“Still, however, there are wanting a few traits to complete this description. A man in health consumes, in the space of twenty-four hours, about eight pounds of victuals and drink: consequently, 8000lb. of provisions are required daily in such a ship. Now, let us suppose a ship to be fitted out for three months only, and we shall find that she must be laden with 720,000lb. of provisions. A large forty-two pounder weighs about 6100lb. if made of brass, and about 5500lb. if iron; and generally there are twenty-eight or thirty of these on board a ship of 100 guns, the weight of which, exclusive of that of their carriages, amounts to 183,000lb.—on the second deck, thirty twenty-four pounders, each of which weighs about 5100lb. and therefore altogether 153,000lb.—the weight of the twenty-six or twenty-eight twelve-pounders on the lower deck, amounts to about 75,400lb.—that of the fourteen six-pounders on the upper deck, to about 26,600lb.—besides which, on the round tops, there are even three-pounders and swivels. Now, if to this we add, that the complete charge of a forty-two pounder weighs about 64lb. and that at least upwards of 100 charges are required for each gun, we shall find this to amount nearly to the same weight as the guns themselves. In addition to this, we must reflect, that every ship must have, by way of providing against exigencies, at least a second set of sails, cables, cordage, and tacklings, which altogether amount to a considerable weight. The stores, likewise, consisting of planks, pitch, and tow; the chests belonging to the officers and sailors; the surgeon’s stores, and various other articles requisite on a long voyage; as also the small arms, bayonets, swords, and pistols, are no inconsiderable load; to which we must finally add the weight of the crew, which is not very trifling: so that one of these large ships carries at least 2162 tons burden, or 4,324,000lb. and at the same time is steered and governed with as much ease as the smallest boat. Now, the consideration of these circumstances alone, is sufficient to excite the most serious reflections in a contemplative mind; and yet, if such a ship sailed along the coast only, and never lost sight of the shore, as the navigators of old used to do, we might still be tempted to look upon navigation as an easy and trifling business. But the finding the straightest and shortest way over an ocean of more than sixty or eighty degrees in longitude, and thirty or forty in latitude; or across a track from 4000 to 6000 miles in extent, by day and by night, in fair weather or in foul; as well when the sky is overcast as when it is clear, and often with no other guide than the compass, and the being able to determine the true position of the ship at sea, by the height of the sun, though this latter be enveloped in clouds, or to direct its course by the moon and stars with such exactness and precision, as not to make a mistake of the value of half a degree, or thirty miles; this at least shews the progress and great perfection of an art practised by a class of people, of whose understanding many conceited and supercilious landsmen have but a mean opinion, and whose plain and simple manners they frequently take the liberty of turning into ridicule, forgetting how much they are indebted to their skill and prowess.
“A violent storm of wind will make us tremble with fear, even in a strong well-built house, and in the midst of a populous city; yet we have seldom or never either seen or experienced the vast power of the enraged waves, when beat about by the winds, and dashed against each other till they seem transformed into froth and vapour, and the whole surface of the ocean presents to the eye a confused scene of immense watery mountains and bottomless precipices; and yet on such a sea as this the true seaman, provided he has but a good ship, rides with calm and unshaken courage, and thinks himself as safe in the midst of the ocean as in the best fortified castle.”
With gallant pomp and beauteous pride,
The floating pile in harbour rode;
Proud of her freight, the swelling tide
Reluctant left the vessel’s side,
And rais’d it as it flow’d.
The waves, with eastern breezes curl’d,
Had silver’d half the liquid plain;
The anchors weigh’d, the sails unfurl’d,
Serenely mov’d the wooden world,
And stretch’d along the main.

CURIOSITIES RESPECTING WATERFALLS, LAKES, GULFS, WHIRLPOOLS, &c.
The Falls of Niagara—Lake of Killarney—Lake Solfatara—Whirlpool near Suderoe—Maelstrom—Gulf Stream—New Island starting from the Sea.
| Fountains and ponds he adds, and lakes immense, Descending streams the winding borders fence; This, deep-absorb’d, the darksome cavern laves, These to the ocean roll their azure waves; There, uncontroll’d, they meet the roaring tide, And dash, for verdant banks, the hoar cliff’s side. Ovid. |
Niagara is a river of the United States, which flows from Lake Erie, and runs by a north-west course into the south-west end of Lake Ontario, constituting part of the boundary between the United States and Canada. It is thirty-four miles long, including its meanders. About twenty miles below Lake Erie is the great cataract, called The Falls of Niagara, which is justly reckoned one of the greatest natural curiosities in the world. These falls run from south-south-east to north-north-west; and the rock of the falls crosses them, not in a right line, but forms a kind of figure like a hollow semicircle, or horse-shoe. Above the falls, in the middle of the river, is an island called Grand Isle, about nine hundred or one thousand feet long, the lower end of which is just at the perpendicular edge of the fall. On both sides of this island runs all the water that comes from the lakes of Canada; viz. Lakes Superior, Michigan, Huron, and Erie. Before the water comes to this island, it runs but slowly, compared with its motion afterwards, when it grows the most rapid in the world, running with a surprising swiftness before it comes to the fall. It is perfectly white, and in many places is thrown high up into the air. At this island, the river divides into two channels: the perpendicular descent of the north-east channel, as measured by Dr. M‘Causlin, is one hundred and sixty-three feet; that of the north-west, one hundred and forty-three; and the breadth of the cataract and island, above a mile.
The water that runs down on the west side is more rapid, flows in greater abundance, and is whiter, than that on the east side, and seems to outfly an arrow in swiftness. At the principal fall, on looking up the river, one may see that the water is every where exceedingly steep, almost like the side of a hill; but upon looking at the fall itself, it is impossible to express the amazement it occasions. The height of it, as measured by mathematical instruments, is exactly one hundred and thirty-seven feet; and when the water is come to the bottom, it rebounds back to a very great height in the air. The noise is heard at the distance of forty-five miles. At fort Niagara, when they hear the noise of the fall more loud than ordinary, they are sure that a north-east wind will follow; which is the most surprising, as the fort lies south-west from the fall. Sometimes the fall makes a much greater noise than at others, and this is held for an infallible sign of approaching rain or bad weather. From the place where the water falls, there arises a great quantity of vapour, like very thick smoke, insomuch, that when viewed at a distance, one would think that the Indians had set the forests on fire. These vapours rise high in the air when it is calm, but are dispersed by the wind when it blows hard. In September and October, such quantities of dead water-fowl are found every morning below the fall, on the shore, that the garrison of the fort live chiefly upon them. Besides the fowls, they find several sorts of dead fish, also deer, bears, and other animals, which have tried to cross the water above the fall: the larger animals are generally found broken to pieces. Just below, a little way from the great fall, the water is not rapid, but goes in circles, and whirls like a boiling pot; which however does not hinder the Indians going upon it in small canoes a fishing; but a little further, and lower, the other smaller falls begin.
