The influence of the rivers, especially the Mississippi and the "Wabash, 

 in extending forests, is plainly marked. From the mouth of the Ohio 

 to the fortieth parallel are eleven counties, Alexander, Union, Jackson, 

 Kandolph, Monroe, Saint Clair, Madison, Jersey, Calhoun, Pike, and 

 Adams, and they average 37.3 per cent.; northward, on the Missis- 

 sippi, Hancock, Henderson, Mercer, Rock Island, Whitesides, Carroll, 

 and Jo Daviess, averaging 14.8 per cent. The tract between the 

 Saint Louis and Alton Ilailroad and the Illinois Eiver, in the prairie 

 belt, comprising Jersey, Greene, Scott, Morgan, Cass, Mason, Menard, 

 Tazewell, Woodford, Logan, Marshall, Putnam, Grundy, Sangamon, 

 fourteen counties, averages IG per cent. ; and the counties between 

 that road and the Chicago branch of the Central, comprising Madison, 

 Bond, Macoupin, Fayette, Effingham, Shelby, Montgomery,"Christian, 

 Kankakee, McLean, De Witt, Macon, Moultrie, Piatt, Ford, Will, and 

 Livingston, comprising seventeen counties, average 13 per cent. 



In some of the older States the proportion of woodland is quite as 

 variable as in Illinois. Pennsylvania has an average percentage of 31.9, 

 but Montgomery County has only 7.8, while Cameron has 8"8.3. The 

 mountain counties have high percentages. On the Delaware, Wayne 

 in the northeast has 50.9, and Pike, 7G. The northern tier has more than 

 an average proportion of wood, especially McKean and Warren, which 

 have respectively Gl and GO.l per cent. The counties bordering on Ohio 

 fall below an average. In the agricultural portion of EasternPennsyl- 

 vania the axe has left only a minimum of wood, Cumberland having only 

 11.7 ; Lancaster, 12.1 ; Chester, 14 ; Berks, 15 ; Delaware, near Phila- 

 delphia, has but 10; Montgomery, 7,8 ; and Bucks, 10,9. The accom- 

 panying outline map, with plain figures of percentage on each county, 

 will sliov,' the progress of destruction of forests in this State :
