We have thus shown, we hope clearly enough, the dependence of revenue upon produce; a very important point, but one which is apt to be lost sight of in consequence of our complicated arrangements. People used to talk magniloquently, and in high-sounding terms, about taxed corn, and we have had ditties innumerable to the same effect, more or less barbarous, from Ebenezer Elliott and his compeers; but neither orator nor poetaster ever condescended to remark that the sole reason why duties were levied on the importation of foreign grain, was the existence of other duties to an enormous extent, directly and indirectly levied by Government from the British grower. Relieve the latter of these burdens, and he does not fear the competition of the world. But so long as you tax him who is, on the one hand, your largest producer, and, on the other, the best customer for your manufactures, you cannot, in reason, wonder if he demands that an equivalent for his taxation shall be imposed upon foreign produce; so that the economical law, and not less the law of common sense, which provides that the consumer shall pay all charges, may not be defeated--in other words, that his trade may not be annihilated altogether. We have seen articles, intended to be pungent and satirical, about the farmers "whining for protection." The writers who use such language evidently intend to insinuate that the British agriculturist is a poor weak creature, unable to cope with foreign tillers of the soil--more ignorant than the Dane, more idle than the German, less active than the Polish serf, and not near so handy as the American squatter. If they do not mean this, they mean nothing. It is not worth while replying directly to such paltry and contemptible libels, but we may as well remind these gentlemen with whom the "whining" commenced. It began with the manufacturers, who have been whining for heaven knows how many years, that bread was too dear, and that they were forced to pay high wages in consequence. The papermakers are "whining" at this moment for a reduction of excise, and the nasal notes of a good many newspaper editors and conductors of cheap and trashy periodicals are adding power and pathos to the whine. No spaniel at the outside of a street-door ever whined more piteously than Mr Cardwell is doing at this hour about reduction of the tea duties. He is absolutely not safe over a cup of ordinary hyson. There are whines about hops, whines about sugar, whines about window taxes, whines about cotton, and all Ireland is and has been in a state of perpetual whine. In short, if by "whining" is meant a complaint against taxation, we apprehend it would be difficult to find a single individual who, in the present anomalous and jumbled state of finance, could not advance sufficient reasons for uttering a cry. The only way to remedy this is to reconstruct the whole system. Let this be done on principles clear and intelligible to all
