Dr. W. T. Dinwiddie, a young man who is engaged in the practice of dentistry at Lexington, Ky., is a credit to the race. He is a native of Danville, Ky., where he attended the public schools of that city, afterwards taking a two years' course in the Knoxville College at Knoxville, Tenn. Dr. Dinwiddie first learned the carpenter's trade, and was regarded as a very fine workman; but, having a natural desire to practice dentistry, he decided to enter Meharry Medical and Dental College at Nashville, Tenn., and fit himself for the practice of that profession. After a three years' course he graduated with high honors, and was called by the President and Faculty of Meharry Dental College to accept a professorship; and he took the chair of Prosthetic Dentistry, which position he held with both success and honor, until he resigned to enter into the practice of his profession at Lexington, Ky., where he has by his most excellent workmanship and genial manners built up a very large practice. JAMES E. DIXON. [Illustration: J. E. DIXON.] Mr. James E. Dixon, of Providence, R. I., belongs to that class of men who are helpful to my book in enabling me to demonstrate that the colored people are entering all the professions and business walks of life in which white men enter and succeed. Mr. Dixon went to the North from Richmond, Va. Having lost both his parents at a very early age, it left him to look after himself, just at the time when a loving mother is most needed. What he has in the way of an education was obtained at New Bedford, Mass. But having a desire to travel, he accepted an offer to go to sea, which vocation he followed for a number of years, rounding the globe at least seven times, visiting one or more parts of every continent, inclusive of Australia, New Zealand and a number of Islands in both the Pacific and Atlantic Oceans. Finding it to his advantage, he hailed from an English port, and stuck to the English Merchant Service. He secured a mate's certificate, and worked himself up to a position as chief officer of one of the finest sailing ships under the English flag. But by an unfortunate accident in Calcutta, July 4, 1884, he lost his right arm. He then returned to New Bedford, Mass., and after a hard struggle against big odds, mastered telegraphy. The Western Union Telegraph Co., in recognition of his services in their main office, appointed him on June 11, 1889, as manager of their branch office at the Parker House, New Bedford, which place he held until he resigned June 3, 1893, to take charge of his present position at Signal Tower on the main line of the New York, New Haven and Hartford Rail Road, at Providence, R. I. Some idea of his work and responsibilities is given in this statement. In 1894, 34,284 trains passed this point, and the number is never under this. The operator has to know and report the exact condition of every train. In addition he has to give a signal to each train whether or not it is all right to go ahead.
