autumn. All fallen fruit should be regularly gathered up and fed to pigs 

 or deeply buried in the earth. Where a few choice vines only are grown 

 it will be quite worth while to cut out all discolored berries as soon as 

 they are noticed and get rid of the worms before they have extended 

 their injuries to others. 



INSECTICIDES. 



The following instructions for the preparation of the various insecti- 

 cides referred to in these pages are those that on the whole have been 

 found the most effective, in practice. Experiences will no doubt diff »r 

 and some prefer a variation in the quantities prescribed, but as already 

 stated, a great deal depends upon the care which is exercised in the 

 preparation and the skill with which it is applied. In this, as in other 

 things, practice makes perfect, and a remedy should not be discarded 

 because it has not proved absolutely effective on its first application. 



A Bulletin recently prepared by Professor Harcourt and Mr. Fulmer 

 of the Ontario Agricultural College and published by the Department of 

 Agriculture, "Insecticides and Fungicides," Bulletin 154, should be pro- 

 cured and studied by every fruit-prower. 



Lime-Sulphur Wash!. 



This is made with 22 pounds of fresh lime, 18 pounds sulphur (flow- 

 ers), and 40 gallons of water: another formula is 20 pounds lime and 15 

 pounds sulphur. The sulphur should be made into a paste with warm 

 water and added to the lime, which is slaked in about 15 gallons of warm 

 water with continued stirring. The mixture is then boiled for an hour 

 and a half in a kettle, or better, in a barrel with live steam. It should 

 be made up to 40 gallons with hot water, strained into a spraying tank 

 and applied to the trees while hot. The quality of the lime is important ; 

 the Beachville and Port Colborne limes are very satisfactory, but those 

 from the neighborhood of Guelph contain too much magnesia to be ser- 

 viceable. 



There are other methods of making the wash which will be found 

 described in Bulletin 154. 



SPRAYING REMEDIES. 



Paris Green and Bordeaux Mixture. 



Four pounds of fresh lime, 4 pounds of bluestone, and 4 ounces of 

 Paris green, thoroughly mixed in 40 gallons of water. In all cases where 

 spraying with Paris green is recommended in the foregoing pages it is
