In most pine-forests : New En^^land to Georgia. Tj . 

 May. V. V. The Yellow Pine is the most in use for 

 building of houses as well as shipping. Mr. Lainbert's 

 note oii this species says, " The height and size of 

 P. varudilis I have taken from Wangenheim, who 

 saw it growing in America, and see no reason for 

 doubting his auihorily."

On the edges of ponds and sv/amps : New Jersey to 

 Carolina. T^ . May. v. v. This and the preceding 

 species ripen their seeds only after the second year. 

 I strongly suspect them to be only varieties ; and if it 

 had not been introduced as a species by a very good 

 figure of Michaux's, I should have only given it as 

 such.
