The congress on the phylloxera have arrived at no very
practical result. It seems to be held, that those who have the means of submerging their vines for at least forty-five days continuously in water may cure their vines of the insect plague, though we do not know that they would not be liable to a reinva.- sion by it. But very few have the means of managing this im- mersion, and if they had, a great many of the vines are found to be injured as fruit-bearing trees by the process. Again, sul- phuret of carbon and sulpho-earbonate of potash kill a great many of the insects, if the roots of the vine be well impregnated with either ; but the cost of the first is 218 per acre the first year and 212 afterwards, and of the second, 228 an acre the first year, and 220 an acre afterwards. Neither does either remedy, costly as it is, ensure the plant against insects. Com- pletely killing out the infected vines and importing new kinds seems the best chance ; but that, again, means an enormona waste of capital,
