These references to assassination and death, were no casual flourishes of oratory. They were deliberate defiances of the fate which had already been denounced against the speaker, in public and in private, which continued to be threatened during all the rest of his life, and which finally actually befel him, but the fear of which never made him turn pale nor waver in his duty. He began as soon as he was nominated, to receive anonymous letters from the South threatening him with death. They became so frequent that he kept a separate file of them. They continued to come, up to the year of his death. The first one or two, he said, made him "a little uncomfortable;" but afterwards he only filed them. The train on which he left home for the East, was to have been thrown off the track. A hand grenade was hidden in one of the cars. An association was known to exist at Baltimore for the express purpose of killing him. When therefore he spoke as he did at Philadelphia, it was doubtless with a feeling that some one concerned in these plans was probably hearing him, and understanding him. It was, no doubt, at the same time a sort of vow, taken upon himself under the feelings aroused by the birth-place of the Declaration which he had so often and so well defended. Whether a challenge, a vow, or a mere statement of principle, he kept his word. He lived by it, and he died by it. The same mixture of firmness and kindness appears in the First Inaugural, and in this document there is also another most characteristic element;--circumspect adherence to the Constitution as he understood it, and most remarkable care and skill in the language used to interpret law, or to announce his own conclusions or purposes. Lover of freedom as he was, and believer in the rights of man, he had already been invariably careful not to demand from the masses of men whom he sought to influence, more than they could be expected to give. Now, he went even further. He expressly and clearly avowed his intention to execute all that he had sworn, even the laws most distasteful to any freeman. In speaking of the crisis of the moment, and after setting forth his doctrine of national sovereignty and an unbroken Union, he promised to maintain it as far as he could, and added: "Doing this I deem to be only a simple duty on my part; and I shall perform it so far as practicable, unless my rightful masters, the American people, shall withhold the requisite means, or in some authoritative manner direct the contrary." Then, as if to avert ill feeling if possible: "I trust this will not be regarded as a menace, but only as the declared purpose of the Union, that it will constitutionally defend and maintain itself." Then, with careful adherence to the mildest terms possible--could anything be a more peaceful assertion of national right than the simple "hold, occupy and possess"?--he says what the nation will do:
