Km "muffle beads" as they appear, a yard of considerable extent can be kept clear with little trouble; the larvae do not ai)pearto remain in the heiid more than a week or ten days, and that during the time when the vines are low, the tips within plain sight and easily reached. Fourth. If none of the preceding methods have succeeded in entirely ridding the yard of grubs, and as a matter of precaution, even if no damage from grubs is observed, it is good policy to expose the roots for a few days ; but little trouble is necessary to do this, for before hilling the roots are but scarcely covered, and only enough earth to bare the junction of the growing vine with the old root need be removed. This should be done early in June, when the larvae have left the inside of the vines. They will not eat above ground, and will take 'to the old roots, to which they do little or no harm. Five or six days will be a sufficiently long time to expose the roots; then api^ly a hand- ful of a mixture of coal and wood ashes, or ammoniated phosphate, and hill high. Both of these substances have been used as remedies against the grub, and both successfully by some and unsuccessfully by others; the ditferences are unreconcilable by the fact that in neither case w^as it the application of the ashes or phos- l)hates that destroyed or kept off the grub, but the treatment adopted in conjunction with these applications. If, in addition to the application of any desired fertilizer, the vines are hilled, and the hills made high, the vines will throw off rootlets above the main root and be able to derive sustenance from them, whereas when there are no hills, or the hills are low, when the grub does attack the vine it immediately de- prives it of a part of the necessary sustenance and impairs its vitality. Both the ashes and l)hosphate are repugnant to the grub, but not deadl
