The political principle of this revised ministry was the agreement of the centre of the _côté droit_, and the _droite_ itself, in one common vote; but the session under this management was long and troublesome, and a tedious and stormy debate took place before the Duke was able to decide upon the execution of his idea of an extended system of canal navigation, like that at present in force. He drew up a plan, inviting men possessed of large capital to take a part in these great works; for at that time the principal part of the capital in the kingdom, was invested in the funds, and enterprises tending to the benefit of industry and the improvement of the country were not popular: many difficulties were encountered, but they were all overcome by means of firmness and determination. Order was now established in all the departments of government; the restraints formerly imposed upon the action of the municipal authorities, by a system of excessive centralisation, were removed; and in the financial department the most unlimited competition was invited, for the first time, in the sale of stock, and the value of public securities reached its highest pitch. In his foreign policy, the Duke never ceased for a moment to support the idea of the Russian alliance, less from former recollections, and his affection for the Emperor Alexander, than upon the principle constantly expressed in all his correspondence, that the Russian alliance was advantageous to France because it was perfectly disinterested. In fact, what can Russia demand of us? On what point can we clash? Commerce with her can never be otherwise than an equal exchange; the productions of industry in her country are not of equal value with ours; she requires our wines, our fashions, our manufactures, and we, in exchange, require her timber, her copper, and her iron. Her fleets cannot assume any dominion over us, her frontiers do not reach us in any direction, and we are benefited by her influence; whilst, on the other hand, the designs and interests of France are opposed by the English alliance in all questions of importance. M. de Richelieu's system was resumed by M. de la Ferronays in 1828.
