By William Thomson, Tweed Vineyard, Galashiels. Seventh Edition, Enlarged. Blackwood & Sons. The very successful career of this 'Treatise' has brought it to its seventh edition in less than nine years. This edition is enlarged by a chapter on preparing young Vines for planting after the method adopted by the author in planting his extensive vineries on Tweedside; and also by an account, translated from the 'Flore,' edited by Louis van Houtte of Ghent, of the Phylloxera vastatrix, a terribly destructive insect, which, in some instances in this country, has proved fatal to the Vine. The way in which this terrible disease can be eradicated is also detailed.
