CHAPTER VI. LAKES.

Lake Superior is the largest body of fresh water in the world, being four hundred miles in length, one hundred at its greatest breadth, and, according to the most moderate computation, over twelve hundred miles in circumference. Its shores are rocky and uneven, and it has a rocky bottom. Its waters are pure and transparent, and it has been remarked, that, although during the summer, the waters on its surface be warm, nevertheless, by letting a cup down about a fathom, water may be taken up nearly as cold as ice. It abounds in fish, particularly sturgeon and long trout, many of which are from fifty to seventy pounds weight, and constitute the principal food of the Algonquin Indians on its borders. This lake has five large islands,17 one of which, called Isle Royal, is not less than a hundred miles in length, and in some places forty in breadth. More than forty rivers discharge themselves into it, the two largest called the Nipegon and the Michipicooton, from the north and north-east sides. Asmall river which runs into it, not far from the Nipegon, falls from the top of a mountain more than six hundred feet perpendicular; appearing at a distance, to use Mr.Carver’s homely comparison, like a white garter suspended in the air. On the banks of one of the rivers which fall into its south side, virgin copper has been found. The storms which occur on this lake are felt as severely as on the Atlantic, the waves run equally high, and the navigation is perhaps more dangerous.18 When the wind blows from the east, the waters are driven against the high rocks of the northern and western shores, where they form a thick vapor resembling rain; and this action of the wind creates an irregular ebb and flow. This never exceeds ten or twelve inches; but the strong traces of the water on the rocks of the shore show, that, at no very remote period, they were elevated six feet above the present level. Mackenzie states, that some years ago the waters suddenly withdrew near the Great Portage; then rushed back with great velocity above the common mark; and, after rising and falling during several hours, they settled at their usual level.

Notwithstanding its being fed by so many rivers, Lake Superior has but one outlet by the Straits of St.Mary. At the upper end of these straits, there is a rapid which cannot be ascended, but has sometimes been descended, although the descent requires both skill and caution, and perhaps not a little good fortune. Acanal has been cut by the North-West Company, along the northern banks, for the purpose of facilitating their commerce, and they have here a considerable establishment; but their chief fort and storehouses are situated at Kamenestiquia, on the banks of a river which flows into Lake Superior, on the north-west side, and affords an easy communication with the interior. The Strait of St.Mary, it is supposed, does not discharge one tenth of the waters which the lake receives from its numerous rivers; part of the remainder escapes by evaporation, but how the whole is discharged is yet a secret. It does not appear, however, that an exact calculation has hitherto been made, either of the quantity discharged or the quantity received. This lake lies between forty-six and fifty degrees north latitude, and eighty-four and ninety-three degrees west longitude.

Lake Huron, into which you enter by the Straits of St.Mary, is next in magnitude to Lake Superior. It lies between forty-three and forty-six degrees north latitude, and between eighty and eighty-five degrees west longitude; in shape it is nearly triangular, and its circumference is about a thousand miles. On the Canada side of this lake is an island one hundred miles in length, and no more than eight in breadth; it is called Manataulin, signifying a place of spirits, and is considered as sacred by the native Indians. About the middle of the south-west side of the lake is Saginaw Bay, about eighty miles in length, and twenty broad; Thunder Bay, so called from the continual thunder heard there, lies about half way between Saginaw Bay and the north-west corner of the lake: it is about nine miles across either way. The fish are the same as in Lake Superior. The promontory that separates this lake from Lake Michigan is a vast plain, more than one hundred miles long, and varying from ten to fifteen miles in breadth. At the north-east corner, this lake communicates with Lake Michigan by the Straits of Michilimackinac. It is very remarkable, that although there is no daily flood or ebb to be perceived in the waters of these straits, yet from an exact attention to their state, a periodical alteration in them has been discovered. It has been observed that they rise by gradual, but almost imperceptible degrees, till in seven years and a half they had reached the height of about three feet; and in the same space of time they gradually fell to their former state; so that in fifteen years they had completed this revolution. This, however, is not well established.19

Lake Michigan, formerly called Lake Illinois, and Lake Dauphin, extends from the western angle of Lake Huron in a southerly direction, and is separated from Lake Superior by the tongue of land which is described above. It lies wholly within the territory of the United States, between the parallels of forty-two and forty-six degrees. Its waters are said to be unfathomable. At the southern extremity of Lake Michigan is Chicago Creek, by which, in the rainy season, the head-waters of the Illinois communicate with the lake; but the bar at the mouth of the creek does not admit boats drawing above two feet of water. Anumber of streams flow into the lake, on both the western and the eastern sides. It abounds, like the others, with excellent fish.

