Never in the range of human possibilities had a Cameron believed in an Adams--or an Adams in a Cameron--but they had curiously enough, almost always worked together. The Camerons had what the Adamses thought the political vice of reaching their objects without much regard to their methods. The loftiest virtue of the Pennsylvania machine had never been its scrupulous purity or sparkling professions. The machine worked by coarse means on coarse interests, but its practical success had been the most curious subject of study in American history. When one summed up the results of Pennsylvanian influence, one inclined to think that Pennsylvania set up the Government in 1789; saved it in 1861; created the American system; developed its iron and coal power; and invented its great railways. Following up the same line, in his studies of American character, Adams reached the result--to him altogether paradoxical--that Cameron's qualities and defects united in equal share to make him the most useful member of the Senate. In the interest of studying, at last, a perfect and favorable specimen of this American type which had so persistently suppressed his own, Adams was slow to notice that Cameron strongly influenced him, but he could not see a trace of any influence which he exercised on Cameron. Not an opinion or a view of his on any subject was ever reflected back on him from Cameron's mind; not even an expression or a fact. Yet the difference in age was trifling, and in education slight. On the other hand, Cameron made deep impression on Adams, and in nothing so much as on the great subject of discussion that year--the question of silver.
