more water than necessary to make a fluid mass. 

 Strain tlirough a gunny sack and apply hot. 



*'The main point to be insisted on is that the 

 mixture be thoroughly boiled, so as to obtain the 

 complete combination of the sulphur and lime. Hog- 

 scalders were generally used last winter, but in at 

 least one case a small steam boiler proved economical 

 and satisfactory. Where large quantities of the mix- 

 ture are to be prepared, the steam boilers will prob- 

 ably prove most convenient.'' 



For Georgia, Mr W. M. Scott, state entomologist, 

 gives the following directions : 



^'This wash may be prepared by combining lime, 

 salt and sulphur in several different proportions, but 

 the following appears to be the generally accepted 

 formula : 



Quicklime 30 pounds 



Salt 15 pounds 



Flowers of sulphur 20 pounds 



Water to make 60 gallons. 



"Slake half the lime carefully and place it in a 

 large kettle with 25 gallons of water; grind the 

 sulphur up with a little water, breaking the lumps 

 as fine as possible by passing through a sieve and 

 add to the lime; boil. As it boils the liquid will 

 gradually become thinner and thinner, the lime and 

 sulphur dissolving simultaneously to form a deep 

 orange-red solution. When the sulphur has appar- 

 ently all entered into solution, which may take two 

 hours or more, slake the remainder of the lime, add 

 to it the salt, and pour the two into the lime and 

 sulphur solution. Boil the whole for from half an hour 

 to an hour longer, strain, and dilute with warm 

 water to 60 gallons. Do not let it become thoroughly 

 cold, but spray while yet warm.