‘Lake Michigan,’ says Mr.Schoolcraft, ‘from its great depth of water, its bleak and unguarded shores—and its singular length and direction, which is about four hundred miles from north to south, appears to be peculiarly exposed to the influence of the currents of the atmosphere, to whose agency we may attribute, at least in part, the appearances of a tide, which are more striking upon the shores of this, than of any of the other great lakes. The meteorological observations which have been made, in the Transalleghanian states, indicate the winds to prevail, either north or south, through the valley of the Mississippi; but seldom across it, so that the surface of this lake would be constantly exposed to agitation, from the atmosphere. These winds would almost incessantly operate, to drive the waters through the narrow strait of Michilimackinac, either into Lake Huron or Lake Michigan, until, by their natural tendency to an equilibrium, the waters thus pent, would react, after attaining a certain height, against the current of the most powerful winds, and thus keep up an alternate flux and reflux, which would always appear more sensibly in the extremities and bays of the two lakes; and with something like regularity, as to the periods of oscillation; the velocity of the water, however, being governed by the varying degrees of the force of the winds.’

Lake St.Clair lies about half way between Lakes Huron and Erie, and is about ninety miles in circumference. It receives the waters of the three great lakes, Superior, Michigan, and Huron, and discharges them through the river or strait called Detroit, into Lake Erie. It is of a circular form, and navigable for large vessels, except a bar of sand toward the middle, which prevents loaded vessels from passing.

Lake Erie is situated between forty-one and forty-three degrees of north latitude, and between seventy-nine and eighty-three degrees west longitude. It is two hundred and eighty miles long; opposite Cleveland, in the state of Ohio, it is about sixty miles broad, to the eastward it is above seventy. The average breadth is from fifty to sixty miles; and its medium depth from forty to one hundred and twenty feet. The water is pure and wholesome, and abounds with fish; such as sturgeon, white-fish, trout, and perch. The lake does not freeze in the middle, but is frequently frozen on both sides; and sometimes in winter, when the wind is variable, the ice exhibits a singular phenomenon; a south wind blows it all to the Canada shore, and a north wind again dislodges it, and brings it back to the American side. There are a number of islands in the west end of the lake, containing from eight hundred to two thousand acres of land, and the scenery amongst them is charming; but all these islands are so infested with snakes, that in the height of summer it is really dangerous to land. This is the more to be regretted, as the fine timber which grows upon them indicates that the soil must be uncommonly fertile. But, in defiance of the snakes, many of the islands are rapidly settling, and are found to be very healthy and agreeable places of residence. This and the other lakes are navigated by vessels of from seventy to eighty tons, which carry goods and provisions as far as the head of Lake Superior, and bring back furs and peltry. The navigation is good through the whole distance, except in Lake St.Clair, where the water is shallow, and vessels are sometimes obliged to lighten.

Lake Ontario is situated between forty-three and forty-four degrees of north latitude, and between seventy-six and eighty degrees west longitude. It is about two hundred miles in length and forty in width; its form nearly oval, and its circumference about six hundred miles. It abounds with fish of an excellent flavor, among which are the Oswego bass, weighing three or four pounds. Near the south-east part it receives the waters of the Oswego river, and on the north-east it discharges itself into the St.Lawrence. It is never entirely closed by ice, and is computed from some soundings to be five hundred feet deep. The Ridge Road, or Alluvial Way, is a remarkable ridge extending along the south shore of this lake, from Rochester on the Gennessee to Lewiston on the river Niagara, eighty-seven miles. It is composed of common beach sand and gravel stones worn smooth, and these are intermixed with small shells. Its general width is from four to eight rods, and it is raised in the middle with a handsome crowning arch, from six to ten feet. Its general surface preserves a very uniform level, bring raised to meet the unevenness of the ground which it covers. At the rivers Gennessee and Niagara, its elevation is about one hundred and twenty or thirty feet; and this is its elevation above Lake Ontario, from which it is distant between six and ten miles. There seems to be no way of accounting for this ridge, without supposing that the surface of Lake Ontario was one hundred and thirty feet higher at some former period than it is at present. There is a similar ridge for one hundred and twenty miles, on the south side of Lake Erie.

