The maximum pressure is not uniform from the ground level to the roof but is greatest at the centre; it is diminished near the ground level by the frictional resistance of the ground, and at the eaves by the eddies formed by the air escaping over the roof.
The level of the roadway is considerably lower than the ground-floors of the houses, which have generally arched rooms in front, with little shops behind them; and above these they are richly embellished with verandahs, galleries, projecting oriel windows, and very broad overhanging eaves supported by carved brackets.
If roots have been placed in cellars, attention must be given to ventilation, which can be done by making a wooden box, say 6 by 8 in., to run from the ceiling of the cellar to the eaves of the building above.
The houses in the principal streets are built of hewn stone, and are several storeys high, with projecting eaves that give shelter from both sun and rain.
Meanwhile, the wind whistled around the eaves and rattled the plastic covering on the windows, persistently seeking a port of entry.
Suddenly an influx of light filled my house, though the evening was at hand, and the clouds of winter still overhung it, and the eaves were dripping with sleety rain.
Some two years prior to my first learning the events which I am about rehearsing to you, gentlemen, the Town-Ho, Sperm Whaler of Nantucket, was cruising in your Pacific here, not very many days' sail eastward from the eaves of this good Golden Inn.
The town itself is fan-shaped, the streets, which contain some fine old houses with projecting eaves and many towers, radiating from the citadel (Fortezza), which was constructed in 1502, and dismantled by the French in 1800.
The forms of roof are various, but mostly they commence in a steep slope at the top, gradually flattening towards the eaves so as to produce a slightly concave appearance, this concavity being rendered more emphatic by the tilt which is given to the eaves at the four corners.
