The winter in Russia, as in other parts of Europe has been one of unusual severity. Dr. A. Philibert, of Moscow, writing to Jean Sisley, of Lyons, France, speaks of the probable injuiy to fruit trees, and of numbers that were cut down under the the impression that they were frost-killed in the severe winter of 1860, the trunks of which afterwards grew, - and therefore says he, "it will be imprudent to prune anyhow, but wait first to see if they are really dead. This seems strange advice to those who have American experience: we know that trees die in winter from excessive evaporation, and that moisture dries faster from a dead or dying branch than from a sound one. The sooner a frost-injured branch is cut away the better for the parts that are left. No doubt the trees that lived in 1860 lived because of the pruning they received.
