phur) into a thick paste with water. Pour this into five gallons of 
hot water, in which twenty-one pounds of quick lime has been slaked. 
Boil with frequent stirring, for forty-five minutes, and add enough 
water to make fifty gallons. This amount could be reduced by reduc- 
ing the proportions. Iron kettles may be used for boiling. The re- 
sulting mixture should be orange or yellow in color. Sometimes 
steam is used for boiling, and barrels are the containers. There is a 
method of making this wash without boiling, which, however, results 
in a less effective compound. It is made as follows: To about ten 
gallons of water in a barrel add 20 pounds of quick-lime, 15 pounds 
of sulphur and ten pounds of washing soda; stir frequently for half 
an hour, and add water to make fifty gallons. Both of these washes 
have caustic properties, and one should avoid allowing them to come 
in contact with the skin. Further, they act upon copper very quickly, 
and therefore, should never be placed in any receptacle made of that 
metal. 
In spraying it is best to use a nozzle which produces a fine mist, 
The Vermorel or Mistry nozzles are both good for this purpose. A 
summer spray of lime-sulphur representing a much-diluted solution, 
I-30, or I-40, is being used with great success as a fungicide; and, 
in most respects, is far superior to the Bordeaux Mixture. When 
tour pounds of Arsenate of Lead is added to 100 gallons of this 
dilute form, it makes a very good combined fungicide and insecticide. 
See in this connection the article on Spraying on page 143 of this 
report.
