This is best prepared in quantities of 24 or more pounds at a time. Place 24 Ib. 

 of lime in a barrel, add enough cold water to keep the lime slaking well, and dust 

 24 Ib. of sulphur, which has been first worked through a screen to break the lumps, 

 over the lime; then add enough water to complete the slaking. Stir well with a hoe 

 to prevent the lime from cakirg on the bottom. As soon as the slaking is over, add 

 enough cold water to cool the whole mass and prevent further combination of the 

 lime and sulphur. Dilute" with enough water to make up the strength of the above 

 form u lie. Strain diluted mixture through sieve into spray-tank and agitate well 

 when using. 



Dry Sulphur is sometimes used as a fungicide to check the spread of mildews 

 and brown-rot on plums, cherries, etc. For this purix.se it is dusted on the tree, or 

 vine, when the disease is first noticed. It is doubtful whether this is practicable on 

 a large scale. 



Potiixftlmn SuJphide (liver of sulphur) is sometimes recommended for the control 

 of rnilde of the above to 10 gallons of water. It does not spot 



the foliage or fruit.

ammonia to dissolve it. Dilute with 40 gallons < f water. If the ammonia is very 

 strong it Me to dilute it with water before adding to the copper carbonate. 



Bordeaux Mixture. Where Bordeaux mixture is to be used in quantity it is 

 advisable to make stock solutions. To make a stock solution of copper sulphate, put 

 JO gallons of water in a 40-gallon barrel; place in sack (preferably of a coarse 

 nature, such as a light bra -> Ib. of copper sulphate (blueston*) ; suspend 



this in a barrel so that the bottom of th hes under water. In a 



few hours, or at least a few days, the copper sulphate will go into solution. Mark 

 on the inside of the barrel the surface of the solution, so that if any evaporation 

 takes place it can be repla.-ed with water to make up the original quantity. After 

 the copier sulphate is all dissolved each gallon of the solution will contain 4 Ib. of 

 copper sulphate. This projiortion is given as an example, hut any quantity can be 

 used to suit the requirements <:f the maker. Ii -irable to dissolve more than 



is required for a mouth's m will become weak through m-rystallization at 



the bottom of the barrel and requir n]y brass or wooden 



I as a container. 



Lime. Only good fresh stone-lime should be used. This can be made into a 

 urg the lime, use just enough water to make it slake 



rapidly without being which indicates burning through lack of 



water. Wat-h the lime carefully while slaking and keep it stirred. If the lime is 

 r.ot first quality, better results will be obtained through the use of hot water. If the 

 above directions are carried out. the result should be a smooth white paste which, 

 when water is added, will strain readily. Dilute the milk of lime with water, so it 

 will be possible to know how many pounds of store-lime is in each gallon of the 

 lime-water. Mark barrel to allow for evaporation, as in the case of the copper- 

 sulphate solution. 



After t] -Muttons have 'been prepared, to make the 4-4-40 Bordeaux 



mixture, proceed as follow- two barrels besides the spray-barrel. In one 



barrel put 1 gallon of the copper-sulphate solution, which, according to the strength 

 of the solution as described ;11 contain 4 Ib. of bluestone. Dilute this I 



gallons by adding 19 gallons of water. In the other barrel pla< lution of 



lime containing 4 Ib. of lime, and dilute with water to make up 20 gallons. Stir 

 both of these well and then pour them into the spray-barrel, so that the two liquids 

 will unite as they enter. By following these directions carefully a Bordeaux mix- 

 ture will be prepared which will stand in - i well, stick well to the tree, and 

 be effective. It is advisabl his mixture within a few hours after making. 

 It is advisable to strain the mixture as it goes into the spray-barrel. For this pur- 

 pose a brass strainer fixed in a cone shape in the bottom of a pail with an outlet is
