The classes who look at questions of policy with an eye to expediency are, the leading statesmen of both parties, who regard as the proper end of their labors the interests of Great Britain, and the business-community, who judge of every political event by the manner in which it affects their pockets. There are two other classes, who take a higher view,--those who are conservative and fearful of innovation, and those who believe in the progressive tendency of the Anglo-Saxon. Within the last quarter of a century, the public opinion of England has been undergoing a great change, especially that part of it which is influenced by the lower-middle class. The people have been growing up to the adoption of liberal principles of government. The Reform Bill of 1832 was a great stride in that direction; and the measures which have followed upon it have widened the observation of the masses, made the sense of political wrong quicker, and the appreciation of a free system much more vivid. As a natural result, the attention of this class has been drawn toward America, as the exponent of a government before which all men are equal,--and so it is, that, as the Rebellion goes on, we receive weekly evidence that the sober, honest thought of English opinion is with us of the North. The class to which we refer, if it is not now, will very shortly be, the governing element. The tendency is irresistibly that way; the signs of its growing power are daily more and more manifest. That it should be deeply interested in the perpetuity of American institutions, as affecting its own position, is natural. In the failure of man's self-governing capacity here, where every circumstance has been favorable to its exercise, the rising spirit of a broader liberty in England must foresee the death-blow to its own hopes. Our failure will not be fatal to us alone; it will involve the fate of the millions who are now seeking to plant themselves against the tremendous force of kingly and patrician prestige. They have hitherto derived from our example all the inspiration with which they have struggled upward. They have been able to accomplish, step by step, important alterations in the unwritten constitution, by the apt comparisons their leaders have been able to make between American and British civilization. So that, in considering the forces at work to influence those at the head of affairs, it is necessary to consider that force which is imperceptibly, but subtly, brought to bear upon them by the working-class. Mr. Beecher, and other eminent Americans who have lately visited England, tell us that this class are almost to a man sympathizers with us; and that this sympathy has in many cases worked favorably to us cannot be doubted. Even the operatives and manufacturers of Manchester and Leeds, at first, a little morose because of the effect of the war on their industry, seem to have come to a better second-thought, and are now outspoken for the North.