Lake Champlain lies between the states of New York and Vermont, and communicates with Lower Canada by the river Sorelle, which falls into the St.Lawrence forty-five miles below Montreal. It is about one hundred and twenty miles in length, and of various breadths: for the first thirty miles, that is, from South river to Crown Point, it is nowhere above two miles wide; beyond this, for the distance of twelve miles, it is five or six miles across, it then narrows, and again at the end of a few miles expands. That part called the Broad Lake, commences about twenty-five miles north of Crown Point, and is eighteen miles across in the widest part. Here the lake is interspersed with a great number of islands, the largest of which, named South Hero, is fifteen miles in length, and averages four in breadth. The soil of this island is very fertile, and more than seven hundred people are settled upon it. The Broad Lake is nearly fifty miles in length, and gradually narrows till it terminates in the river Sorelle. Lake Champlain, except at the narrow parts at either end, is in general very deep; in many places sixty and seventy, and in some even a hundred fathoms. The scenery along various parts of the lake is extremely beautiful, the shores being highly ornamented with hanging woods and rocks, and the mountains on the western side rise up in ranges, one behind the other, in the most magnificent manner.

Remains of Forts Ticonderoga and Crown Point, important positions during the old French wars, are found at two great bends of this lake. On the 11th of September, 1814, Commodore McDonough, commander of the American fleet, gained a complete victory over the British fleet in Cumberland Bay, directly in front of the town of Plattsburg.

This lake opens a ready communication between New York and the country bordering on the St.Lawrence. Through the town of Whitehall, which stands at the head of the lake, a considerable trade is carried on across Champlain with Lower Canada. On the British end of the lake, one hundred and fifty miles from Whitehall, stands the garrison town of St.John’s.

Lake George, which discharges itself into Lake Champlain, is the most beautiful sheet of water in the whole country. It is thirty-six miles long, and from two to four broad. It is situated in the eastern part of the state of New-York. Its waters are deep and remarkably transparent, and from their extreme limpidness, the French gave them the name of the Lake of the Holy Sacrament. The shores consist of abrupt and shelving points, and are bounded by two long ranges of mountains,20 sometimes rising boldly from the water, and at others ascending with a gentle and graceful sweep, exhibiting naked and weather-beaten cliffs and wild forests, intermixed with fine cultivated fields, lawns and pastures. The village of Caldwell stands on the south-eastern side of the lake, and is much visited by travellers who come to enjoy the fine scenery in the neighborhood. A steam-boat plies upon the lake in summer.

The islands of the lake are said to be three hundred and sixty-five in number. They are of every form and size, and contribute greatly to the romantic beauty of its surface. Some of them are covered with trees, others are thinly wooded, and others are abrupt and craggy rocks. Diamond Island abounds in crystals of quartz. Long Island contains one hundred acres, and is under cultivation. At a place called the Narrows, the lake is contracted, and its surface is covered with a most beautiful cluster of islands which extends for several miles. Some of them are covered with trees, some show little lawns or spots of grass, heaps of barren rocks, or gently sloping shores; and most of them are ornamented with pines, hemlocks, and other tall trees, solitary or in groups, and disposed with the most charming variety. Sometimes an island will be found just large enough to support a few fine trees, or perhaps a single one, while the next may appear like a solid mass of bushes and wild flowers; near at hand, perhaps, is a third, with a dark grove of pines, and a decaying old trunk in front of it; and thus, through every interval between the islands, as you pass along, another and another labyrinth is opened to view, among little isolated spots of ground, divided by narrow channels, from which it seems impossible for a man who has entered them ever to find his way out. Some of the islands look almost like ships with their masts; and many have an air of lightness, as if they were sailing upon the lake.

After passing the Narrows, the lake widens again, and the retrospect is for several miles through that passage with ranges of rounded mountain summits appearing at a great distance between them. The lake contains abundance of the finest perch, bass, and other fish; trout are found in a stream flowing into the southern part. Near the southern shore, are the ruins of Fort William Henry and Fort George, celebrated in the early wars of the French.

The state of New-York contains a vast number of small lakes. There is scarcely a stream in the northern part of this state, but that has its source in one of these, or runs through several in its progress, whether to the great lakes or to Hudson’s river. Seneca Lake, in the western part of the state, is about thirty-five miles in length, from two to four in breadth, and of great depth. The water of this lake has a gradual periodical rise and fall, once in several years, the cause of which has never been ascertained. The view from the height of land between Seneca and the adjacent lakes is extensive and agreeable. Cayuga Lake is thirty-eight miles long from north to south, and from one to four miles wide; in some places the shore of this lake is precipitous, but in general it is a gentle declivity from the surrounding country to the water. The waters are somewhat shallow, but sufficient for navigation. Several steam-boats ply upon them, and are often crowded by water parties in the fine season. Abridge of a mile in length crosses the north end of the lake.

