will dispose of a large proportion of the winter spores of the various 

 fungi and some insects. I shall then spray all the trees, trellises 

 and vines, and the surface of the ground where the fire has not run, 

 with sulphate of copper, one pound to 100 gallons. This is before 

 the development of the foliage when this strength is not objection- 

 able. Just before the blossoms open I shall spray all the folinge 

 with the solution, one pound to 800 gallons, to which I shall add 

 Paris green, one pound to 200 gallons. The mode of operation is 

 this : A fifty-gallon kerosene barrel, standing upright on a stone-boat 

 is filled with water, to which is added one ounce of sulphate of copper 

 previously dissolved, and drawn to the place where used. A three- 

 gallon pail is filled from the barrel and a teaspoonful of Paris green 

 weighing just one-fourth of an ounce is added. This is kept in 

 suspension by stirring with the Hydros[)rayer, or otherwise, at each 

 filling. The latter is emptied of its contents upon the foliage with 

 the necessary force, and refilled and emptied until the tree is fully 

 covered. This spraying with both substances will be repeated as 

 soon as all or ueaily all the petals have fallen, and again at two 

 different limes, a week or more apart, making in all, four si)rayings 

 after foliation. Iq their relative importance I should place the 

 burning and the spraying before foliation at the front for fungi, and 

 the first spraying after blossoming for most insects, but for the best 

 results none of them should be omitted. The mouth of June is the 

 time for the appearance of the great bulk of both insects and fungi, 

 and one hour's work at that season is worth a whole day later on. 



TOMATO ROT. 



During the early part of the winter, some 50 specimens of " rot" 

 appeared in my forcing house, on tomatoes, nearly ready to ripen. 

 I at once sprayed by means of the cyclone nozzle with copper sul- 

 phate (blue vitriul) 1 lb. to 1000 gallons of water. This was 

 repeated in two days. There has been no increase of the disease 

 since the application, and the spots seemed to dry up and the fuugus 

 not to penetrate the texture of the fruit at maturity. 



[While this experiment is in no way conclusive, and further trial must be made to 

 establish its value, the fact that so dilute a solution of copper sulphate is destructive to 

 the spores of most fungi, and that even under glass it is not in any way injurious to the 

 foliage, may lead to its use for the destruction of all f nngi attacking the foliage and 

 possibly by saturating the soil, for those attacking the roots.]
