Pitt was highly satisfied with Lord Castlereagh's speech for the Union; he was summoned by the ministerial party to the united House of Commons, and appointed president of the Board of Control for the affairs of India. This is one of the appointments conferred in England by the ministers upon the talented men with whom they surround themselves, for the sake of their support in parliament. No man could be better acquainted with the situation of Ireland than Lord Castlereagh, or more perfectly aware of all the resources of the Orange party which could be employed for the purpose of repression. This knowledge rendered him a person of great importance, for the prime minister was then anxious to put into execution the union between England and Ireland, which had been decided upon in parliament, and Lord Castlereagh, who by his profound acquaintance with the moral topography of Ireland was the man most calculated to realise this design, was consulted upon all the measures to be pursued. Mr. Pitt especially possessed the practical genius which enabled him to discover men of particular capacity, and around him were a multitude of young and clever men, each with his appointed station and employment. The system of under-secretaries of state in England produces wonderful results; it gives to affairs their full developement, enabling the statesman to confine himself to generalities, both of ideas and systems, while the young under-secretaries devote all their energies to the statistics of detail and the internal administration. Thus was Lord Castlereagh situated; a man of an inflexible and laborious disposition, who never arrived at a general idea except by means of the most careful and minute study of all the circumstances. This special knowledge of affairs caused Lord Castlereagh to be retained even during Mr. Addington's ministry, which lasted but a very short time, and was succeeded by Mr. Pitt's still more decided plans against the French revolution. Addington signed the peace of Amiens, and Castlereagh, as president of the Board of Trade, had to deliberate upon all the measures which augmented the commercial relations of England with India and the colonies. He assumed no position as a political character, for he did not agree with the ideas entertained by Addington, and he, therefore, completely gave himself up to his duties at the Board of Control and to the affairs of Ireland. His heart was full of detestation for France, and, in imitation of his master, he allowed this administration to pass without taking any part in it. As a reward for his conduct on this occasion, Pitt, on resuming his situation at the head of affairs, gave him the portfolio of the War department.