Oneida Lake is a beautiful sheet of water, twenty miles long and four broad. It is famous for the abundance and excellence of its fish. ‘Imade a small excursion along the border of this lake,’ says Mr.Schultz, ‘and although the shore was low, yet Ifound a firm, dry, white, sandy beach to walk upon; some other parts of it, however, Iwas informed, were low and swampy. Iwas much amused in the evening by a singular illumination upon the lake, which Iwas at first wholly unable to account for. The water at this part of the lake, it seems, is very shallow for nearly half a mile from the shore, and being perfectly transparent, and the bottom a white sand, the smallest object may be readily distinguished. The Indians have a method of taking salmon and other fish by means of an iron frame fixed in the bow of the canoe, projecting forward three or four feet, and elevated about five; upon this they kindle a bright fire of pine knots, and while one person sits in the stern with a paddle to impel the boat forward, another stands in the bow with a sharp spear ready to strike the fish who play about the light. Ten or twelve of these canoes moving about irregularly on the lake, on a fine calm evening, with the reflection of their lights, like so many lines of fire, extending from each object to a centre on which you stand, afford a most pleasing prospect, and far exceeds in my opinion the most brilliant display of artificial fireworks.’

Among the smaller lakes of New York are Onondago, Skeneatiles, Owasco, Canandaigua, Otsego, Caniadebago, Oswegatchie, Cross, Hemlock, Hanyaga, Canesus, Crooked, and Chatauque. The latter is the most western of all these lakes, near the north-east extremity of Lake Erie; it is only eight miles distant from its shore, and the descent to Lake Erie is by an easy slope. From this small lake issues one of the branches of the Alleghany river, called Conewango, which is navigable for small craft in all its extent.

New Hampshire contains several fine lakes, the largest of which is Winnipiseogee, situated east of the centre of the state, and towards the west side of Strafford county. It is a picturesque sheet of water, of irregular form, twenty-two miles in length, and varying in breadth from one to ten miles. Several long capes stretch into it from both sides, almost dividing it into several parts. From the southern extremity of this lake to the north-west corner, there is good navigation in the summer, and generally a good road in the winter; the lake is frozen about three months in the year, and many sleighs and teams, from the surrounding towns, cross it on the ice.

Dr.Dwight has described this lake, as it appears from the top of Red Mountain, with his usual felicity. ‘Immediately at the foot of the height on which we stood, and in the bottom of the immense valley below, spread south-eastward the waters of the Winnipiseogee in complete view; except that one or two of its arms were partially concealed by intervening peninsulas. Afiner object of the same nature was perhaps never seen. The lakes, which Ihad visited in my northern and western excursions, were all of them undivided masses, bordered by shores comparatively straight. This was, centrally, a vast column, if Imay be allowed the term, twenty-three miles in length, and from six to eight in breadth, shooting out with inimitable beauty a succession of arms, some of them not inferior in length to the whole breadth of the lake. These were fashioned with every elegance of figure, bordered with the most beautiful winding shores, and studded with a multitude of islands. Their relative positions, also, could scarcely be more happy.

Winnipiseogee Lake

‘Many of the islands are large, exquisitely fashioned, and arranged in a manner not less singular than pleasing. As they met the eye, when surveyed from this summit, they were set in groups on both sides the great channel, and left this vast field of water unoccupied between them. Their length was universally at right angles to that of the lake; and they appeared as if several chains of hills originally crossing the country in that direction, had, by some convulsion, been merged in the water so low, that no part of them was left visible, except the oblong segments of their summits. Of those, which, by their size and situation, were most conspicuous, Icounted forty-five, without attempting to enumerate the smaller ones, or such as were obscured. The points, which intrude into this lake, are widely different from those of Lake George; bold, masculine bluffs, impinging directly upon the water. These, in several instances, were spacious peninsulas, fitted to become rich and delightful residences of man, often elevated into handsome hills, and sloping gracefully into the lake.’

Umbagog Lake is situated partly in the north-east corner of the state, and is next in size to Winnipiseogee; it lies chiefly in Maine. The others of New Hampshire are Ossipee, Sanapee, Squam, and Newfound.

