No. 8 — Hellebore Speay — Far Pear and Cherry Slugs, Gooseberry and Currant Worms; 

 ingredients : — 



Hellebore 1 oz. 



AVater 1 gal. 



_,. ^. Steep the hellebore for an hour in one pint boiling water, then add the b'al- 



ance af water cold. To be used with spray pump. 



Note. — Hellebore may be applied as a powder, dusted on the trees or plants treated. A 

 machine known as Leggett's Powder Gun is a very efficient means for its use on a large scale. 

 In all cases, care should be taken to obtain good fresh hellebore, to ensure the results aimed at. 



No. 9 — Paris Green Spray — For Codlin Moth, Caterpillars, and other Jeaf-eating 

 insects ; ingredients : — 



Paris Green ; 4 ozs. 



Fresh slacked lime. .... . 1 lb. ' 



Water • 50 gals. ' 



Make a paste of the Paris green with a little water. Make the lime into milk of lime 

 of water, mix both these together, and add water to 50 gallons altogether. Paris green is a 

 heavy pOwder, and will not remain long in suspension, hence it must be kept 

 Directions. constantly stirred when using. Be sure that good fresh lime is used to pre- 

 vent the burning of foliage. Apply with spray-pump. London purple may 

 be used iii place of Paris green, but is not usually so reliable. 



Paris green can generally be used to advantage with Bordeaux mixture, making a com- 

 bined fungicide and insecticide, in the proportions given above, viz. : — 4 ozs. Paris green to 50 

 gallons Bordeaux mixture. Apply with spray-puinp. 



Spray No. 10 — Ammoniacal Copper Carbonate :— This will not be used so freely as the 

 Bordeaux mixture, on account of its greater cost and the increased labour of preparing it ; 

 but for spraying late in the season, when there is risk of staining the fruit with Bordeaux' 

 mixture, it is the most useful agent which has yet been tried : — 



Copper carbonate .'. 5 ozs. 



Ammonia 2 quarts. 



Water 50 gallons. 



Dissolve the copper carbonate in the ammonia and dilute with wajer to 50 gallohs. The 

 concentrated solution should be poured into the water. Keep the ammonia in glass or stone 

 jar tightly corked. 



Home manufaolure of copper carbonate.— As the precipitated form of carbonate of copper 



is not always obtainable, the following directions are given for its preparation : 



In a vessel capable of holding two or three gallons, dissolve 1| lbs. of copper sulphate in 



4 pints hot water. In another vessel dissolve If B)s. sal soda (washing soda) in 4 pints hot 



water. When both are dissolved, pour the second solution into the first and 



How to use it. stir briskly. When effervescence ceases, fill the vessel with water and stir 



thoroughly. Allow this to stand b or 6 hours, when a precipate or sediment 



will have settled at the bottom. Now pour off the clear liquid without disturbin.^ this 



sediment, fill up the vessel again with water and stir as before, then allow this to "stand 



until the sediment has again settled, and then pour of the clear liquid carefully as before- 



the residue or sediment is carbonate of copper, and from the quantities given there should be 



formed 12 ounces weight. Instead of drying this (which is a slow process), add to it 4 quarts 



strong ammonia, stirring well, and then add water to bring the whole quantity up to 6 quarts 



ihis may be kept in an ordinary stone jar, but should be closely corked. 



Each quart will contain two ounces carbonate of copper, which when added to 20 gallons
