He insisted that by an adequate protection of domestic manufactures, there would be an increased demand for our raw materials at home, and thus the several productive and manufacturing sections of the Republic would realize the benefits of a dependence on each other, and the Union would be consolidated and perpetuated for ages to come.
While a candidate for the presidency, Mr.Adams received a letter inquiring his views on the subject of internal improvement.

The following is an extract from his reply:-- "On the 23rd of Feb., 1807, I offered, in the Senate of the United States, of which I was then a member, the first resolution, as I believe, that ever was presented to Congress, contemplating a general system of internal improvement.

I thought that Congress possessed the power of appropriating money to such improvement, and of authorizing the works necessary for making it--subject always to the territorial rights of the several States in or through which the improvement is to be made, to be secured by the consent of their Legislatures, and to proprietary rights of individuals, to be purchased or indemnified.

I still hold the same opinions; and, although highly respecting the purity of intention of those who object, on constitutional grounds, to the exercise of this power, it is with heartfelt satisfaction that I perceive those objections gradually yielding to the paramount influence of the general welfare.

Already have appropriations of money to great objects of internal improvement been freely made; and I hope we shall both live to see the day, when the only question of our statesmen and patriots, concerning the authority of Congress to improve, by public works essentially beneficent, and beyond the means of less than national resources, the condition of our common country, will be how it ever could have been doubted." On another occasion, Mr.Adams expressed himself on the subject of internal improvements in the following manner:-- "The question of the power of Congress to authorize the making of internal improvements, is, in other words, a question whether the people of this Union, in forming their common social compact, as avowedly for the purpose of promoting their general welfare, have performed their work in a manner so ineffably stupid as to deny themselves the means of bettering their own condition.
