They tell of the danger that lurks on the steep slopes of grass, where the mowers have to go down with ropes around their waists, and in the beds of the streams where the floods sweep through in the spring, and in the forests where the great trees fall and crush men like flies, and on the icy bridges where a slip is fatal, and on the high passes where the winter snowstorm blinds the eyes and benumbs the limbs of the traveller, and under the cliffs from which avalanches slide and rocks roll. They show you men and women falling from waggons, and swept away by waters, and overwhelmed in land-slips. In the corner of the picture you may see a peasant with the black cross above his head--that means death. Or perhaps it is deliverance that the tablet commemorates--and then you will see the miller kneeling beside his mill with a flood rushing down upon it, or a peasant kneeling in his harvest-field under an inky-black cloud, or a landlord beside his inn in flames, or a mother praying beside her sick children; and above appears an angel, or a saint, or the Virgin with her Child.
