a drenching rain followed ; we couldn't 

 see the next day but there was as much stuff as when we put 

 it on. We had to use more lime than sulphur. If we got the 

 best lime and used flowers of sulphur, we could use less lime 

 than sulphur. 



Prof. W. J. Greene of Ohio : We have had remarkable results 

 in Ohio. Last year our peach crop was almost ruined by borers. 

 Where the lime and sulphur was used, it completely prevented 

 this : it saved the crop. And as a fungicide it is better than 

 Bordeaux mixture, we think, and as a combined fungicide and 

 insecticide it is almost perfect.
