Another expedition against Mexico was to sail from Cadiz on

the 8th of this month. It is now alleged that the principal cause of BARRADAS'S failure was the want of provisions ; and a Sefior Don EDMOND() MORAY, in order to prevent a similar catastrophe, has contracted to supply the present expedition with provisions-for twelve months. We have no doubt that its fate will be only delayed by this caution, for, of all possible undertakings, the reduction of its re- bellious provinces by the feeble and wasted resources of Spain seems the most utterly hopeless. Still, these attacks disturb what they can- not destroy ; and it therefore becomes a serious question, whether other powers, who are deeply interested in the tranquillity of the Western World, ought not to interli!re for the purpose of putting a stop to them. We interposed between Turkey and its colony of Greece, at a time when the latter, so far from having vindicated its freedom, was all but occupied by the troops of the Sultan ;—and why ?—Because the continuation of an exterminating war in tic Levant was destructive of our commerce there. All the piricies, however, that were perpetrated by the Greek mistics, were trifling com- pared with the damage which has arisen to our commerce from the fleets of privateers, and vessels pretending to be such, that have scoured ' the coasts of South America, and a large portion of the Atlantic, for years. Did our Turkey trade in its amount so much surpass our South American and Central American commerce, that a departure. from the ordinary rules of international law was justifiable in the one case and not justifiable in the other? We do not say to Government, "Go to war with Spain ;" but we say, taking the damage which our commerce suffers from these continued disputes—the impossibility of the New States fulfilling their engagements while they are per- mitted to continue—the real loss of income and property which they thus occasion, as well as the encouragement to crime which they hold out, a much stronger case of interference is afforded to England than any that existed when the celebrated treaty of the 6th of July was entered on.
