For Wireworm in Turnips, it has been found to succeed well to mix sand with just enough paraffin to moisten it slightly— not enough to clog, but still to run in the hand—and to sprinkle this very lightly over the roots by hand. Ashes or dry earth would answer as well as sand. It was found m the Stoke Edith experiments that the Hop-shoots came up without the shghtest injury through a dressing of a bushel of dry material sprinkled with a quart of paraffin; and as the Wire- worms usually feed near the surface, the smell, or the paraffin in dilute state driven down by the rain, would probably soon tell on them. , . , . , Mr. Whitehead mentions in his Eeport previously quoted that, "opening a trench in the autumn after the poles are down, and forming a ring close round the plant-centr^, and putting in earth, ashes or sawdust, saturated with paraffin oil, is an excellent plan in the case of plantations that are bad y infested" {taking care not to put too much oil, lest it should kill the roots). Likewise that "planters who suspect the presence of Wireworms very frequently set a row of Potatoes between the rows of Hop-plants, in order to draw the Wire- worms from the young ; And further, that "dressings of Rape-dust dug in round infested plants will also draw the Wireworms, relieving them for a time, but also tending to collect the Wireworms round or near the plant- ; MANGOLDS.
