3 fluid ozs. of water in an earthenware vessel beneath the tent. The gas is very 

 light and rises to the top of the tent, and if this be kept on the tree for half an 

 hour, every scale will be destroyed. The quantity of ingredients given above is 

 suflficient for a tent enclosing 150 cubic feet. 



What is wanted, however, is to know the best remedy, and it is satisfactory 

 to learn that on the whole the standard remedy for scale insects, kerosene emul- 

 sion, is the best. In summing up his experience of the year, Mr. Howard says 

 as follows ; " Remedial work against this insect is onerous, but our experience 

 has shown that three sprayings at intervals of ten days during the latter part of 

 May and June, will practically destroy the insect, whether the spraying be 

 conducted with very considerably diluted kerosene emulsion or with a resin 

 wash, while during the winter a single application of either of the three winter 

 washes will greatly reduce the numbers of the insect. Among the winter washes 

 our experience leads us to give the preference to strong kerosene emulsion ; 

 next to the winter resin wash ; and finally, to the lime, salt, and sulphur mixture. 



The kerosene emulsion is now well-known to most Canadian fruit growers ; 

 but it may be well to give it here : 



Kerosene (coal oil) 2 gallons. 



Common soap or whale oil soap ., . \ pound. 



Water 1 gallon. 



Cut up the soap and boil the water till all is dissolved, then add it boiling 

 hot to the coal oil ; churn the whole briokly for five minutes with a syringe or 

 force pump. When the emulsion is perfect, it will adhere without oiliness to 

 the surface of glass, and when cooling forms a jelly-like mass, which can be kept 

 indefinitely if stored in a cool place and covered from dust. 



When required for use, for a summer wash, dilute one part of the stock 

 made as above with nine or fifteen parts of water. To make the stock dissolve 

 easily, take first three parts of hot water to one of the emulsion, and then, when 

 all is thoroughly mixed, add sufficient cold water to make the nine or fifteen parts 

 required ; for a winter wash mix with four and a half or nine parts of water. —

The New Horticultural Society at Woodstock promises to be a very 

 large and successful organization. On the evening of the 23rd of January, Mr. 

 Thos. Beall and the Secretary addressed a special meeting of citizens called 

 together by the President of the Board of Trade, Mr. D. W. Karn. The work 

 of our Association was clearly presented, showing the various departments of 

 work we have in hand : as Spraying, Experiments, Prevention of Fraudulent 

 Fruit Packing, Study of Fertilization of Flowers, of Fungi and Insects, etc. 

 Then Mr. Beall placed before them the best method of conducting a Horticul- 

 tural Society, in order to give the most good to the largest number ; after which 

 it was decided to form a Society at once.
