D. L. Child, of the INational A. S. Standard thus describes this colebrated sjaveholder: At his house I saw Mr. McDuffie, then considered the flower of the Carolina delegation. He was said to be a protege of Mr. Calhoun, and his portrait occupied a place on the opposite wall. Mr. McDuffie possessed much acuteness and vigor, but I was never able to see in him or his friend, any ofthose decided marks of transcendant intellectual endowments vvhich would put them in the rank of first men. Randolph was said to view Mr. McDuffie with jeolousy upon his first appearance in the House. He was very soon a-tilting at him, and they closed Ãn mortal combat. Randolph's eyes were small, and as black as a snake's Ã¡nd they flashed on this occasion, with peculiar malignity. It was thought that he had rather the worst of it. One thing on McDuffie's part was unjustifiable and ungentlemanly. He hinted at physical peculiarities cause obliquity of the understandmg. I should cali Mr. McDuffie a smart rather than a great man. He was under an engagement to fight a Col. Cummings,oÃ jreorgia, anÃº was keeping the affair suspended, under pretence of duty to his constituents. This seemed to me to be affectation, and a sort of ostentation of that which Southern young men deern their gbry, though it is in reality their shame. But a great change is working, nay, is already wrought, in this respect. A few years ago a great barbecue was given to a gentleman in South Carolina for having refused to fight. This is coming upon New England. Mr. Cook for merly of Boston, now of New York, was publicly complimented, in one of the most respectable assemblages in Faneuil Hall, for declining a duel with a Mr. Burrell. The Honorable John Phillips, one of the favorite sons of the Bay State, gave at the table as a toast, the name of Cook and this sentiment: - "He shows his heroism by maintaining the laws of his country, not by the murder of his countrymen." Last winter I saw Mr. McDufRe totter into the Senate chamber, the merest wreek and skeleton of one of the most active, compact, and vigorous men. All accounts that I could hear, concurred in representing that he isracked with pains occasioned by one of Cummings' bullcts, lodged in the spine; that he has no expectation of living but a short time, and was 'waiting for death.' He is not above fifty-five and has the decreptitude of fourscore and ten. His mind is still bright and he made a keen and vigorous attack upon the Oregon ocdupation bill, brought forvvard by the late Dr. Linn."
