It is as an expounder of Public International Law that his name will be most widely cherished. In the progress of Christian civilization, many of the rules now sustained by learned subtilty or unquestioning submission, shaping the public concerns of nations, will pass away. The Institution of War, with its complex code, now sanctioned and legalized by nations, as a proper mode of adjusting their disputes, will yield to some less questionable arbitrament. But a profound interest must always attach to the writings of those great masters who have labored to explain, to advance, and to refine that system, which, though incomplete, has helped to keep the great Christian Commonwealth in the bonds of Peace. Among these Mr. Wheaton's place is conspicuous. His name is already inscribed on the same tablet with those of Grotius, Pufendorf, and Vattel. [239] Ovid, Epist. ex Ponto, Lib. IV. Ep. v. 43. It were wrong to close this imperfect tribute without a renewed testimony to the purity of his life. From youth to age his career was marked by integrity, temperance, frugality, modesty, industry. His quiet, unostentatious manners were fit companions of his virtues. His countenance, which is admirably preserved in the portrait by Healy, had the expression of thoughtfulness and repose. Nor station nor fame made him proud. He stood with serene simplicity in the presence of kings. In the social circle, when he spoke, all drew near to listen,--sure that what he said would be wise, tolerant, and kind. UNION AMONG MEN OF ALL PARTIES AGAINST THE SLAVE POWER AND THE EXTENSION OF SLAVERY. SPEECH BEFORE A MASS CONVENTION AT WORCESTER, JUNE 28, 1848. The effort to establish a political test in the Whig party in opposition to the extension of Slavery failed; but the Antislavery sentiment was constantly active. Those who coöperated in the movement were denounced as disturbers, and finally obtained an epithet, applied often in sarcasm, which may be considered their highest praise. They were called _Conscience_ Whigs, in contradistinction to _Cotton_ Whigs. The contest was continued in the newspapers, and also in the Legislature of Massachusetts. The course of the two great political parties compelled a final break. General Cass, who had abandoned the Wilmot Proviso, which he once maintained, was nominated by the Democrats as their candidate for the Presidency. General Taylor, who was a considerable slaveholder, was nominated by the Whigs, without any platform. It seemed impossible for persons earnest against Slavery to sustain either. Already, in New York, a considerable portion of the Democratic party, known as "Barn-burners," had refused to support General Cass, and nominated Martin Van Buren, adopting at the same time resolutions asserting the power of Congress to prohibit Slavery in the Territories, and calling for the exercise of this power.
