At the opening of the session the Prince Regent had congratulated the country upon the prosperity of the revenue and of all branches of trade and manufacture.[719] As a matter of fact both the commercial and agricultural interests of the country were in a very bad way. The high prices produced during the latter part of the war by the continental system, which virtually excluded foreign competition, had been most disastrous to agriculture by encouraging a bad system of farming, whilst they inflicted the greatest hardship upon all but the wealthiest class. In 1811 the price of a quartern loaf--as set from time to time by the Court of Aldermen, according to the custom of the city,[720] "within the city and the liberties thereof, and the weekly Bills of mortality, and within ten miles of the Royal Exchange"--had risen to such a height that the Common Council presented an address to the Regent (18 Dec.) praying him to take measures for re-opening commercial intercourse with foreign, and especially neutral, nations. To this the Regent replied that nothing should be wanting on his part towards restoring commercial intercourse between this country and other nations "to the footing on which it has been usually conducted, even in the midst of war."[721] The average price of the quartern loaf, from this period until the autumn of 1813, when the country was blessed with a rich harvest, may be set down at 1_s._ 6_d._ It then began to fall rapidly. Flour, however, kept up in price for some time owing to the dryness of the summer, which prevented many mills near London from working, whilst several of the mills which could work "were engaged in answering the demands of government for the army abroad, and the prisoners of war confined in this country."[722] [Sidenote: The City and the first Corn Law, March, 1815.]
