The Scandinavian countries are more interesting in respect to our present subject, on account of _their_ railway enterprises being wholly written in the future tense. Denmark has so little continuous land, Sweden has so many lakes, and Norway so many mountains, that, irrespective of other circumstances, railways have not yet reached those countries. They are about to do so, however. Hitherto, Denmark has received almost the whole of its foreign commodities _via_ the two Hanse towns--Hamburg and Bremen; and has exported its cattle and transmitted its mails by the same routes. The Schleswig-Holstein war has strengthened a wish long felt in Denmark to shake off this dependence; but good railways and good steam-ship ports will be necessary for this purpose. When, in April 1851, a steamer crossed rapidly from Lowestoft to Hjerting, and brought back a cargo of cattle, the Danes felt suddenly independent of the Hamburghers; but the route from Hjerting to Copenhagen is so bad and tiresome, that much must yet be done before a commercial transit can really be established. There was at that time only an open basket-wagon on the route; there has since been established a diligence; but a railway will be the only effective means of transit. Here we must correct a mistake in the last paper: Denmark is not quite without railway accommodation; there is about 15 miles of railway from Copenhagen to Roeskilde, and this is to be continued across the island of Zealand to Korsoer. The Lowestoft project has led to important plans; for a railway has been marked out from Hamburg, through the entire length of Holstein and Schleswig to the north of Juetland, where five hours' steaming will give access to the Swedish coast; while an east and west line from Hjerting to Copenhagen, with two breaks at the Little Belt and the Great Belt, are also planned. If Denmark can by degrees raise the requisite capital, both of these trunk-lines will probably be constructed. Norway has just commenced its railway enterprises. It seems strange to find the familiar names of Stephenson and Bidder, Peto and Brassey, connected with first-stone layings, and health-drinkings, &c., in remote Norway; but this is one among many proofs of the ubiquity of English capital and enterprise. The government of Norway has conceded the line to an English company, by whom it will be finished in 1854. The railway will be 50 miles in length; it will extend from Christiania to Lake Mioesen, and will connect the capital with an extensive chain of internal navigation. The whole risk seems to have been undertaken by the English company; but the benefits will be mutual for both companies--direct steam-communication from Christiania to some English port being one feature in the comprehensive scheme.
