Now is the the time of the year when everyone who loves their woods and trees; 'stiffens the sinews, summons up the blood and lends the eye a terrible aspect' (Henry V before Harfleur) and goes out to kill grey squirrels. The grey squirrel is the principal enemy of foresters having an appalling habit of stripping the bark from young trees in the early summer when the sap is rising which leads to, what would in time (hundred years or so ) have become truly great and noble forest trees instead developing into stunted, disfigured, ugly stumps. There is truly nothing more dispiriting to anyone who loves trees than to see a wood they planted fifteen or twenty years earlier, and is finally taking on the characteristics of a wood rather than a plantation, suddenly, in a matter of days, wrecked by an attack of grey squirrels. What puzzles me though is that when I was in America in New England I walked through their woods and saw no squirrels and no sign of damage to any of their hardwoods. Plant American Black Walnut or Red Oak or Sugar Maple over here though, as I have, and you will very soon rue your decision as the grey squirrel will attack them with enthusiasm. So if you love trees and woods kill grey squirrels, by trap, by poisoned bait, or with gun it matters not a jot as long as they are killed.
