How much of this surplus produce may be expected to find its way into the English market, we do not pretend accurately to foretell; but when we find that, without the inducement of an unrestricted access to it, in 1846 America was able to raise her exports of grain to thirteen millions of bushels, from six millions in 1845; and in 1847, with only the preparation of a year, to twenty-six millions, we think Lord Fitzwilliam is quite justified in taking it for granted that the price of corn in England will not rise above its present ruinous average. Attempts, no doubt, will be made to show that the emigration to California has deprived the Western States of the labour that is required to raise these enormous crops. Our answer is, that 300,000 souls were added by immigration to the population of the United States in 1849; and that our own emigration returns for 1850 show that the tide from England is flowing in that direction with unabated force. So last year, when the great and unexpected import of French flour was adding to the depression, and stimulating the complaints of the English agriculturists, the Free Import authorities explained it away as a forced unnatural importation which must speedily cease, as France was an importing, and not an exporting, county, and the price of corn there was naturally higher than in England; and yet we learn from the same organ of public opinion which favoured us in the summer with this satisfactory explanation of the French importations, that in the month of November last, the prices of wheat, flour, and bread were all much higher in London than in Paris. In its City article of November 14th, appeared the following comparison of the present prices of wheat, flour, and bread, in London and Paris:-- "The highest price of wheat of the first quality in Paris is 24 francs per 1-1/2 hectolitres, which is equal to 36s. 8d. per quarter; and the highest price of white wheat of the first quality, in London, being 48s. per quarter, it follows that wheat is 30-7/8 per cent dearer in London than in Paris. The highest quotation of flour of the first quality in Paris is 29 francs 95 cents the 100 kilogrammes, which is equal to 29s. 11d. per sack of 280 lb. English; and the highest quotation of flour in the London market being 40s. per sack, it follows that flour is about 33-5/8 per cent dearer in London than in Paris. The price of bread of the first quality in Paris is 27 cents per kilogramme, which is equal to 4-5/8 per 4 lb. loaf English weight; and the price of bread in London, at the full-priced shops, being 6-1/2d. per 4 lb., it follows that bread is 40-1/2 per cent dearer in London than in Paris."
