RICHMOND, February 12, 1852. GENTLEMEN:— On my arrival in this city last evening I received your very kind letter, welcoming me to the metropolis of the Old Dominion and tendering me the honor of a public dinner. I regret—deeply regret—that my visit to Richmond will necessarily be so brief that I cannot enjoy the pleasure and the privilege of meeting you all at the festive board. Intending merely to pass a day with my valued friend, Judge Mason, my previous arrangements are of such a character that I must leave here to-morrow, or, at the latest, on Saturday morning. But whilst I cannot accept the dinner, I shall ever esteem the invitation from so many of Virginia’s most distinguished and estimable sons as one of the proudest honors of my life. Your ancient and renowned commonwealth has ever been the peculiar guardian of State rights and the firm supporter of constitutional liberty, of law, and of order. When, therefore, she endorses with her approbation any of my poor efforts to serve the country, her commendation is a sure guarantee that these have been devoted to a righteous cause. You are pleased to refer in favorable terms to my recent conduct “at home in defence of the Federal Constitution and laws.” This was an easy and agreeable task, because the people of Pennsylvania have ever been as loyal and faithful to the Constitution, the Union, the rights of the sovereign States of which it is composed, as the people of the ancient Dominion themselves. To have pursued a different course in my native State would therefore, have been to resist the strong current of enlightened public opinion.
