We apprehend that a difference of thirty or forty per cent is sufficient to tempt the French corn-grower, or miller, into the higher-priced market which lies so conveniently open to him; and thus from the model republic of the Old, no less than from the model republic of the New World, must the English farmer expect to see for the future those supplies of grain and flour pouring in, which shall prevent his produce procuring a remunerating price. To complete the picture, it should not be forgotten that both these exporting countries impose considerable duties on the importation of grain and flour, and thus afford us a perfect specimen of that reciprocity which all Liberal governments and free nations were so anxious to establish, according to our sapient rulers, in 1846. We do not think that we need add any further argument to what has been already said. Our antagonists, the Free-traders, have been allowed--what they required and what was fair--time for the working of their experiment. Ample time has been granted, and we now see that it has failed in every particular. They said that it would induce reciprocity; it has induced higher opposing tariffs. They said it would secure for Great Britain the manufacturing custom of the world; on the contrary, foreign manufactories are springing up with unexampled rapidity. They said it would increase the demand for iron; it has prostrated it. They said it would give full employment to all our labouring population; it has displaced labour, and driven our working men by hundreds of thousands to emigrate. They said it could not attract such an importation of foreign grain and provisions, as permanently to beat down prices in this country below the remunerating level; it has already brought such an influx of these articles, that the grower of grain is impoverished, and the breeder of cattle ruined. They said it would be the commencement of a new era of prosperity to Ireland; it has laid it utterly desolate!
