Bluffton is located on the Wabash River about twenty-five miles south of Fort Wayne and is served by two railroads. Its important industrial interests are foundries, stone quarrying, planing and tile mills, and factories for manufacture of pianos and hardwood flooring.

Bluffton is the home of Charles C. Deam, one of the nation's outstanding research foresters and botanists. In 1904, L. A. and C. B. Williamson planted the tree, which is known as the Deam Oak. The tree is located three miles northwest of the city.

Deam's untiring research resulted in the establishment of a state Forestry and Conservation Department. For years he was the State Forester and is one of the state's foremost authorities on matters of conservation. Deam was the author of the Tax Reduction Act, considered one of the best forestry laws ever written. At present he is writing "Flowers of Indiana," to follow his other three books dealing with trees, grass, and shrubs. All were published by the state. Deam is officially connected with the state as Research Forester.
