In the early days most of the cut-over land was cleared. This was particularly true prior to 1860. Most of the large lumbering operations between 1860 and 1900 were conducted in the mountainous parts of the State, and during this period only a small percentage of the lumbered areas was cleared for agricultural purposes; and of the land that was cleared a large percentage has since^been abandoned and is slowly being restocked naturally with a growth of forest trec^s. , , ., . v i. lOAft The forest area of Pennsylvania reached its minimum about 190U when there were approximately 12,000,000 acres of forest land in the State From 1900 to 1922 a large acreage of farmland was abandoned, for it wa^ found that most of the cleared mountain land was not suit- able for agricultural purposes. This abandoned farmland ^\^^^Srt- stocked naturally with trees and the total forest area of the Stat«. is now (1922) 13,024,399 acres. ^ On the basis of present indicating factors it seems conservative to estimate that there will he approximately IWOOO acres of forest land in Pennsylvania 50 years from now (197J).
