Singular blindness! Mr. Buchanan lived for several years, as American ambassador, in England. It is to be presumed that while there he used his eyes, and possibly his brains. He must have noticed occasionally, at least, in his walks through "the city," the immense marble structure in Threadneedle Street, known as the Bank of England. It is certain that he has read the history of that bank, inasmuch as it is twice or thrice alluded to in his Message; he cannot be ignorant, therefore, that the "circulation" of England has essentially "a specie basis"; that no bank-notes are issued there for less than the amount of twenty-five dollars; that the banks at all times keep on hand "one dollar of gold for every three dollars of their circulation and deposits"; and that the laws of bankruptcy are alike rigid in regard to institutions and individuals. These are precisely the provisions which he commends to the adoption of wise and patriotic State legislatures as an admirable corrective for suspensions; yet he forgets to explain to us how it happens that the Bank of England, to which they are all applied, has virtually suspended payment six times in the course of its existence, having been saved from open dishonor only by the timely assistance of the government,--while the trade of England, in spite of the staid and conservative habits of the people, is quite as liable to those terrific tarantula-dances, called revulsions, as our own. Before urging his "restraints," the President ought to have inquired a little into the history of such restraints; and he would then have saved himself from the absurdity of patronizing remedies which an actual trial had proved ludicrously inapt and inefficacious. With regard to the second topic of the Message,--our foreign relations,--it may be said that the positions assumed are frank, manly, and explicit; unless we have reason to suspect, in the slightly belligerent attitude towards Spain, a return, on the part of the President, to one of his old and unlawful loves,--the acquisition of Cuba. In that case, we should deplore his language, and be inclined to doubt also the sincerity of his just denunciations of Walker's infamous schemes of piracy and brigandage. Until events, however, have developed the signs of a sinister policy of this sort, we must bestow an earnest plaudit upon his decided rebuke of the filibusters, coupling that praise with a wish that the "vigilance" of his subordinates may hereafter prove of a more wide-awake and energetic kind than has yet been manifested.
