[ The modern philosophers of Sweden seem agreed that the waters of the Baltic gradually sink in a regular proportion, which they have ventured to estimate at half an inch every year. Twenty centuries ago the flat country of Scandinavia must have been covered by the sea; while the high lands rose above the waters, as so many islands of various forms and dimensions. Such, indeed, is the notion given us by Mela, Pliny, and Tacitus, of the vast countries round the Baltic. See in the Bibliotheque Raisonnee, tom. xl. and xlv. a large abstract of Dalin’s History of Sweden, composed in the Swedish language. * Note: Modern geologists have rejected this theory of the depression of the Baltic, as inconsistent with recent observation. The considerable changes which have taken place on its shores, Mr. Lyell, from actual observation now decidedly attributes to the regular and uniform elevation of the land.—Lyell’s Geology, b. ii. c. 17—M.]
Some ingenious writers [2] have suspected that Europe was much colder formerly than it is at present; and the most ancient descriptions of the climate of Germany tend exceedingly to confirm their theory. The general complaints of intense frost and eternal winter are perhaps little to be regarded, since we have no method of reducing to the accurate standard of the thermometer, the feelings, or the expressions, of an orator born in the happier regions of Greece or Asia. But I shall select two remarkable circumstances of a less equivocal nature. 1. The great rivers which covered the Roman provinces, the Rhine and the Danube, were frequently frozen over, and capable of supporting the most enormous weights. The barbarians, who often chose that severe season for their inroads, transported, without apprehension or danger, their numerous armies, their cavalry, and their heavy wagons, over a vast and solid bridge of ice. [3] Modern ages have not presented an instance of a like phenomenon. 2. The reindeer, that useful animal, from whom the savage of the North derives the best comforts of his dreary life, is of a constitution that supports, and even requires, the most intense cold. He is found on the rock of Spitzberg, within ten degrees of the Pole; he seems to delight in the snows of Lapland and Siberia: but at present he cannot subsist, much less multiply, in any country to the south of the Baltic. [4] In the time of Cæsar the reindeer, as well as the elk and the wild bull, was a native of the Hercynian forest, which then overshadowed a great part of Germany and Poland. [5] The modern improvements sufficiently explain the causes of the diminution of the cold. These immense woods have been gradually cleared, which intercepted from the earth the rays of the sun. [6] The morasses have been drained, and, in proportion as the soil has been cultivated, the air has become more temperate. Canada, at this day, is an exact picture of ancient Germany. Although situated in the same parallel with the finest provinces of France and England, that country experiences the most rigorous cold. The reindeer are very numerous, the ground is covered with deep and lasting snow, and the great river of St. Lawrence is regularly frozen, in a season when the waters of the Seine and the Thames are usually free from ice.

The fact is confirmed by a soldier and a philosopher, who had experienced the intense cold of Thrace. See Xenophon, Anabasis, l. vii. p. 560, edit. Hutchinson. Note: The Danube is constantly frozen over. At Pesth the bridge is usually taken up, and the traffic and communication between the two banks carried on over the ice. The Rhine is likewise in many parts passable at least two years out of five. Winter campaigns are so unusual, in modern warfare, that I recollect but one instance of an army crossing either river on the ice. In the thirty years’ war, (1635,) Jan van Werth, an Imperialist partisan, crossed the Rhine from Heidelberg on the ice with 5000 men, and surprised Spiers. Pichegru’s memorable campaign, (1794-5,) when the freezing of the Meuse and Waal opened Holland to his conquests, and his cavalry and artillery attacked the ships frozen in, on the Zuyder Zee, was in a winter of unprecedented severity.—M. 1845.]

[ Cæsar de Bell. Gallic. vi. 23, &c. The most inquisitive of the Germans were ignorant of its utmost limits, although some of them had travelled in it more than sixty days’ journey. * Note: The passage of Cæsar, “parvis renonum tegumentis utuntur,” is obscure, observes Luden, (Geschichte des Teutschen Volkes,) and insufficient to prove the reindeer to have existed in Germany. It is supported however, by a fragment of Sallust. Germani intectum rhenonibus corpus tegunt.—M. It has been suggested to me that Cæsar (as old Gesner supposed) meant the reindeer in the following description. Est bos cervi figura cujus a media fronte inter aures unum cornu existit, excelsius magisque directum (divaricatum, qu?) his quæ nobis nota sunt cornibus. At ejus summo, sicut palmæ, rami quam late diffunduntur. Bell. vi.—M. 1845.]
