In a Letter of mine, which you inserted in your
    Paper of Nov. 3, was contained a view of the state of our commerce
    with the American continent colonies. I now send you a view of our
    commerce with the West India or Sugar Islands, taken, as the former
    was, from the Custom House accounts. When your Readers have
    compared and considered these accounts, they may form a judgment
    which of those two classes of colonies is most beneficial to the
    mother country. I am Sir, your humble servant,
   
  
    which is £2,281,509 12s. 8d. per ann. on a medium
    of said 5 years,
   
  
    which is £785,545 2s. 4d. per ann. on a medium of
    said 5 years.
    Upon the face of these Custom House accounts it
    appears, that there is a balance against Great Britain of
    £1,495,954 10s. 4d. per annum, and by the same
    accounts that the balance against her annually increases. But to
    reduce this balance, which appears upon this comparative view of
    direct exports and imports, let us suppose, as we did in the case
    of the Northern colonies, that the errors of entry and of valuation
    will admit of one third more to be added to the amount of the
    export, though by no means just even for a comparative view of the
    value of the two setts of colonies to Great Britain; for not above
    one fourth of the exports to the Northern colonies is in foreign
    European and Asiatic goods, but to the West India Islands two
    thirds of the amount of the exports is in foreign goods; therefore,
    there is not that latitude for erroneous entries, as there is to
    the continent, it being impossible to make wrong entries for goods
    entitled to a drawback as all those of foreigners are.
    Then with the additional value to the imports
    mentioned under the account thereof, and the additional value to
    the exports just stated, the account will stand thus:
   
  
    But out of this balance must be struck what the Sugar Planters
    pay the Irish for provisions, and the British Merchants for slaves.
    As to the Irish provisions, the islands take but a small part of
    their consumption from them; they being chiefly supplied from North
    America, not only with provisions, but many other things, whom they
    pay in their products, that those Northern colonies consume. The
    very rum that goes directly from the Islands to Ireland, yields as
    much as the provisions they take from thence amounts to: And as to
    what they pay the British Merchant for slaves, it is almost
    impossible to fix with precision upon any amount, from the very
    nature of the trade on the coast of Africa; but to allow that the
    annual cost of Negroes is equal to the whole annual export from
    Great Britain to Africa, we shall not be impeached for being under
    the mark at least, when it is considered that part of the produce
    of that export is returned in gold dust, dying woods, and elephants
    teeth to Great Britain; part of its goes to supply foreign
    plantations with Negroes; and part of it goes in slaves to the
    continent colonies from Pensylvania to Florida, where a stock of
    70,000 Negroes is to be kept up in proportion to that of 250,000 in
    the sugar colonies. Now the whole export of Africa per ann. upon a
    medium of the above five years, is £433,529 17s. 8d.
    which deducted from the above balance of £2,375,204 5s.
    11d. leaves still an annual balance against Great Britain of
    £1,941,674 8s. 3d. while the poor Northern colonies
    have a balance in favour of G. Britain of £1,000,000 which all
    their other trade cannot pay, they being constantly in debt to G.
    Britain; when these Sugar Islands would be worth little to their
    owners, in comparison of what they are now, if it was not for cheap
    and ready supplies from the Northern colonies, of lumber for the
    building their houses, sugar mills, casks to contain their produce,
    horses, provisions of the cheapest kind for feeding their slaves in
    particular, and ships to bring home their produce at the cheapest
    rate known.
