СКАЧАТЬ lake as it is a swollen river. If the Rhône is an artery, the lake is a sort of aneurism; there is a current from one end to the other which keeps it constantly changing. Then, owing to atmospheric conditions, at least twice a year (as in even the most stagnant ponds) the top layers sink to the bottom and the bottom layers come to the top. There is also a sort of tide or tidal fluxes, called seiches. The word means originally the flats exposed by low water, but is applied here to variations averaging ten inches or so in the level of the lake, but sometimes greatly exceeding that. There were three or four in one day in September, 1600, when the lake fell five feet and boats were stranded. De Saussure, one August day in 1763, measured a sudden fall of 1.47 meters, or four and a half feet, in ten minutes’ time. Eight years previously, the effect of the great earthquake which destroyed Lisbon was noticed in the vibration of the lake. Various explanations of this curious phenomenon have been given. One was that the Rhône was stopped and, as it were, piled up at the so-called Banc du Travers – a bar or shallow between Le Petit Lac and Le Grand Lac which begins on a line between La Pointe de Promenthoux on the north and La Pointe de Nernier in Savoy on the south. It is probably due to the sweeping force of the winds. When there is a heavy storm waves on the lake have been observed and measured not less than thirty-five meters long and a meter and seven tenths in height.

      James Fenimore Cooper in his novel “The Headsman of Berne,” published anonymously while he was United States Consul at Lyons, thus describes this wonderful body of water: – “The Lake of Geneva lies nearly in the form of a crescent, stretching from the southwest towards the northeast. Its northern or the Swiss shore is chiefly what is called, in the language of the country, a côte, or a declivity that admits of cultivation, and, with few exceptions, it has been, since the earliest periods of history, planted with the generous vine.

      “Here the Romans had many stations and posts, vestiges of which are still visible. The confusion and the mixture of interests that succeeded the fall of the Empire gave rise in the middle ages to various baronial castles, ecclesiastical towns and towers of defence which still stand on the margin of this beautiful sheet of water, or ornament the eminences a little inland… The shores of Savoy are composed with unmaterial exceptions of advanced spurs of the high Alps, among which towers Mont Blanc, like a sovereign seated in the midst of a brilliant court, the rocks frequently rising from the water’s edge in perpendicular masses. None of the lakes of this remarkable region possess a greater variety of scenery than that of Geneva, which changes from the smiling aspect of fertility and cultivation at its lower extremity to the sublimity of a savage and sublime nature at its upper.”

      It seems almost incredible, but Lausanne lies a good deal nearer to the North Pole than Boston does. The degree of latitude that sweeps across the lake where we started cuts just a little below Quebec, nearly touches Duluth and goes a bit south of Seattle. There are really three lakes, forming one which, in its whole extent, has a shore-line of one hundred and sixty-seven kilometers, the north shore being twenty-three longer than the south. Its greatest width is thirteen and eight-tenths kilometers, and it covers an area of about five hundred and eighty-two square kilometers. Its maximum depth is 309.7 meters. It is a true rock basin. The Upper Lake is, for the most part, a level plain, filled by the greyish-muddy Rhône which uses it as a sort of clearing-house. Being denser than the lake, the water of the river sinks and leaves on the bottom its perpetual deposits of mud, coarser near the shore, finer the farther out one goes. When the bottom of the Grand Lake is once reached, it is as flat as a billiard-table. Sixty meters from the Castle of Chillon it is sixty-four meters deep and shelves rapidly to three times that depth.

      Deep as it seems – for a thousand feet of perpendicular water is in itself a somewhat awesome thought – still, in proportion to its surface-extent, the lake is shallow. Pour out a tumbler of water on a wooden chair and the comparative depth is greater.

      Pure as it seems to be – and the beauty of its colour is a proof of it – the Rhône carries down from it to the sea a vast amount of organic matter and, as it drains a basin of eight thousand square kilometers, it is not strange that Geneva, which has used the lake-water for drinking purposes since 1715, has occasionally suffered from typhoid fever. In 1884 there were sixteen hundred and twenty-five cases; but, since the intake-pipes have been carried farther into deep water, the danger seems to have passed. Ancient writers supposed that the Rhône ran through Lake Leman without mixing its waters; they did not know that the lake is the Rhône.
