Remedies.

As to remedial measures, it is somewhat difficult to apply these so as to be of direct and very apparent benefit. When meadows are badly affected dressings of gas lime, or of earth, or wood or coal ashes carefully impregnated with kerosine or page 35 petroleum, should be tried.^* Liquid manure copiously applied has been of much avail on light land. Kainite of potash put on at the rate of half a ton per acre has been found to answer. Rolling heavily and frequently tends to close the ground, and to keep the grubs from the roots in some degree. It may be said that meadows reserved for mowing and not regularly fed by sheep should be rolled more than they are, particularly upon light land, which is more subject to the attacks of cockchafers and other insects than land of clay or other adhesive composition. Folding sheep on grass land long and heavily, especially ewes and lambs, with plenty of artificial food and swedes or mangels carted on, is an admirable remedy against these grubs. The land is made firm so that they cannot work, and it is soaked with liquid, which they cannot bear.

Corn crops are often attacked by these grubs after sainfoin leys, and clover leys that have been down longer than the usual period. In wheat land showing signs of loss of plant many grubs were discovered, though the finder had no idea what they were. He was advised to horse hoe well, and to put on five hundredweights of kainite of potash and one hundredweight of nitrate of soda, and after this to roll heavily. This treatment was effectual. Soot has been also found very useful chopped in with hand hoes, and the land rolled down tightly afterwards. Nitrate of soda was usefully employed by itself in another case after ring rolling both ways, and a heavy plain roll put on finally.
