“ The river valleys of the Wabash and Whitewater are particularly fertile. The climate is changeable and marked by extremes. Nearly one-eighth of the area is open prairie, and well adapted to agriculture. The trees include the white, red, black, and blue oak, ash, beech, hickory, sycamore, elm, tulip, black walnut, red and sugar maple, tamarack, sumach, dogwood, and wild plum. ”

“ The rivers are mostly affluents of the Ohio and include the Indian Kentucky, Silver, Indian Blue, Big Pigeon, Little Pigeon, and Laughery. The Wabash, rising in Ohio, flows 500 mils through the State, and is navigable for 300 miles. ”

“ Block coal, used in pig iron smelting, is mined in blocks weighing upward of a ton each, and cannel coal and peat are found in abundance. Quarries of building stones cover an area of 200 square miles, adjoining the coal measures. The coal production of the State in 1918 was 27,325,000 tons, a gain of 785,000 tons over the production of 1917. ”
