GENERAL DESCRIPTION OF STATION. 

 [Denoted by capital letter.] 



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



Longitude: 78 45 . Latitude: 41 3'. Altitude: 1,200 to 1,500 feet. 



General conliguration : Plains hills plateau mountainous. 



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



Climatic features: (Meteorological tables furnished.) 



General forest conditions of the region : This region in 1876 extended over 20,000 acres. The lumber operation 

 carried on for twenty years by Mr. Du Hois left for the present only from 1,500 to 2,000 acres standing timber iu 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 hard- 

 woods and young Hemlock, which form the undergrowth. 



(2) Hemlock mixed with White Pine, -with scattering hardwoods ; the undergrowth usually moderately dense, 

 consists mainly of young Hemlock -with the admixture of young hardwoods. 



(3) Hard-woods intermixed with White Pine and scattering Hemlock. The undergrowth here consists mainiy 

 of young hardwoods. 



Among the hardwoods, the Oak, Birch, and Maple form the staple of the hardwood forest, while the Beech, 

 Chestnut, Hickory, Cucumber, Ash, Cherry, and Basswood are comparatively few in number. The region has a 

 uniform soil and subsoil as it may be judged by the sample areas NN. 5, 6, and 7, and is well provided with moisture 

 by th(j many streams crossing it all over in different directions.
