stirring constantly. Now add ten gallons of water and the twenty 
pounds of lime and boil for forty-five minutes. Add water to make 
the twenty-five gallons. When cooled to 65 degrees F. test with 
the Baume scale, the reading should be about 33 degrees. 
Asa scalecide to use in the dormant season this should be 
diluted 1-10 (1. e.) one part of the above formula diluted with 
nine parts of water, and 6-10 pounds of stone lime added to every 
fifty gallons of the spray. 
As a fungicide for summer use dilute 1-30. (One part of stock 
formula diluted with twenty-nine parts of water. ) 
SELF Bormep Lim SUEEUR: 
Lime, 8 pounds. 
Sulfur, 8 pounds. 
Water, 50 gallons. 
This spray is especially valuable in cases where bordeaux 1s 
injurious to foliage or fruit. The stone fruits, such as plums, are 
particularly susceptible to bordeaux injury, while some varieties 
of apples are badly russeted by it. ‘There is slight danger of injury 
by the self boiled lime sulfur preparation and it is an efficient fungi- 
cide when properly made. It stains the fruit as does bordeaux. 
In making it, eight pounds of lime of good quality should be 
placed in a barrel, and enough water to nearly cover it should be 
added. While the lime is slaking, add sulfur which has been run 
through a sieve to break up the lumps. The sulfur should be 
thoroughly stirred into the slaking lime, enough water being added 
to make a pasty mass. The barrel should not be covered, in order to 
retain the heat, and the contents should be occasionally stirred. 
The time required varies with the quality of the lime; if the lime 
acts quickly, five to ten minutes will be sufficient, while if it acts 
slowly, fifteen minutes may be necessary. It should not be allowed 
to stand too long, because it may, in that case, be injurious to 
foliage. Now add a little water, stirring the mixture while it is 
being poured in. Then add enough water to bring the total up to 
50 gallons. In applying the spray it is necessary to have a good 
agitator in the sprayer. 
MiscrsLe O1ixrs (Oils that will mix with water) : 
There are several oils on the market that are miscible with 
water. These make a good winter spray for scales, and are also 
excellent summer sprays against the same insects. Great care, how-
