We find the following in the LondorL Journal of Horticulture: " Owing to the disastrous effects of the Phylloxera in the French vineyards, the desirability of importing stocks from America was urged on the ground that the vigorous character of the American varieties were by that insect invulnerable. This appears, however, to be simply ' tall talk,' for a correspondent in the Prairie Farmer reports that he has recently taken up 2,000 vines in nearly twenty varieties, and that every sort was infested; the strong growers, however, being the most free from the pest, but all were attacked. The ' little villains were found on the roots by millions." Our cotemporary has not clearly seen the point of the case. The report of Mr. Planchon, and on which the demand - not exactly for American kinds, but for two of them, Concord and Clinton, - was brought about, showed, not that these two were not attacked, but that their rapid rooting and fibrous character enabled them to resist the attacks of the insect more successfully.
Professor Planchon was well aware that the phylloxera attacked these two varieties, and yet their value as stocks is much more than "tall talk," and for the reasons given.
