An unwonted interest attaches to the assassination of Mr. Lincoln, not alone from the peculiarly dramatic incidents by which it was attended, but also from the controlling influence he would unquestionably have exerted, if his life had been spared, in modifying and facilitating the solution of perhaps the greatest social and political problem of modern times. This problem, after being committed to the solemn arbitrament of the sword, and passing through its ordeal, had now reached an ulterior stage of development which demanded, in the council chamber, the exercise of even higher administrative qualities than those which had hitherto directed its general conduct in the field. These attributes, it was generally recognized and conceded, were possessed by Mr. Lincoln in a pre-eminent degree. To a constancy of purpose and tenacity of will, of which conspicuous evidence had been presented in the final triumph of the Union cause, he united a conciliatory disposition, and the gentleness, sensibility, and simplicity of a child. Frequent reference has already been made to the humane and generous promptings of Mr. Lincoln's great soul, in all the varied relations of his life, as well private as official, and to instances of patriotism and of self-sacrifice almost unparalleled in the annals of history. With a more enlarged experience of the violence of party passion and of internecine strife, and of the excesses to which they sometimes unhappily lead, it seems almost incredible that the apprehensions of danger to Mr. Lincoln should have been shared by so few, when one thinks of the simplicity of his domestic habits, the facilities at all times afforded for a near approach to his presence, and the entire absence of all safeguards for the protection of his person, save the watchfulness of one or two of his most immediate friends; and this, too, at a period of such unprecedented party excitement and sectional strife and animosity. But the truth is, the crime of assassination was so abhorrent to the genius of Anglo-Saxon civilization, so foreign to the spirit and practice of our republican institutions, that little danger was apprehended of an outrage against society at large, the recollection of which even now suffices to tinge with a blush of shame the cheek of every true American, whether of Northern or of Southern birth.
