This is a disease which attacks the footstalks of the bunches, and appears to he occasioned by the temperature of the soil being much below that of the house in which the vines are growing; the supply of sap to the grapes is consequently much diminished, and the parts to which is given no support immediately begin to decay. The coldness of the soil induces torpidity of root action, and that perhaps at a period when the greatest demand is made upon the roots to sustain the excessive perspiration which is going on in the leaf, and to furnish fresh matter for elaboration. If the young fibres be examined after a season of cold drenching rains, and at inclement periods, they will be found to be discolored, and in some instances to be quite rotten. Consequently, I conceive that shanking is generally caused by the unnatural disagreement of temperament between roots and branches; the way obviously of preventing shanking is to secure a congenial temperature both to roots and foliage. Under great disparity of temperature in these respects, Frontignans are always apt to shrivel and shank. - M. Austin.
