Belgium--a kind of little England--has for a number of years been well provided with railways; and you may go by locomotion towards its frontiers in all directions, except one--namely, that of Holland. This odd exception, of course, arose from the ill-will that has subsisted for a number of years between the Belgians and Dutch; the latter being not at all pleased with the violent disjunction of the Netherlands. However, that coolness is now passing off. The two neighbours begin to find that ill-nature does not pay, and, like sensible people, are negotiating for a physical union by rail, seeing that a political one is out of the question. In short, a railway is proposed to be laid down in an easterly direction from the Antwerp branch, towards the border of Holland; and by means of steam-boat ferries across the Maas and other mouths of the Rhine, the junction will be effected with the Rotterdam and Amsterdam series of railways. The north of Holland is yet a stranger to railways, nor are the towns of such importance as to lead us to expect any great doings there. But the north German region--from the frontiers of Holland to those of Russia and Poland, a distance of something like 1000 miles--is rapidly filling up the chasms in its railway net-work. Emden and Osnaburg and Gottingen in the west, Danzig and Koenigsberg and Memel in the east, are yet unprovided; but almost all the other towns of any note in Prussia and North Germany are now linked together, and most or all of the above six will be so in a few years.
