The excise laws, it appears, I believe, from experience, obstruct and embarrass the operations of the smuggler much more effectually than those of the customs.

我相信，从经验来看，消费税法比海关更能有效地阻碍走私者的活动并使他们难堪。

By confining the duties of customs to a few sorts of goods, and by levying those duties according to the excise laws, a much greater saving might probably be made in the annual expense of the customs.

通过将关税限制在几种商品上，并根据消费税法征收这些关税，可能会大大节省海关的年度开支。
