The material here described, when finished, is of the proper strength 
for use as a winter spray, without further dilution. It contains much 
sediment, and must always be carefully strained before use, or it will 
clog the nozzles intolerably. It is the standard formula with many 
fruit growers, and is considered to be especially effective against San 
José seale. 
It is easier to prepare it if facilities are at hand for cooking by steam; 
but the use of large iron kettles is permissible, provided the material 
is stirred constantly and vigorously during the entire time it is cooking. 
Place in the boiler 20 pounds of stone lime. Add a few gallons of 
hot water to start the lime to slaking, and then gradually add 15 pounds 
of flowers of sulphur, stirring constantly. Add 12 gallons of hot water, 
and boil hard for an hour. Dilute with more hot water until there are 
50 gallons of the mixture. Strain carefully, using preferably a brass 
wire strainer with twenty meshes to the inch. Apply the solution 
while still hot.

Kerosene emulsion is a valuable insecticide, especially for destroying 
hibernating insects in rubbish, and, when further diluted, for killing 
plant lice, and other similar insects. The ingredients are kerosene 
(coal oil), soap, and water. By means of the soap the oil is broken up 
into extremely fine particles, or, in other words, is ‘* emulsified,”’ so 
that in effect it may be applied greatly diluted, and its killing power on 
insects secured without injuring plant tissues. 
To prepare, shave up 4 pound of laundry soap in 1 gallon of soft
