_Mr. William H. Dupree_, at one time the very efficient manager of the Union-Valley Brass Band, in which he was also a performer on the [B-flat]-baritone, is a gentleman whose history is such as to warrant particular mention here, not only on account of his having always possessed an ardent music-loving spirit, but also from his general intelligence, and the fine progress he has made in attaining to several high stations of honor and usefulness. Mr. Dupree remained a member of the band in Chillicothe until 1863, when, on the first call for colored troops for the late war, he went to Massachusetts, and enlisted in the Fifty-fifth Regiment. He became first sergeant of Company H; in which position he won golden opinions from those in command for his strict attention to duty, his steady and rapid acquirement of military knowledge (becoming one of the very best drill-masters and disciplinarians of his regiment), and for his generally fine, officer-like bearing. At one time Sergeant Dupree was manager of the regimental band, in which position he rendered important service. In 1864 he was promoted to the grade of a commissioned officer,--a rare distinction for one of his race, owing to causes so well understood that they need not be mentioned here. In this new place of honor he so discharged his duties as to prove the wisdom of those who tendered the appointment; for he was always distinguished for an increased display, if possible, of those excellent qualities, the possession of which caused his promotion. Mr. Dupree is now the very capable and popular superintendent of Station A Post Office in Boston, Mass. This office is situated in a district that comprises nearly forty thousand inhabitants, composed, for the greater part, of those among Boston's most intelligent and wealthy citizens. He was formerly connected with a musical organization in Boston. Although prevented by his other occupations from devoting much attention to music, Mr. Dupree has lost none of his old-time love for it; nor has he forgotten the pleasant days of yore when he was connected with the brass band at Chillicothe, of whose members he now speaks in terms of the most friendly regard.
