A railway runs south to Gjedser (14 m.), from which the sea-passage (29 m.) to Warnemiinde links the fastest route between Copenhagen and Berlin.
At that time fishing, whaling and shipbuilding were its principal industries, the clipper ships built here being among the fastest and best known on the seas.
Nevertheless along the whole line some kind of surveillance was established long before the close of 1861, and, in proportion as the number of vessels available increased, the blockade became more and more stringent, until at last it was practically unbreakable at any point save by the fastest steamers working under unusually favourable conditions of wind and weather.
One of the fastest runs is from Rome to Orte, 52-40 m.
An effort to encourage the development of the mercantile marine was made in the same year, and a convention was concluded with the chief lines of passenger steamers to retain their fastest vessels as auxiliaries to the fleet in case of war.
On the continent of Europe there are occasionally four classes, but though the local fares are often appreciably lower than in Great Britain, only first and second class, sometimes only first class, passengers are admitted to the fastest trains, for which in addition a considerable extra fare is often required.
A study of the family names appearing on the census rolls of two prosperous and typical American counties, one distinctively urban and the other rural, in 1790 and I900, has confirmed the popular impression that the British element is growing little, and that the fastest reproducers to-day are the foreign elements that have become large in the immigration current in very recent decades.
