The conferences and congresses which took place on the re-establishment of peace gave them great facilities for pressing their views on the different governments.
And Lord Liverpool's instructions to Lord Castlereagh and the Duke of Wellington, as plenipotentiaries of our government,[163] show the keen interest which he took in the matter, and the skilful manner in which he sought to avail himself of the predominant influence which the exertions and triumphs of this country had given her with every foreign cabinet.
Though Portugal was an ally to whom we regarded ourselves as bound by special ties, as well as by the great benefits we had conferred on her, yet, as she clung with the greatest pertinacity to the trade, he did not scruple to endeavor to put a constraint upon her which should compel her submission, and instructed Lord Castlereagh "to induce the Congress to take the best means in their power to enforce it by the adoption of a law, on the part of the several states, to exclude the colonial produce of those countries who should refuse to comply with this system of abolition." And exertions so resolutely put forward were so successful, that the trade was avowedly proscribed by every European nation, though unquestionably it was still carried on by stealth by merchants and ship-owners of more than one country--not, if the suspicions of our statesmen were well founded, without some connivance on the part of their governments.

Nor were our efforts in the cause the fitful display of impulsive excitement.

Individuals, as a rule, are slow to take warning from the experience of others; slower, perhaps, to follow their example in well-doing.

Nations are slower still.

When such an example is followed, still more when it is adopted by a general imitation, it will usually be found not only that the good is of a very unusual standard of excellence, but that he or they who have set the example are endowed with a force of character that predisposes others to submit to their influence.
