number of plum-growers who declare that the cure was absolute, and among the more ardent believers is Mr. MacNamara, the Rector of the Parish of Flaxley. The discoverer's trouble is that he cannot persuade any scientific investigator to test his remedy. I cannot, of course, in any way endorse the claim ; but it is quite clear that there is evidence enough for a scientific trial. There exists in every county an agricultural advisory Board, and there are a number of most excellent Research Stations, any one of which should be glad to investigate, though so far suggestions to this end have failed. One of the difficulties is of the same nature as confronts all claimants to a cure for foot-and-mouth disease. Affected plants, as affected animals, must be destroyed ; and the drastic enforcement of the order automatically liars experiment.
