Clay was anxious for the position, but would do nothing unworthy to obtain it. He wrote to a friend, "On one resolution, my friends may rest assured, I will firmly rely, and that is, to participate in no intrigue, to enter into no arrangements, to make no promises or pledges; but that, whether I am elected or not, I will have nothing to reproach myself with. If elected, I will go into the office with a pure conscience, to promote with my utmost exertions the common good of our country, and free to select the most able and faithful public servants. If not elected, acquiescing most cheerfully in the better selection which will thus have been made, I will at least have the satisfaction of preserving my honor unsullied and my heart uncorrupted."
After the vote had been taken, as no candidate received a clear majority, the election necessarily went to the House of Representatives. Though Jackson received the most electoral votes, Clay, not friendly to him, used his influence for Adams and helped obtain his election. Clay was, of course, bitterly censured by the followers of Jackson, and when Adams made him Secretary of State the cry of "bargain and sale" was heard throughout the country. Though both Adams and Clay denied any promise between them, the Jackson men believed, or professed to believe it, and helped in later years to spoil his presidential success. Adams said, "As to my motives for tendering him the Department of State when I did, let the man who questions them come forward. Let him look around among the statesmen and legislators of the nation and of that day. Let him then select and name the man whom, by his preëminent talents, by his splendid services, by his ardent patriotism, by his all-embracing public spirit, by his fervid eloquence in behalf of the rights and liberties of mankind, by his long experience in the affairs of the Union, foreign and domestic, a President of the United States, intent only upon the honor and welfare of his country, ought to have preferred to Henry Clay."
Returning to Kentucky before taking the position of Secretary of State, his journey thither was one constant ovation. Public dinners were given him in Virginia, Pennsylvania, and Ohio. In the midst of this prosperity, sorrow laid her hand heavily upon the great man's heart. His children were his idols. They obeyed him because they loved him and were proud of him. Lucretia, named for her mother, a delicate and much beloved daughter, died at fourteen. Eliza, a most attractive girl, with her father's magnetic manners, died on their journey to Washington. A few days after her death, another daughter, Susan Hart, then Mrs. Durolde of New Orleans, died, at the age of twenty.
There was work to be done for the country, and Mr. Clay tried to put away his sorrow that he might do his duty. As Secretary of State he helped to negotiate treaties with Prussia, Denmark, Austria, Russia, and other nations. The opposition to Adams and Clay became intense. The Jackson party felt itself defrauded. John Randolph of Virginia was an outspoken enemy, closing a scathing speech with the words, "by the coalition of Blifil and Black George—by the combination, unheard of till then, of the Puritan with the blackleg."
Clay was indignant, and sent Randolph a challenge, which he accepted. On the night before the duel, Randolph told a friend that he had determined not to return Clay's fire. "Nothing," he said, "shall induce me to harm a hair of his head. I will not make his wife a widow and his children orphans. Their tears would be shed over his grave; but when the sod of Virginia rests on my bosom, there is not in this wide world one individual to pay this tribute upon mine."
The two men met on the banks of the Potomac, near sunset. Clay fired and missed his adversary, while Randolph discharged his pistol in the air. As soon as Clay perceived this he came forward and exclaimed, "I trust in God, my dear sir, that you are unhurt; after what has occurred, I would not have harmed you for a thousand worlds." Years afterward, a short time before Randolph's death, as he was on his way to Philadelphia, he stopped in Washington, and was carried into the Senate chamber during its all-night session. Clay was speaking. "Hold me up," he said to his attendants; "I have come to hear that voice."
At the presidential election of 1828 Andrew Jackson was the successful candidate, and Clay retired to his Ashland farm, where he took especial delight in his fine horses, cattle, and sheep. But he was soon returned to the Senate by his devoted State.
The tariff question was now absorbing the public mind. The South, under Calhoun's leadership, had been opposed to protection, which they believed aided northern manufacturers at the expense of southern agriculturists. When the tariff bill of 1832 was passed, and South Carolina talked of nullification and secession, Clay said: "The great principle which lies at the foundation of all free government is that the majority must govern, from which there can be no appeal but the sword. That majority ought to govern wisely, equitably, moderately, and constitutionally; but govern it must, subject only to that terrible appeal. If ever one or several States, being a minority, can, by menacing a dissolution of the Union, succeed in forcing an abandonment of great measures deemed essential to the interests and prosperity of the whole, the Union from that moment is practically gone. It may linger on in form and name, but its vital spirit has fled forever."
South Carolina passed her nullification ordinance, and prepared to resist the collection of revenues at Charleston. Then Jackson, with his undaunted courage and indomitable will, ordered a body of troops to South Carolina, and threatened to hang Calhoun and his nullifiers as "high as Haman."
Then the "great pacificator" came forward to heal the wounds between North and South, and preserve the Union. He prepared his "Compromise Bill," which provided for a gradual reduction of duties till the year 1842, when twenty per cent. at a home valuation should become the rate on dutiable goods. He spent much time and thought on this bill, visiting the great manufacturers of the country, and urging them to accede for the sake of peace.
