Prevention.

As the fleas rejoice in cloddy ground, or are at least always more plentiful when the soil is rough and unkindly, it is desirable to work well round the plant-centres early, and get a good page 23 season all over the plantation as quickly as possible after poling. Weeds should be banished, both in the plantations and round the outsides. Pieces of old bine should be carefully collected and carried away when the ground is dug in the late autumn and winter, and when the plants are dressed the bits of bine should be taken away from the ground at once.^* Thorough cultivation up to picking time is essential to keep the soil well moved and to prevent weeds, especially near the plant-centres. After a bad attack lime, or soot, or lime ashes, or guano should be put round the plant-centres in October and worked well in.
