LONDON, March 22, 1775.--Conciliation as a means of allaying the present discontent in the American colonies was advocated in the House of Commons to-day by Mr. Edmund Burke. He proposed that Parliament abandon the idea of taxing the colonies, and instead place on the statute book an act acknowledging that the various colonial legislative bodies have the power to grant or refuse aids to the crown. Though his speech, which lasted over three hours, was heard with respect, the measures which he proposed were defeated by a strict party vote, 270 to 78. Mr. Burke spoke with a dignity and power which have not been surpassed even by the Earl of Chatham. His mastery of the subject was so complete and the form of his speech so perfect that competent judges pronounce it a classic. His speech is to be printed at once as a pamphlet. In outline Mr. Burke said: "As I have studied this American question for years, have held fixed opinions on it since 1766, and have nothing to gain except disgrace if I suggest a foolish solution of the problem, I believe that you will hear me with patience. My speech will consist of the discussion of two questions: (1) Should we attempt to conciliate the Americans? (2) If so, how? America is already powerful by virtue of population, commerce, and agriculture. The chief characteristic of the American people is their fierce love of freedom. There are only three ways to deal with this spirit: (1) To remove it by removing its causes; (2) to punish it as criminal; (3) to comply with it as necessary. Its causes are irremovable, being the love of independence which caused their ancestors to leave England; their religion in the North, which is the Protestantism of the Protestant religion; the fact that in the South they hold slaves; the general diffusion among them of education; the circumstance that they speak English and that an Englishman is the unfittest man on earth to argue another Englishman into being a slave; and the 3000 miles of ocean, between us and them. It cannot be treated as criminal, there being no way to draw up an indictment against a whole nation. Indeed, you have already tried to do this and failed. There remains no way of treating the American spirit except to comply with it as necessary. I propose, therefore, to erect a Temple of British Concord with six massive pillars by granting to America in six propositions the identical rights which for generations have been by acts of Parliament secured to Ireland, Wales, Chester, and Durham, except that, owing to the distance of America from England, each colony, instead of sending members to Parliament, shall have the power, through its own legislature, to grant or refuse aids to the Crown. If adopted, these measures, I believe,
