Some share—fluctuating and uncertain, but assuredly significant—of English foreign trade in modern times is to be credited to smugglers, who were ever busy in evading customs regulations and prohibitions. Mere administrative watchfulness and thoroughness could never do more than damp their activities; it was only the triumph of free trade in the early Victorian age that deprived them of their livelihood, and until then they were able to match by increase of cunning and of organization the ever more elaborate network of the customs system—its spies, its coastguards and its cutters as well as its routine officials at the ports. The smuggler flourished right down to the end of the period of protection, despite sporadic seizures by the revenue officers. In the first half of the nineteenth century, French wines, brandies and luxury textiles were being punctually shipped across the Channel in the teeth of prohibitions. In the other direction, we know, for instance, of the existence in the same period of so remarkable á phenomenon as the muslin manufacture of Tarare, near Lyons, which relied for its raw material upon the assured supply of English yarn owled abroad. But it was probably the eighteenth century, when customs regulations were at their most burdensome and complicated, that marked the classic epoch of illicit trade, the period in which the technical skill of both breakers and defenders of the law might earn the highest rewards.
