It is a palpable falsehood to say we can have specie for our paper whenever demanded. Instead, then, of yielding to the cries of scarcity of medium set up by speculators, projectors and commercial gamblers, no endeavors should be spared to begin the work of reducing it by such gradual means as may give time to private fortunes to preserve their poise, and settle down with the subsiding medium; and that, for this purpose, the States should be urged to concede to the General Government, with a saving of chartered rights, the exclusive power of establishing banks of discount for paper.
