free soil, somewhat deep, and with a dry subsoil. All the varieties are pro- 
pagated from imported seeds, which maybe sown in the same autumn in which 
they are received; or, perhaps, kept in a rot heap for a year, as they lie two 
winters and one summer 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 | 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. Cémbra transplant better (when they are not to be carried to too 
great a distance) than most other species of Pinus.
