decayed spots on the fruit. These spots increase in extent until the 

 whole fruit is infested. The disease may also attack the flowers, which 

 is sometimes the case, after a year of infestation. The twigs are also 

 susceptible, and the effect upon this part of the host is to produce a 

 blight, the twig being completely killed. Peaches and apricots are more 

 subject to the twig blight than the other stone fruits. R. E. Smith, in 

 Bulletin 203 of the California Experiment Station, recommends for 

 control self-boiled lime-sulphur, just as the fruit is setting, and again 

 after the rains are over. The formula for the self -boiled lime-sulphur, 

 taken from "Injurious Insects," by W. C. O'Kane, consists of lump 

 lime, 20 pounds, over which is poured 3 gallons of cold water ; as soon 

 as the slaking is well started, 20 pounds of flowers of sulphur are added ; 

 begin stirring as soon as this is added, and dilute with cold water until 

 the mass has the consistency of paste. The boiling will subside in from 

 five to fifteen minutes, and more cold water is then added, so that no 

 further action will take place. There should be none of the red liquid 

 indicating the formation of the chemical compounds characteristic of 

 the winter wash. Dilute the mixture until there are 100 gallons in all.
