(Denoted by capital letter.) 



State: Pennsylvania. County: Clearfield. Town: Dubois. 



Longitude : 78° 45'. Latitude: 41- 3'. Altitude: 1.200 to 1.500 feet. 



General configiu^ation: Plains hills plateau moiDitainoiis. 



General trend of valleys or hills : (Not noted.) 



Climatic features: (Meteorological tables furnished.) 



General forest conditions of the region: This forest area, in 1876, extended over 

 20,000 acres. The lumber operations carried on for twenty years by Mr. Du Bois 

 have left only from 1,500 to 2,000 acres of standing timber in a primeval condition. 



Three typical forms of forest conditions are suggested to the observer: 



(1) Hemlock and white-pine forest, with an admixture of mature hardwoods and 

 a number of young hardwoods and young hemlock, which form the undergrowth. 



(2) Hemlock mixed with white pine, with scattering hardwoods. The under- 

 growth, usually moderately dense, consists mainly of young hemlock with the ad- 

 mixture of young hardwoods. 



(3) Hardwoods intermixed with white pine and scattering hemlock. The under- 

 growth here consists mainly of young hardwoods. 



Among the bardwoods the oak, birch, and the maple form the staple of the hard- 

 wood forest, while the beech, the chestnut, the hickory, the cucumber, the ash. the 

 cherry, and the basswood are comparatively few in number. 



The region has a uniform soil and subsoil, as may be judged by the sample areas 

 NN 5. 6, and 7, and is well ])rovided with moistitre by the many streams crossinir it 

 all over in difi'erent directions.
