Remedies.
When the jumpers are in full force upon the hop plants the only remedy available, or that has been proved to be practical and effectual, is to hold tarred boards, or tarred sacking, on two sides of the plants low down in the alleys, and to have the poles tapped smartly with a stout stick. The insects, which are very timid, as may be seen by the way they dodge round the poles, take a mighty leap after this shock and jump into the tar, Thousands can be caught by this means in a day in badly infested plantations. Washing with soap and water does not seem to have much effect upon them.
