him farther reflect, how all these Parts lay when, as our ancient Histories relate, the Danish Fleet came up almost to Hartford, so that all that Range of fresh Marshes which reach for twenty five Miles in length, from Ware to the River Thames, must be a Sea.
In short, Let any such considering Person imagine the vast Tract of Marsh-Lands on both sides the River Thames, to Harwich on the Essex side, and to Whitstable on the Kentish side, the Levels of Marshes up the Stour from Sandwich to Canterbury, the whole Extent of Lowgrounds commonly call'd Rumney-Marsh, from Hythe to Winchelsea, and up the Banks of the Rother; all which put together, and being allow'd to be in one place cover'd with Water, what a Lake wou'd it be suppos'd to make? According to the nicest Calculations I can make, it cou'd not amount to less than 500000 Acres of Land.
The Isle of Ely, with the Flats up the several Rivers from Yarmouth to Norwich, Beccles, &c. the continu'd Levels in the several Counties of Norfolk, Cambridge, Suffolk, Huntingdon, Northampton, and Lincoln, I believe do really contain as much Land as the whole County of Norfolk; and 'tis not many Ages since these Counties were universally one vast Moras or Lough, and the few solid parts wholly unapproachable: insomuch that the Town of Ely it self was a Receptacle for the Malecontents of the Nation, where no reasonable Force cou'd come near to dislodge them.
'Tis needless to reckon up twelve or fourteen like Places in England, as the Moores in Somersetshire, the Flat-shores in Lancashire, Yorkshire, and Durham, the like in Hampshire and Sussex; and in short, on the Banks of every Navigable River.
The sum of the matter is this; That while this Nation was thus full of standing Lakes, stagnated Waters, and moist Places, the multitude of Exhalations must furnish the Air with a quantity of Matter for Showers and Storms infinitely more than it can be now supply'd withal, those vast Tracts of Land being now fenc'd off, laid dry, and turn'd into wholsome and profitable Provinces.
This seems demonstrated from Ireland, where the multitude of Loughs, Lakes, Bogs, and moist Places, serve the Air with Exhalations, which give themselves back again in Showers, and make it be call'd, The Piss-pot of the World.
The imaginary Notion I have to advance on this Head, amounts only to a Reflection upon the Skill of those Ages in the Art of Navigation; which being far short of what it is since arrived to, made these vast Northern Seas too terrible for them to venture in: and accordingly, they rais'd those Apprehensions up to Fable, which began only in their want of Judgment.
The Phœnicians, who were our first Navigators, the Genoese, and after them the Portuguese, who arriv'd to extraordinary Proficiency in Sea Affairs, were yet all of them, as we say, Fair-weather Sea-men: The chief of their Navigation was Coasting; and if they were driven out of their Knowledge, had work enough to find their way home, and sometimes never found it at all; but one Sea convey'd them directly into the last Ocean, from whence no Navigation cou'd return them.
When these, by Adventures, or Misadventures rather, had at any time extended their Voyaging as far as this Island, which, by the way, they always perform'd round the Coast of Spain, Portugal, and France; if ever such a Vessel return'd, if ever the bold Navigator arriv'd at home, he had done enough to talk on all his Days, and needed no other Diversion among his Neighbours, than to give an Account of the vast Seas, mighty Rocks, deep Gulfs, and prodigious Storms he met with in these remote Parts of the known World: and this, magnified by the Poetical Arts of the Learned Men of those times, grew into a receiv'd Maxim of Navigation, That these Parts were so full of constant Tempests, Storms, and dangerous Seas, that 'twas present Death to come near them, and none but Madmen and Desperadoes could have any Business there, since they were Places where Ships never came, and Navigation was not proper in the Place.
And Thule, where no Passage was
For Ships their Sails to bear.
Horace has reference to this horrid Part of the World, as a Place full of terrible Monsters, and fit only for their Habitation, in the Words before quoted.
Belluosus qui remotis
Obstrepit Oceanus Britannis.
Juvenal follows his Steps;
Quanto Delphino Balæna Britannica major.
Such horrid Apprehensions those Ages had of these Parts, which by our Experience, and the Prodigy to which Navigation in particular, and Sciential Knowledge in general, is since grown, appear very ridiculous.
For we find no Danger in our Shores, no uncertain wavering in our Tides, no frightful Gulfs, no horrid Monsters, but what the bold Mariner has made familiar to him. The Gulfs which frighted those early Sons of Neptune are search'd out by our Seamen, and made useful Bays, Roads, and Harbours of Safety. The Promontories which running out into the Sea gave them terrible Apprehensions of Danger, are our Safety, and make the Sailors Hearts glad, as they are the first Lands they make when they are coming Home from a long Voyage, or as they are a good shelter when in a Storm our Ships get under their Lee.
Our Shores are sounded, the Sands and Flats are discovered, which they knew little or nothing of, and in which more real Danger lies, than in all the frightful Stories they told us; useful Sea-marks and Land-figures are plac'd on the Shore, Buoys on the Water, Light-houses on the highest Rocks; and all these dreadful Parts of the World are become the Seat of Trade, and the Centre of Navigation: Art has reconcil'd all the Difficulties, and Use made all the Horribles and Terribles of those Ages become as natural and familiar as Day-light.
The Hidden Sands, almost the only real Dread of a Sailor, and by which till the Channels between them were found out, our Eastern Coast must be really unpassable, now serve to make Harbours: and Yarmouth Road was made a safe Place for Shipping by them. Nay, when Portsmouth, Plymouth, and other good Harbours would not defend our Ships in the Violent Tempest we are treating of, here was the least Damage done of any Place in England, considering the Number of Ships which lay at Anchor, and the Openness of the Place.
So that upon the whole it seems plain to me, that all the dismal things the Ancients told us of Britain, and her terrible Shores, arose from the Infancy of Marine Knowledge, and the Weakness of the Sailor's Courage.
Not but that I readily allow we are more subject to bad Weather and hard Gales of Wind than the Coasts of Spain, Italy, and Barbary. But if this be allow'd, our Improvement in the Art of Building Ships is so considerable, our Vessels are so prepar'd to ride out the most violent Storms, that the Fury of the Sea is the least thing our Sailors fear: Keep them but from a Lee Shore, or touching upon a Sand, they'll venture all the rest: and nothing is a greater satisfaction to them, if they have a Storm in view, than a sound Bottom and good Sea-room.
From hence it comes to pass, that such Winds as in those Days wou'd have pass'd for Storms, are called only a Fresh-gale, or Blowing hard. If it blows enough to fright a South Country Sailor, we laugh at it: and if our Sailors bald Terms were set down in a Table of Degrees, it will explain what we mean.
Just half these Tarpawlin Articles, I presume, would have pass'd in those Days for a Storm; and that our Sailors call a Top-sail Gale would have drove the Navigators of those Ages into Harbours: when our Sailors reef a Top-sail, they would have handed all their Sails; and when we go under a main Course, they would have run afore it for Life to the next Port they could make: when our Hard Gale blows, they would have cried a Tempest; and about the Fret of Wind they would be all at their Prayers.
