The handsome building that stands today as Oella Mill was the William J. Dickey & Sons Textile Mill, which had been built on the ashes of the old Union Manufacturing Company mill, at one time the largest cotton mill in America. Dickey & Sons survived fire and flood and the Great Depression, but it could not overcome the shift to synthetic fabrics in postwar America. The mill had shut down shortly before Agnes hit, and was never to open again. It would take the combined efforts of private developers and county, state, and federal agencies over several years to bring new vitality to picturesque Oella, a town that is a genuine piece of America's past.
Oella and nearby Ellicott City are the heart of the Patapsco River Valley, one of America's first and most important centers of industry. In the Revolutionary War and the War of 1812, the former colonies had declared their philosophical and political independence. To take its place as an equal among the nations of the world, however, the young country needed to establish its economic independence. Rather than simply being a supplier of raw materials to the Old World and a market for European products, America sought to nurture manufacturing of various kinds on its own soil. Close to the thriving port of Baltimore, the Patapsco River provided a convenient and reliable source of power to operate numerous foundries, iron mills, textile factories, and paper mills.
The entrepreneurial spirit that built Oella and neighboring towns also powered America's geographic and technological growth. From here, the Baltimore & Ohio railroad, the nation's first, linked the East Coast and the heartland. Today, the mills and factories that once defined this valley have all but disappeared. But many of the stalwart buildings remain, reminders of earlier chapters in the long story of these wooded hills—a story that continues into a bright tomorrow as people rediscover the enduring pleasures of living in a place like Oella.
