BIRDS OF OHIO 



BY J. M. WHEATON, M.D. 



The State of Ohio re situated between 38° 25' and 42° north latitude 

 and 80° 30' and 84° 5' west longitude from Greenwich, or 3° 30' and 

 7° 50' west from Washington. It is thus the most southern of the 

 northern tier of States, its northern border corresponding in latitude 

 with the southern border of Michigan and New York. Its extreme 

 length is, from east to west, about 220 miles; its greatest width from 

 north to south about 210 miles. Its area is approximately 40,000 square 

 miles. About two-thirds of the State is under cultivation, and of the 

 remaining third nineteentwentieths is woodland. Before cultivation a 

 few small prairies in the western and central portions of the State inter- 

 rupted the general woodland. 



Two-thirds of the State may be considered as forming a part of the 

 great Mississippi Valley, while about the northern third is in the basin 

 of the great lakes. The water-shed which divides the streams flowing 

 into Lake Erie from those tributary to the Ohio, traverses the State 

 from near the north-ea&t corner in a south-westerly direction as a low 

 ridge, the greatest elevation of which is nowhere more' than 1,400 feet 

 above the sea. This water-shed is lower in Ohio than in Pennsylvania 

 and New York. 



The variation.s in the general surface of the State are not great. The 

 elevation of L ike Erie is 565J feet, and that of Cincinnati, the lowest 

 point, 429 feet above tide .water,, or 135 feet below ,the Lake. 



The section of the State lying between the water-shed and the Lake 

 is generally level, presenting a gradual slope to the north. The central
