A GARDENERS DISCOVERY.

A Gloucestershire gardener believes that he has found a cure for silver leaf, one of the most serious of tree maladies. Owing to the order that affected trees must be destroyed, the Victoria plum has almost been wiped out over large districts of Gloucestershire. The history of the discovery is interesting. The gardener took it into his head that the mould which attacks the leaves had its origin in the root, and several years of investigation and experiment went to corroborate the belief. Finally he produced a powder that he and many of his neighbours believe to be a sovereign cure. The method is to bore a narrow hole at a downwards slant into the heart of the tree, about a foot from the ground, fill with the powder (which is of simple composition) and cork up the opening.
