from other species. Some lumberiuen have ouly two 

 names for Southern pines : "heart pine" for longleaf, and 

 •'sap pine" for the others. These terms expres.s pretty 

 clearly the chief difference which lumbermen recognize in 

 tne Southern pines. Of course there are other differences, 

 some of which do not appeal so directly to the eye. Long- 

 leaf' pine is harder than the others, and stiffer, stronger, 

 and heavier than most. It is of slower growth and the 

 annual rings are narrower. The wood is generally but 

 not always of darker color than that of the other i)ines 

 associated with it. The longleaf pine occurs in the north- 

 ern two-thirds of Florida. Its reproduction is not gen- 

 erally vigorous, but in some sections many young trees 

 are taking possession of vacant places. As a whole, it is 

 doubtful if young growth can to any appreciable extent 

 make good the loss through sawmill operations, and the 

 result seems inevitable that longleaf pine supplies will 

 decline in the State, as in other . regions, until scarcity 

 results. The habit of frequently burning forest lands 

 perhaps works more harm to longleaf pine than to any 

 other tree, by killing the young growth. 



Cubcm Pine. — Next after longleaf, this species shows 

 longest use in the State. The same diiHculties as in the 

 case of longleaf pine are met in separating it from asso- 

 ciated pines. One is often mistaken for another. The 

 Cuban pine is known under several names. It grows in 

 nearly all regions of Florida where any pine grows. It 

 has thick sapwood and is resinous; the rings of annual 

 growth are wide; the wood is stiff and strong. As the 

 southern part of the State is approached, the Cuban pine 

 becomes smaller. A good many stands exist in which 

 the mature trees are too small to attract sawmills. It 

 responds to good soil, and patches of merchantable tim- 

 ber may be found, surrounded by scrub growth. 



Lollolly Pine. — This valuable timber tree belongs in 

 northern Florida, extending south to about the center of 

 the State. In quantity of timber manufactured in Flor-
