Nature herself hath decreed that the molens shall remain solitary and cut off from the busy world, for day after day and night after night throughout the year a mist rises from the mud flats around and envelops the molens as in a shroud. In winter the mist is frosty, in summer at times it is faintly tinged with gold, but it is always there and through it the rest of the living world--Ryswyk and 'S Graven Hage and Delft further away only appear as visions on the other side of a veil. Just opposite the molens, some two hundred paces away to the east, the waters of the Schie rush with unwonted swiftness round the curve; so swiftly in fact that the ice hardly ever forms a thick crust over them, and this portion of an otherwise excellent waterway is--in the winter--impracticable for sleighs. Beyond this bend in the river, however, less than half a league away, there is a wooden bridge, wide and strongly built, across which it is quite easy for men and beasts to pass who have come from the south and desire to rejoin the great highway which leads from Delft to Leyden. In the morning of that same fourth day in the New Year, two men sat together in what was once the weighing-room of the molens; their fur coats were wrapped closely round their shoulders, for a keen north-westerly wind had found its way through the chinks and cracks of tumble-down doors and ill-fitting window frames. Though a soft powdery veil--smooth as velvet to the touch and made up of flour and fine dust--lay over everything, and the dry, sweet smell of corn still hung in the close atmosphere, there was little else in this room now that suggested the peaceful use for which it had been originally intended. The big weighing machines had been pushed into corners, and all round the sloping walls swords, cullivers and muskets were piled in orderly array, also a row of iron boxes standing a foot or so apart from one another and away from any other objects in the room. The silence which reigned over the surrounding landscape did not find its kingdom inside this building, for a perpetual hum, a persistent buzzing noise as of bees in their hives, filtrated through the floor and the low ceiling of this room. Men moved and talked and laughed inside the molens, but the movement and the laughter were subdued as if muffled in that same mantle of mist which covered the outside world. The two men in the weighing-room were sitting at a table on which were scattered papers, inkhorns and pens, a sword, a couple of pistols and two or three pairs of skates. One of them was leaning forward and talking eagerly:
