That portion of the P. & O. system which lies within the boundaries of the Buckeye State is known as the Ohio division, and the headquarters are at the little town of Wadsworth, which happens, by a fortunate chance of geographical position, to be almost exactly midway between the ends of the division. A hundred miles to the east is Parkersburg, where the road enters the State; a hundred miles to the southwest is Cincinnati, where it gathers itself for its flight across the prairies of Southern Indiana and Illinois; and it is from this central point that all trains are dispatched and all orders for the division issued. Here, also, are the great division shops, where a thousand men work night and day to repair the damage caused by ever-recurring accidents and to make good the constant deterioration of cars and engines through ordinary wear and tear. It is here that the pay-roll for the division is made out; hither all complaints and inquiries are sent; and here all reports of business are prepared. In a word, this is the brain. The miles and miles of track stretching east and west and south, branching here and there to tap some near-by territory, are merely so many tentacles, useful only for conveying food, in the shape of passengers and freight, to the great, insatiable maw. In fact, the system resembles nothing so much as a gigantic cuttle-fish. The resemblance is more than superficial, for, like the cuttle-fish, it possesses the faculty of "darting rapidly backward" when attacked, and is prone to eject great quantities of a "black, ink-like fluid,"--which is, indeed, ink itself--to confuse and baffle its pursuers. The headquarters offices are on the second floor of a dingy, rectangular building, the lower floor of which serves as the station for the town. It is surrounded by broad cement walks, always gritty and black with cinders, and the atmosphere about it reeks with the fumes of gas and sulphur from the constantly passing engines. The air is full of soot, which settles gently and continually upon the passers-by; and there is a never-ceasing din of engines "popping off," of whistles, bells, and the rumble and crash of cars as the fussy yard engines shunt them back and forth over the switches and kick them into this siding and that as the trains are made up. It is not a locality where any one, fond of quiet and cleanliness and pure air, would choose to linger, and yet, in all the town of Wadsworth, there is no busier place.
