The buds will stand as strong a dose of Paris green a^ one pound In 7a gttlloi of water, with an equal amount of freshly-slaked lime atided. in a few davs, the application should Iw renewed, or sooner if the first treatment is washed off by nun. Arsenate of lead is recommended an strong as eight pounds to the bam'l of water. In small gardens, the practice of jarring the beetles from the vines mto an mverted and then d ,ing them into a pan containing coal oil and water, is of value. When ⦠ibs arc found feeding on the leaves, spraying with Paris green or arseni ' .ead in the ordinary atrengths (one pound of Pans green to 160 gallons of w ..c-, or arsenate of lead 2 pounds in 40 gallons of water) will give relief. The destruction of t he grubs ia an important factor in the control of this insect, because every grub killed means one beetle less the fo lowing spring to attack the buds. In addit
