 botanic names are given only for reference. 



14. The weights are from several sources. They are 

 given for dry wood. Air-seasoned wood is about 15 per cent 

 heavier than dry wood; and green wood is often twice as 

 heavy. 



15. The following notes should be used in connection 

 with a study in the woods of bark, leaf, branching, bud, 

 flower, fruit, and seed. It was thought best not to give full 

 descriptions, the aim being to stress the things that are most 

 striking to the observer, and therefore of most use in identi- 

 fication. 



16. The local uses of the different kinds of wood should 

 also be studied. 



(a) The Conifers 



17. Longleaf pine, PINUS PALUSTRIS. The needles are 

 from 8 to 18 inches long, 3 in a cluster, in dense tufts at the 

 ends of the branches. The cones are from 6 to 10 inches 

 long and slightly curved. The seeds are about half an inch 

 long; they are provided with papery wings which help scat- 

 ter them away from the trees that bear them. 



18. The wood weighs about 39 pounds to the cubic foot. 

 It is hard, tough, and durable in contact with the soil. It is 

 used for many purposes, from pig-pens to interior finish. 

 This and the Cuban pine are the chief sources of naval 

 stores. 



19. It occurs in the Coastal Plain, in some places ex- 

 tending scatteringly into the Piedmont Plateau. In the 

 western part of the State it extends even into the Mountains. 



20. Cuban pine, PINUS HETEROPHYLLA. This is some- 

 times called slash pine. The needles are from 8 to 12 inches
