This is commonly called Mr. Webster's "Free Trade" speech. It has been found difficult to select one among his many speeches in support of the policy of Protection which would fully represent his views on the subject; but the reasons for his change of opinion, and for his advocacy of Protection, are fully stated in many of the speeches printed in this volume, delivered after the year 1830. Perhaps as good a statement as can be selected from his many speeches on the Tariff, in explanation of his change of position as to the need, policy, and duty of protection to American manufactures, may be found in his speech delivered in the Senate of the United States, on the 25th and 26th of July, 1846, on the Bill "To reduce the Duties on Imports, and for other Purposes." In this speech, he made the following frank avowal of the reasons which induced him to reconsider and reverse his original opinions on the subject:-- "But, Sir, before I proceed further with this part of the case, I will take notice of what appears, latterly, to be an attempt, by the republication of opinions and expressions, arguments and speeches of mine, at an earlier and later period of life, to found against me a charge of inconsistency, on this subject of the protective policy of the country. Mr. President, if it be an inconsistency to hold an opinion upon a subject at one time and in one state of circumstances, and to hold a different opinion upon the same subject at another time and in a different state of circumstances, I admit the charge. Nay, Sir, I will go further; and in regard to questions which, from their nature, do not depend upon circumstances for their true and just solution, I mean constitutional questions, if it be an inconsistency to hold an opinion to-day, even upon such a question, and on that same question to hold a different opinion a quarter of a century afterwards, upon a more comprehensive view of the whole subject, with a more thorough investigation into the original purposes and objects of that Constitution, and especially after a more thorough exposition of those objects and purposes by those who framed it, and have been trusted to administer it, I should not shrink even from that imputation. I hope I know more of the Constitution of my country than I did when I was twenty years old. I hope I have contemplated its great objects more broadly. I hope I have read with deeper interest the sentiments of the great men who framed it. I hope I have studied with more care the condition of the country when the convention assembled to form it. And yet I do not know that I have much to retract or to change on these points.
