If the revenue, however, which is at present raised by the different duties upon malt and malt liquors, were to be levied by a single duty upon malt, the opportunity of smuggling in the most important branch of the excise would be almost entirely taken away; and if the duties of customs, instead of being imposed upon almost all the different articles of importation, were confined to a few of the most general use and consumption, and if the levying of those duties were subjected to the excise laws, the opportunity of smuggling, though not so entirely taken away, would be very much diminished.
