range, being found rather sparsely in Southern Pennsylvania, 

 North Carolina and Georgia. 



P. Tcsinosa, Alton. — Red Pine, Norway Pine. — Leaves in twoa, 

 five to six inches long, nearly cylindrical from long sheaths, 

 rigid and straight, dark green. Cones two inches long,- conical, 

 usually in clusters, scales without points. Branchlets with red- 

 dish smooth bark. Wood hard and compact, light-colored and 

 quite durable. A rather large tree, sixty to eighty feet high in 

 the Eastern States, but specimens have been found in Michigan 

 measuring a hundred and fifty feet. No large forests of this 

 species are known, but it is found in Pennsylvania, northward 

 to the Canadas, and west to Minnesota. 



P. rigida, Miller. — Pitch Pine. — heaves in threes, and froni 

 three to five inches long, from very short sheaths, rigid and 

 flattened, or slightly angled on 

 one side, of a bright, but not 

 very dark-green color. Cones 

 ovoid-conical, and of the size 

 and form shown in figure 57, 

 mostly solitary, but occasional- 

 ly clustered, three or four to- 

 gether ; the scales terminated 

 with a small, stout prickle. 

 Seed small, winged. A medium 

 sized tree, forty to seventy feet 

 high, with stem two to three 

 feet in diameter. Wood hard, 

 coarse-grained, full of resin, 

 and generally so well studded 

 with knots as to be of httle 

 value except for fuel. A rather 

 handsome tree when found 

 in good soil and with room 

 enough to grow without being 

 crowded. More abundant in 

 swamps and low grounds than 

 elsewhere, but often found of 

 large size on high, sandy land, slate and sandstone ridges. 

 Prom Maine to Georgia, east of the Alleghanies. 



Var. Serotina, Michx. (Pond Pine), has a little larger leaves 

 and more ovate cones, otherwise the same as the species. Dr.
