Place all the ingredients together in the boiler with water enoughto cover them three or four inches. Boil one-half hour, or until the compoundresembles very black coffee. Dilute to one-third the final bulk with hot water,or, if cold water is used, add very slowly over the fire, making a stock mixtureto be diluted to the full amount as used. When spraying, the mixture shouldbe perfectly fluid and without sediment. This mixture can be used twice orthree times as strong on deciduous trees when dormant. 568 CALIFORNIA FRUITS: HOW TO GROW THEM. A common outfit in California for cooking the lime, sulphur and BORING IN TWIG, STEM, OR ROOT Peach Twig-Borer or Peach Worm,*— This larva is probablythe most serious insect pest that the California peach grower hashad to contend with.

As soon as the tree begins to grow in the spring the larva be-comes active, eats its way out of its winter home and bores into thenew growing twigs causing them to wither and die. Later genera-tions of the worm attack the fruit and from the two forms of attackmuch loss may accrue to the orchardist. Destruction of the larvae in their winter burrows overcomes alldamage from these pests. This can be accomplished by sprayingwith the lime-sulphur compound in the late winter or very earlyspring when the buds are The Common Borer.—An insect which has done vast injury inthis State is the fiat-headed apple bor
