The Ohio which forms the entire s.e. and a. boundary of the state, descends from an eleva tion of a little less than 1000 ft. where it leaves Pennsylvania and strikes the e. line of Ohio, and falls 600 ft. iu the 436 m. of its course around the state to the Indiana line. The drainage divide of the state is about one-third of the distance from the n. to the a., so that about one-third of the state clrains into the lake and two-thirds into the Ohio river. The summit level or dividing ridge runs from Trumbull co. in the n.e. to Mercer and Darke counties in the's.w., with an average altitude of less than 600 ft. above the lake. The state has, therefore, a general plane of 'descent from the n.e. to s.w. • he except don being the n.w. counties which rise on a gentle plane of ascent w. from the lake, into which they drain, through the Maumee river. The state has no moun tains. Its greatest local elevation is in Logan co. near the middle of the western half of the state, 1540 ft. above the sea. The.hilly or rolling surface of a large part of the Ohio river water-shed and the rounded bluffs that margin the large rivers are the remains of the great erosions by water of the original geologic plateaus. The Ohio river has worn its bed in many
parts from 500 to 600 ft. below the hilly summits along its valley, and its tributaries have worn similar though less deep valleys. The main streams flowing into lake Erie, beginning at the e., are: the Cuyahoga river, emptying at Cleveland and forming its harbor; the Black river. 30 m. w.; the Vermillion, 12 rn. farther; the Huron, 12 in. from it; the Sandusky, emptying into Sandusky bay; the Ottawa, emptying at Port Clinton; and the Maumee into Maumee. bay. All of them have harbors at their mouths. Of these lake streams the Maumee drains much the largest country. The rivers flowing into the Ohio are the Muskingum, emptying at Marietta; the Hocking; the Sciota, having Portsmouth at its mouth; the Little Miami, emptying 6 m. above Cincinnati; and the Miami proper, or Big Miami, joining the Ohio about 20 in. below Cincinnati. All these river valleys are beautiful and fertile throughout; but growing richer in soil rela tively from the e. westwardly; the two Mantis being the richest valleys on the Ohio slope; and the Maumee, the Portage, and the Sandusky, the streams flowing through the richest soils to the lake. Toledo, Sandusky, and Cleveland are the main lake ports. The low divide between the Cuyahoga and the Muskingum rivers emly suggested the Ohio canal from Cleveland to Marietta. The still lower divide between the estuary of the Maumee and the Miami river led to the construction of the Miami and Erie canal, 247 m. long, from Toledo to Cincinnati, finished in 1839. The Ohie river, notwithstand ing•an average descent ft. to the m., is navigable its entire distance along the state for steamers of considerable size at high stages of the water, and for barges at all stages. See OHIO RITE% The lake shores indicate either a subsidence of the waters or a lifting of the land, as there are several old beaches or ridges that mark old water lines of the lake, now respectively from 100 to 250 ft. above its present level.