There are several large, and a vast number of small lakes in the state of Maine. Moosehead Lake, the largest in New England, is the source of the east branch of the Kennebeck, and is fifty miles in length by ten or fifteen in breadth. Sebago Lake, in Cumberland county, is twelve miles long. Chesuncook Lake is twenty miles long and three broad. In Vermont, besides Lake Champlain, which separates this state from New York on the west, there are other lakes of minor importance, deserving of notice. Lake Memphremagog, thirty-five miles in length and three wide, lies chiefly in Canada, and communicates with the St.Lawrence by the river St.Francis. Willoughby Lake, six miles long and one wide, discharges its waters into Memphremagog by the river Barton. This lake furnishes fish resembling bass, of an excellent flavor, weighing from ten to thirty pounds.

A number of small lakes occur towards the sources of the Mississippi. Lake Pepin is an expansion of this mighty river, about one hundred miles below the Falls of St.Anthony. It has been very fully and beautifully described by Mr.Schoolcraft.

‘It is twenty-four miles in length, with a width of from two to four miles, and is indented with several bays, and prominent points, which serve to enhance the beauty of the prospect. On the east shore, there is a lofty range of limestone bluffs, which are much broken and crumbled, sometimes run into pyramidal peaks, and often present a character of the utmost sublimity. On the west, there is a high level prairie, covered with the most luxuriant growth of grass, and nearly destitute of forest trees. From this plain several conical hills ascend, which, at a distance, present the appearance of vast artificial mounds or pyramids, and it is difficult to reconcile their appearance with the general order of nature, by any other hypothesis. This lake is beautifully circumscribed by a broad beach of clean washed gravel, which often extends from the foot of the surrounding highlands, three or four hundred yards into the lake, forming gravelly points, upon which there is a delightful walk, and scalloping out the margin of the lake with the most pleasing irregularity. In walking along these, the eye is attracted by the various colors of the mineral gems, which are promiscuously scattered among the water-worn debris of granitic and other rocks, and the cornelian, agate, and chalcedony, are met with at every step. The size of these gems is often as large as the egg of the partridge, and the transparency and beauty of color is only excelled by the choicest oriental specimens. There is no perceptible current in the lake, during calm weather, and the water partakes so little of the turbid character of the lower Mississippi, that objects can be distinctly seen through it, at the depth of eight or ten feet.

‘In passing though Lake Pepin, our interpreter pointed out to us a high precipice, on the east shore of the lake, from which an Indian girl, of the Sioux nation, had, many years ago, precipitated herself in a fit of disappointed love. She had given her heart, it appears, to a young chief of her own tribe, who was very much attached to her, but the alliance was opposed by her parents, who wished her to marry an old chief, renowned for his wisdom and his influence in the nation. As the union was insisted upon, and no other way appearing to avoid it, she determined to sacrifice her life in preference to a violation of a former vow, and while the preparations for the marriage feast were going forward, left her father’s cabin, without exciting suspicion, and before she could be overtaken threw herself from an awful precipice, and was instantly dashed to a thousand pieces. Such an instance of sentiment is rarely to be met with among barbarians, and should redeem the name of this noble-minded girl from oblivion. It was Oola-Ita.’

Cassina or Red Cedar Lake derives some importance from having been designated as the true source of the Mississippi river. It is about eight miles long and six in breadth, and presents a beautiful sheet of transparent water. On its banks are elm, maple, and pine trees, fields of Indian rice, rushes and reeds; in other places there is an open beach of clean pebbles. Pike, carp, trout and cat-fish are caught in its waters. Towards its western extremity is an island covered with trees, from which it derives its name, though no red cedar is found around its shores.

Turtle Lake, Little Winnepeg Lake, Leech Lake, Swan Lake, Sandy Lake, Muddy Lake, Lake Peckagama, and White Fish Lake, are all near the source of the Mississippi. Anarrow belt of high land separates Turtle Lake, the most northern source of the Mississippi, from Red River Lake, one of the sources of the Red river which runs into Hudson’s Bay. Otter Tail Lake is the most southern source of Red river; and from thence is a portage of only half a mile to a branch of Raven river, which falls into the Mississippi. The whole tract of high country, at the sources of the Mississippi and Red river, is full of marshes, morasses, and small lakes, whose waters afford never failing supplies to these streams.

