It was otherwise, however, in
the reign of Athelstan; for there is a famous law made by him, by which the
rank and privileges of a thane are conferred on every merchant, who had
made three voyages across the sea, with a vessel and cargo of his own. By
another law passed in this reign, the exportation of horses was forbidden.
From this period till the conquest, England was prevented from engaging in
commerce by the constant irruption of the Danes, and by the short duration
of their sovereignty after they had succeeded in obtaining it. There are,
however, even during this time, some notices on the subject; as appears
from the laws of Ethelred: by these, tolls were established on all boats
and vessels arriving at Billingsgate, according to their size. The men of
Rouen, who brought wine and large fish, and those from Flanders, Normandy,
and other parts of France, were obliged to shew their goods, and pay the
duties; but the emperor's men, who came with their ships, were more
favoured, though they were not exempt from duty.

About the year 861, a Scandinavian vessel, probably on its voyage to
Shetland or Orkney, discovered the Feroe islands.
