Texas, it extends to the valley of the Colorado. 
The loblolly pine is perhaps the most aggressive of all the 
pines of our area. It is known in many localities as ‘‘old-field 
pine,’’ because of its ability to take possession of, and reforest 
old fields where corn and tobacco once grew. It will in all

in the manufacture of doors and different kinds of finish.

The trees of our area are too small to be of much use for 
timber. The chief product of value is the nut, which is of 
some commercial importance.