The Lake of the Woods is of a circular figure, with a cluster of islands in the centre. The navigating course through the lake, is seventy-five miles; but, in direct distance, it is not above two-thirds of that extent in diameter. Its scenery is wild and romantic in a high degree. Its surface is covered with islands. From this lake there is a long succession of small lakes, and numerous portages, to the north-west end of Lake Superior, the chief of which is Rainy Lake. Two small lakes, Lake Biddle, which gives rise to the Big Horn river, and Lake Eustis, which is the source of the Jaune, or Yellow Stone river, are situated amongst the Rocky Mountains, in west longitude one hundred and twelve degrees, and north latitude forty-two degrees.

In the state of Louisiana are the lakes of Maurepas and Pontchartrain. The first of these is of a circular figure, twelve feet deep, and fourteen miles in diameter. In the time of high floods, it has a communication with the Mississippi, by means of the river AmitÉ, or Ibberville; and this inundation, which lasts only four months annually, occasions what is erroneously called the island of New Orleans, to be then an island in fact, for at no other time is it environed with water, the city of New Orleans being situated on a peninsula.21 Lake Maurepas communicates with Lake Pontchartrain, by a stream seven miles long, and three hundred yards wide, and divided by an island extending from the lake to within a mile of Pontchartrain, into two branches, of which the southern is the safest and deepest. Lake Pontchartrain is nearly of a circular form, forty miles in its greatest length, and thirty miles in its greatest breadth, and eighteen feet deep. From this lake to the sea is ten miles, by a passage called the Regolets, four hundred yards wide, and lined with marshes on each side.

On the west side of the Mississippi are the lakes of Great and Little Barataria. The Catahoola Lake, sixteen miles long, and four broad, is the source of a stream of the same name, which, uniting with the Washita and Bayou Tenza rivers, form the Black river. This lake, during the dry months, is covered with the most luxuriant herbage; and is then the residence of immense herds of deer, and water-fowl, which feed on the grass and grain. The other lakes of Louisiana are Calcasin, Borgne, and Bistineau.

GENERAL REMARKS ON LAKES.

Extensive accumulations of water, surrounded on all sides by the land, and having no direct communication with the ocean, or with any sea, are called lakes. Lakes are of four distinct kinds. The first class comprehends those which have no issue, and which do not receive any running water. These are generally very small, and do not merit much attention. The second class comprises those lakes which have an outlet, but which do not receive any running water. These lakes are fed by a multitude of springs; they are naturally on great elevations, and are sometimes the sources of great rivers. The third class of lakes is very numerous, consisting of all such as receive and discharge streams of water. Each of the lakes of this class may be looked upon as forming a basin for receiving the neighboring waters; they have in general only one opening, which almost always takes its name from the principal river which flows into it. These lakes have often sources of their own, either near the borders, or in their bottom. The great lakes of North America are of this class, which in point of extent resemble seas, but which, by the flow of a continual stream of fresh river water, preserve their clearness and sweetness. The fourth class of lakes present phenomena much more difficult to explain. We mean those lakes which receive streams of water and often great rivers, without having any visible outlet. The most celebrated of these is the Caspian Sea; Asia contains a great many others besides. South America contains the Lake Titicaca, which has no efflux, though it is the receiver of another lake. These collections of water appear to belong to the interior of great continents; they are placed on elevated plains, which have no sensible declivity towards the sea, and thus afford no outlet. With respect to those situated in a hot climate, evaporation is sufficient to carry off their excess of water.

The physical phenomena which certain lakes present, have always excited the astonishment of the multitude. Those of the periodical lakes are the most common. In Europe these are nothing but pools, but between the tropics these pools sometimes cover spaces of several hundred leagues in length and breadth. Such are the famous lakes of Xarages and Paria, inscribed on maps of America, and expunged from them by turns; it is probable that Africa contains a great many of this description. The depth of lakes varies infinitely, and cannot form a subject of general physical geography. The popular opinion, however, that there are lakes without a bottom, is erroneous. Those which have been considered as such, owe this character solely to the existence of currents which carry along with them the lead attached to the sounding line. The waters of lakes, being derived from springs and rivers, partake of their different qualities. There are some lakes, whose waters are extremely limpid, such as the lake of Geneva, and that of Wetter in Sweden; in the latter, a farthing may be perceived at the bottom of the lake, at one hundred and twenty feet depth; but the lakes whose waters are motionless, saline, or bituminous, may be looked upon as equally unwholesome with those of marshes.
