I^lY specimens were procured from the Royal Gardens at Kew. P. alba has its name from its bark 



being whiter than that of other species. It is found in America from the forty-third degree of north 



latitude northward, but farther southward it disappears, requiring a very cold chmate. In Canada, 



Nova Scotia, and the northern parts of New England, it grows in perfection, as Wangenheim n.forms 



us and covers the tops of mountains too bleak and of too bad a soil ^orF. Strobus. The growth o 



P alia is nearly equal to that of P. Mies. It flourishes on poor and rocky land, and also on gravel 



whe d ; a d :2ed with clay, and a little good mould. A soil apparently but just suffie.ent to 



Lid th;oots enables it to groJ. The flo^^ers appear towards the end of May. The cones npen at 



r eld of October. These are from two inches and a half to three mches nr length, a^.d almost one
