HON. THOS. W. POWELL. Death of a Veteran Northwestern Ohio Pioneer. Special to the Cleveland Herald. Delaware, O., Dec. 12. At 7 o' clock this morning Hon. Thomas W. Powell died at his residence in the city at the advanced age of eighty five years. For several years he has been almost blind. His name stands foremost as one of the greatest thinkers of the State. The following history was given by Hon. James R. Hubble: Hon. Thomas W. Powell was born in South Wales in 1797. In 1801 he came with his parents to America and settled in Utica, N. Y. in the Mohawk Valley. During the war with Great Britain, although a mere youth, he drove his father's team with the baggage of a regiment, to Sackett's Harbor, and in the spring of 1813 entered the place at the close of the battle. In 1814 he was appointed by the military authorities to carry dispatches to Plattsburg, and at the close of that battle entered the town with dispatches to Gen. McCombs. In the year 1819 he came to Ohio and studied law in the office of Hon James W. Lathrop, at Canton, and in 1820 was admitted to the bar. He removed to Perrysburg, on the Maumee, where he filled successively the offices of Prosecuting Attorney and County Auditor of Wood county. In the discharge of his official duties, he was noted for his probity and industry as well as his abilities. In 1830 he removed to Delaware, where he has resided for a period of fifty years. He immediately commenced practice, and for a period of more than thirty years he was regarded by the profession in Delaware and throughout the counties in Central Ohio as a strong and successful lawyer. In special pleading and equity, to which he devoted particular attention, he excelled. His industry seemed untiring both in his profession and as a student. Law, history and literature received constant attention when not occupied with the cares and duties of his business and professional engagements. To his industry in his profession and in letters, Mr. Powell added great enterprise in all matters of interest to the public. He projected and prosecuted to completion the improvements at the Sulphur Springs known as the "Mansion House," which in its early history was famous as a fashionable resort, and which subsequently secured to Delaware the Ohio Wesleyan University. He built the flax mills at Delaware. He had an exquisite taste for the arts, horticulture and architecture especially, and his knowledge of those arts was of a high order. Mr. Powell although he took a lively interest in public affairs, was never a partisan. He was elected Representative and Senator in the State Legislature, and for many years was County Judge. He was given to the profession of his choice and to which be was an ornament, two works which were much needed and are highly prized by the courts and bar, viz: "Powell's Analysis of American Law,'' and a work on ''Appellate Jurisdiction." He has written two other books which are receiving the attention of the public, viz.: "History of the Ancient Britons," and "What is Knowledge?' the latter having been written within the last year. He leaves the following children to mourn his death: General Eugene Powell, Hon. S. E. Powell, Mrs. C. Staubaugh, Mr. Louis Powell and Miss Helen Powell.
