Mr. Kelley was at this time at the height of his power, and a more passionate and convinced supporter of the doctrine of protection has never sat in the Congress of the United States. He had not always been a protectionist. “In 1847,” he wrote once, “I had seen with gratification the protective tariff of 1842 succeeded by the revenue or free-trade tariff of 1846. To promote this change I had labored not only with zeal and industry, but with undoubting faith that experience would prove its benefits. For ten years all went well, and then came the panic of 1857.” To Mr. Kelley it was a knockout blow. He seems not to have considered the natural causes of the disturbance, but to have concluded the trouble lay entirely in the tariff, and for two years he went through the agony of a man losing his faith. Then in 1859 he sought Henry C. Carey for help. His conversion to protection was complete. As he himself said he came to regard the doctrine as an “exquisite harmony.” Everything which we could produce or manufacture should be so protected that the foreigner could not enter the market. By diversifying and expanding our industries we would draw greater and greater numbers to our country, thus giving larger and larger markets to our farmers. The manufacturers were to supply all the tools of the farmers and miners. Encouraged by prosperity production would multiply, and competition would reduce prices at home lower than abroad. It was a perfect circle. There is no doubt that the basis of Kelley’s devotion to protection was his belief that it was for the interest of the American working classes. The improvement of their condition was the passion of his life. Apprenticed as a boy to a Boston printer he had refused to be sent to college lest it might wean him from his class. He wanted to taste with them all the experiences of poverty—to know what it cost for a day laborer to live and rise in America. He had studied law at night, had sought the society of Channing and Emerson, had become a man of influence, but his motive had remained unchanged. The misery he saw in 1857 he charged entirely to the free-trade system. He could not rest until he had found a substitute. He believed he had found it in the “exquisite harmony” of protection. Having adopted a formula he believed competent to solve all problems, Kelley could support no criticism of its operations. Mr. Wells’s demonstration that high tariffs had not restored wool to its old vigor, had been the determining factor in building up the salt monopoly, that the iron men were getting the lion’s share of the duty on iron, that we could not build ships if we kept the price of materials so much higher than in other countries, was to him little better than blasphemy. Wells became his pet abomination—a detestation soon after extended to Professor Sumner of Yale, a man and an institution existing, he used to say angrily, for “the stupefaction of the youth of this country!”
