a useful tree for forming screens, and as a nurse for . more tender 

 trees. As a tree for planting in poor, dry soils and in exposed 

 situations it is equalled only by the Larch ; when planted as a screen 

 for shelter it is best mixed with the common Spruce and the hardier, 

 rapid-growing deciduous trees. Its rate of growth in the climate of 

 London, according to London, is from 20 to 25 feet in ten years, 

 and from 40 to 50 feet in twenty years.

 twelve fifteen involucral bracts, the anthers with an orbicular connective. 

 Cones usually in pairs or clusters of three, ovoid cylindric, 3 5 inches

Pinus Tceda is one of the most widely distributed of the Pines 

 inhabiting the Atlantic States of North America. It spreads from 

 Delaware southwards to Florida and through the Gulf States to 

 Texas. Except in the northern portion of its range where it prefers 

 the low lands adjacent to the Atlantic coast, it takes the place 

 of the southern Pitch Pine, P, palustris, inland spreading westwards 

 through South Carolina and Georgia to the Mississippi river. 

 West of the great river, the area covered by it is less extensive, 

 but in western Louisiana and eastern Texas it forms considerable 

 forests, and in Arkansas and the Indian territory it is the most 

 important timber tree of the country.
