Highly injurious, however, as are the duties which are levied in the colony, they are not nearly so oppressive as those which are levied in this country, on spermaceti, right whale, and elephant oils procured in vessels built in the colony.  The duties on the importation of such oil into this country, are L24 18s. 9d. for the first sort, and L8 6s. 3d. for the two last.  If we add to these enormous duties those which are levied by the authority of the local government, it will be perceived that all the spermaceti oil procured by the colonial vessels has to pay a duty of L28 8s. 9d. and all the right whale and elephant oil a duty of L10 6s. 3d. before it can come into competition with the oil of the same description procured in vessels built in the united kingdom.  It has, however, been seen, that the colonists, propelled not less by that spirit of enterprize which distinguishes Englishmen in every quarter of the globe, than by the desire of finding profitable employment for that large portion of unoccupied labour, of which I have hastily pointed out the causes and march for the last fifteen years, have frequently attempted, notwithstanding these overwhelming prohibitions, to carry on these fisheries, but always without success; and that the valuable fishery of right whales which the river Derwent affords at a particular season, is now only resorted to, in order to procure the trifling supply of oil which is requisite for the East India market and for internal consumption.  All attempts to export oil to this country have been for many years abandoned; since the trade could only be maintained at a dead loss, as the ruinous experience of many of the colonial merchants has abundantly attested.  The reason why these enormous duties were imposed on oil procured in the colonial vessels is not generally understood here, but it is universally known in the colony; and the knowledge has materially tended to increase the dissatisfaction which the imposition of such duties would of itself, to a certain extent, have naturally excited.  The act which authorizes these duties, is one of those smuggled acts by which, to the disgrace of our legislature, the welfare and happiness of helpless unprotected thousands have been so frequently sacrificed on the shrine of individual avarice or ambition.  It originated in a certain great mercantile house extensively concerned in the South Sea fisheries, and could never have been passed, had there been a single person in either house of parliament, at all interested in the prosperity of this colony.  This act, indeed, is such a terrible deviation, such a monstrous exception to the usual policy of this country with respect to the fisheries, that it carries with itself the strongest internal evidence of its polluted origin.  No such restrictions had ever before been imposed on any of our colonies, as will be sufficiently evident, if we compare the duties which are levied in this country on oils procured in the vessels belonging to the colonies in North America and the West Indies, with those which are levied on oils procured in the vessels fitted out from the united kingdom.  These duties are as follow:
