54 ECONO^[IC BOTANY OF ALABAMA 



4. Common, especially on the tops of ridges, where they are not too 

 rocky. 



5. \'ery common on dry red hills, but a good deal of it is second 

 growth. In Tallapoosa County it seems to be the prevailing pine. 



6A. Common in dry woods; some of it second growth. 

 6B. On hills, but not in the sandiest soils. 

 6C. Same as 6A. 



7. On patches of red loam overlying the Selma chalk, and in old 

 fields. 



8. Frequent on dry uplands, especially in old fields. 



9. Abundant throughout, and cut by all the sawmills. 

 lOE. Common on uplands. 



low, 11. Dry ridges, often very slender. 



12, 13. Rather rare, in richer soils. Extends south to near Hurricane, 

 Baldwin County. 



Pinus glabra, Walt. Spruce pine. 



(Map 8, Figs. 10, 11) 



A handsome tree, remarkable for the smooth bark on those 

 parts of the trunk that are less than 8 or 10 inches in diameter, 

 the soft wood, unarmed cones, and bluish gray foliage. (In all 

 these respects it resembles the northern white pine, but it is not 

 very closely related to that.) It ocasionally attains a diameter of 

 42 inches and a height of 80 feet, but on the average it is probably 

 no larger than the preceding species. Its leaves and cones are 

 about the same length as those of P. cchinata. It blooms usually 

 in March. 



The wood is the softest and lightest of all the Alabama pines, 

 with the possible exception of P. clausa (which is rare in this 

 state). It answers very well for crates and interior finish, and 

 where there is enough of it it is used to some extent for fences, 

 weatherboards, etc., but it is not very durable. It would doubtless 

 make a good ornamental tree, on account of its handsome appear- 

 ance and its preference for richer soils than most other pines.

This species grows mostly in hammocks, ravines, and bottom 

 lands, where fire is rare, and it seldom if ever makes pure stands, 

 as most other conifers do, but is mixed with magnolia, beech.
