Plains consisting of dry sand, and sea coasts, in North America, are abundantly stocked with 

 this species of Pine ""as the soil is too meagre to afford much nourishment, the trees growing in it (as 

 we are informed by Wangenhcim) remain low, full of branches, and attain but moderate strength. 

 Their wood is of short duration, being apt to become worm-eaten, and rotten. If they grow, however, 

 in moist and low places, they rise to a considerable height and strength, and occasionally afford timber 

 for ship building. The hark is greyish, rough, and cracked on old trees ; the leaves generally mcasrire 

 from five to six inches in length, but often more. They are pointed, flat on the upper surface, 

 furrowed on the under, pliable, and of a light green colour; there are always three m one sheath. 



This Is certainly a very distinct species from P.rigida (as Miller has made it), d.ffcrmg essen- 

 tially in the loose texture of its cones, their slight attachment to the branches, the mcurvature of 

 the spines of the scales, and the length of the sheaths or Fagin. of the leaves, which are longer 

 than in P. rigida. The cones of the latter are of a much harder texture, and will remain on the
