In consequence of that system, the importation of several sorts of goods has been prohibited altogether. This prohibition has, in some cases, entirely prevented, and in others has very much diminished, the importation of those commodities, by reducing the importers to the necessity of smuggling. It has entirely prevented the importation of foreign wollens; and it has very much diminished that of foreign silks and velvets, In both cases, it has entirely annihilated the revenue of customs which might have been levied upon such importation.
The high duties which have been imposed upon the importation of many different sorts of foreign goods in order to discourage their consumption in Great Britain, have, in many cases, served only to encourage smuggling, and, in all cases, have reduced the revenues of the customs below what more moderate duties would have afforded. The saying of Dr. Swift, that in the arithmetic of the customs, two and two, instead of making four, make sometimes only one, holds perfectly true with regard to such heavy duties, which never could have been imposed, had not the mercantile system taught us, in many cases, to employ taxation as an instrument, not of revenue, but of monopoly.
The bounties which are sometimes given upon the exportation of home produce and manufactures, and the drawbacks which are paid upon the re-exportation of the greater part of foreign goods, have given occasion to many frauds, and to a species of smuggling, more destructive of the public revenue than any other. In order to obtain the bounty or drawback, the goods, it is well known, are sometimes shipped, and sent to sea, but soon afterwards clandestinely re-landed in some other part of the country. The defalcation of the revenue of customs occasioned by bounties and drawbacks, of which a great part are obtained fraudulently, is very great. The gross produce of the customs, in the year which ended on the 5th of January 1755, amounted to £5,068,000. The bounties which were paid out of this revenue, though in that year there was no bounty upon corn, amounted to £167,806. The drawbacks which were
