A strong wind from the northwest is gathering the snow into picturesque drifts behind the walls. As usual they resemble shells more than anything, sometimes prows of vessels, also the folds of a white napkin or counterpane dropped over a bonneted head. There are no such picturesque snow-drifts as are formed behind loose and open stone walls. Already yesterday it had drifted so much, i.e. so much ground was bare, that there were as many carts as sleighs in the streets . . .
