Gallatin and Clay spent some time in Paris, and most of the ensuing summer in London on further negotiations of details. But Clay had no sooner returned to Lexington than he was re-elected to the national legislature, where he was again chosen Speaker, December 4, 1815, having declined the Russian mission, and the more tempting post of the Secretary of War. He justly felt that his arena was the House of Representatives, which, as well as the Senate, had a Republican majority. It was his mission to make speeches and pull political wires, and not perplex himself with the details of office, which required more executive ability and better business habits than he possessed, and which would seriously interfere with his social life. How could he play cards all night if he was obliged to be at his office at ten o'clock in the morning, day after day, superintending clerks, and doing work which to him was drudgery? Much more pleasant to him was it to preside over stormy debates, appoint important committees, write letters to friends, and occasionally address the House in Committee of the Whole, when his voice would sway the passions of his intelligent listeners; for he had the power "to move to pity, and excite to rage." Besides all this, there were questions to be discussed and settled by Congress, important to the public, and very interesting to politicians. The war had bequeathed a debt. To provide for its payment, taxes must be imposed. But all taxation is unpopular. The problem was, to make taxes as easy as possible. Should they be direct or indirect? Should they be imposed for a revenue only, or to stimulate and protect infant manufactures? The country was expanding; should there be national provision for internal improvements,--roads, canals, etc.? There were questions about the currency, about commerce, about the Indians, about education, about foreign relations, about the territories, which demanded the attention of Congress. The most important of these were those connected with revenues and tariffs. It was this latter question, connected with internal improvements and the sales of public lands, in which Clay was most interested, and which, more than any other, brought out and developed his genius. He is generally quoted as "the father of the protective policy," to develop American manufactures. The genius of Hamilton had been directed to the best way to raise a revenue for a new and impoverished country; that of Clay sought to secure independence of those foreign products which go so far to enrich nations. Webster, when reproached for his change of views respecting tariffs, is said to have coolly remarked that when he advocated the shipping interest he represented a great commercial city; and when he afterwards advocated tariffs, he spoke as the representative of a manufacturing State,--a sophistical reply which showed that he was more desirous of popularity with his constituents than of being the advocate of abstract truth.
