Mr. Frazer may be seen in his spraying unifoim on the elevated platform. The Forest growers find the elevated platform a great help in doing efficient spraying. During April a number of vineyards were visited and a few rows of grapes in each were sprayed with the copper sulphate solu- tion. Starting June 13th, just before the blossoms opened, we again made the round from Winona to Niagara and Stamford, a distance of over 50 miles, with the cart spramotor. Over 4,000 vines at eight dif- ferent points were sprayed. The standard Bordeaux mixture was used throughout for the grapes. Soda Bordeaux was applied at Mr. Robertson's farm in St. Catharines to a number of cherry and plum trees to control the rot which is developing seriously owing to the prevalent moist, sultry weather. This mixture is made up of 40 gallons water, 4 pounds copper sulphate, with enough caus- tic soda or lye (ranging from 18 to 24 ounces according to its strength) to make the whole sHghtly neutral. The soda re- places the lime, and these will not discolor the fruit.
