As this is a very common practice the grubs are consequently often a serious menace.
The possible damage can usually be greatly minimized by cultural methods such as fall plowing or by planting the area to corn or clover the first year. Pasturing hogs 33 in the area is often resorted to. J. F. Illingsworth, an Australian entomologist, has recently obtained remarkable results by the use of crude white arsenic, applying eighty pounds per acre. This method of control is based upon the fact that in... feeding a large amount of soil passes through the intestinal tract of the grub. By mixing the arsenic with the soil, when preparing the seed bed, almost perfect control may be expected. No detrimental effect upon plant growth was noticed even when the arsenic was used in excessive amounts.
PALES WEEVIL It is practically useless to start a coniferous nursery on a white pine area that has just been cut or on a plot that is contiguous to such an area. The pales weevil, {Hylobius pales) which is a snout beetle, is attracted in large numbers to areas where freshly cut pine stumps, logs, boards, or even slash occur.
