PREPARATION OF THE MIXTURE. 



Various formulas for the sulphur and lime mixture have been recom- 

 mended, but most of them call for fifteen pounds of sulphur and the same 

 or a little larger amount of lime. While the use of fifteen pounds of lime 

 will be sufficient to form a chemical compound with the sulphur, it is 

 always well to use a somewhat larger amount as the undissolved lime 

 shows upon the trees and thus makes it easier to be sure that a thorough 

 job has been done. On this account, and because there is always more 

 or less lime that is air-slaked, we have recommended twenty-five pounds 

 of lime and fifteen pounds of sulphur for making fifty gallons of the 

 mixture. At the time t!ie mixture is prepared, however, it is not neces- 

 sary to use more than one-half the amount of water that there will be 

 in the final mixture. If fifty gallons are needed we would recommend 

 the following procedure: Place twenty-five pounds of lime in a barrel 

 or kettle and add hot water until slaking has commenced. When the 

 slaking is well under way, enough water to cover the lime should be sup- 

 plied and the sulphur should then be added. It will be well to first 

 make a thick paste of the suli)hur by the addition of a small quantity 

 of water. The sulphur and lime should then be thoroughly mixed, 

 using a hoe or a shovel, and as soon as the lime has slaked the boiling 

 should begin, after adding water enough to make twenty to twenty-five 

 gallons. While it will generally suffice if the boiling is kept up for forty- 

 five minutes, figuring from the time the mass has been brought to the 

 boiling point, there will be no harm done if it is continued for at least 

 one hour, as if any of the sulphur has not combined with the lime it will
