George Teasdale Teasdale-Buckell, The Complete English Wing Shot
“ It is only necessary to see how artfully grouse butts are placed, in order to make the shooting as easy as possible, to know that the grouse’s flight is a match for the shooter. Successful drivings, or big bags in the day, which is the same thing, require every assistance to be given to the gunner, for in grouse shooting height is an assistance to him, although it is the reverse in pheasant shooting. The reason is that the grouse usually flies too low for a clear sight of it against the sky, and also low enough to make shooting dangerous when the birds cross the line of the butts. ”
