HURRICANES:
The West-Indians agree, that August and September is the Season to expect them. They are incredible Tempests of Wind, whose Fury, neither Ships, Masts, Trees, or Buildings can resist. They come a Day or two before the full or new Moon next the Autumnal Equinox, and give Warning by a preceding unusual Swell of Water. They are of no great Extent, but blow within a Chanel as it were, one Island feeling it, when the next (within 20 Leagues perhaps) has no Share; and are, if not peculiar, rarely met with out of the West-Indies.
The Cause, as guessed at, is Plenty of elastic Vapors on the Terra Firma (whence they all blow) with which conspire at this time of year, the united Force of the Sun and Moon, to give their Explosion a greater Force; to this also may contribute, subterraneous Heats and Mountains: and if such different Effluvias as constitute the Matter of a Hurricane, can be supplied to the Chanel it blows in, crescit eundo.
This Opinion seems confirmed, first, from the Points of the Compass they blow on (S E. and S S E.) and never without side the Continent at Cape Roque; for that Length the uninterrupted Trade-Wind is a Barrier, and from which these Storms, by the Position of Lands and Mountains, are necessarily a Deflection. Second, Æquinoctial Gales, we know, are every where observed to happen, and ascribed to the greater Agitation of Air, by Heat in a greater Orb; when therefore the Northern Suns have so long together been attracting, and at the same time chopping, and opening the Earth for a freer Emission of nitrous, sulphurous, and elastic Particles, no wonder the conjoined Forces of the Planets there, should now and then put them in execution.
The present Hurricane was a Week after our Arrival; began at eight in the Morning, two Days before the Change of the Moon, gave at least 48 Hours notice, by a noisy breaking of the Waves upon the Kays, very disproportioned to the Breeze, a continued Swell, without Reflux of the Water; and the two Nights preceding, prodigious Lightnings and Thunder; which all the old experienced Men foretold would be a Hurricane; or that one already had happened at no great distance.
I was ashore at Port-Royal, and found all the Pilots returned from the Windward part of the Island, (where they customarily attend the coming down of Ships,) and observing upon the unusual Intumescence of the Water, so great the Day before, and beat so high, that our Boats could not possibly put on shore at Gun Kay to take the Men off that were set there, to the Number of twenty, for trimming up our Cask; themselves making Signals not to attempt it. Betimes next Morning, the Wind began in Flurrys at N E. and flew quickly round to S E. and S S E. where it continued the Stress of the Storm, bringing such Quantities of Water, that our little Island was overflowed 4 foot at least; so that what with the fierce driving of Shingles (wooden Staves used instead of Tiling upon their Houses) about our Ears, and the Water floating their Boats, empty Hogsheads, and Lumber about the Streets, those without doors were every Moment in danger of being knocked on the Head, or carried away by the Stream. Within it was worse, for the Waters sapping the Foundations, gave continual and just Apprehensions of the Houses falling, as in effect half of them did, and buried their Inhabitants: Nor indeed after the Storm had began, was it safe to open a Door, especially such as faced the Wind, lest it should carry the Roofs off; and escaping thence, there was no place of Retreat, we remaining in a very melancholly Scituation both from Wind and Water. The Perils of false Brethren was nothing to it.
It may be worth notice, what became of the Purser in this common Danger; I was regardless at first, as suspecting more of Timidity in the People, till finding my self left alone Proprietor of a shaking old House, the Streets full of Water and Drift, with Shingles flying about like Arrows; I began to meditate a little more seriously upon my Safety, and would have compounded all my Credit in the Victualling, my Hoops, and Bags, for one Acre (as Gonzalo says in the Tempest) of barren Ground, long Heath, or brown Furze, to have trod dry upon.
Our Neighbours had retreated towards the Church, as the strongest Building, and highest Ground, which I was luckily too late to recover; but endeavouring to stem upwards for a safer Station, was taken into a House in the lower Street, with an old Woman wading in the same manner from her ruined Habitation.
