ARBORETUM ET FUUTICETUM BRITANNICUM. 



free soil, somewhat deep, and with a dry subsoil. All the varieties are pro- 

 pagated from im])orted seeds, which may be sown in the same aiitmim in which 

 they are received ; or, perhaps, kept in a rot heap for a year, as they lie two 

 winters and one sunnner in the ground before germinating. The plants grow 

 exceedingly slowly for 4 or 5 years, seldom attaining in that period a greater 

 height than from 1 ft. to 2 ft. When they are to be removed to any distance, 

 they are best kept in pots ; but, the roots being small and numerous, large 

 plants of P. Ccmbra transplant better (when they are not to be carried to too 

 great a distance) than most other species of Pinus,
