free soil, somewhat deep, and with a dry subsoil. All the varieties are propagated
from imported seeds, which may be sown in the same autumn in which
tliey are received; or, perhaps, kept in a rot heaj) for a year, as they lie two
winters and one summer in the ground before genuinating. The plants grow
exceedingly slowly for 4 or 5 years, seldom attaining in that jieriod a greater
iieiglit than from 1 ft. to 2 ft. Wlmn they are to he removed to any distance,
(hey are best kept in pots ; hut, the roots being small and nunuii’ous, large
plants of P. Canòra transplant hotter (when they are not to he carried to too
great a distance) than most oilier species of Pimis.

The wood of tliis tree
is remarkably white when
newly sawn into planks ;
wiience the common Ame-
I'lor. p. suùbuB. rican name for it of white
pine. The rate of growtii iu Britain is, except in very favourable situations,
slower than that of most European [lines. Nevertheless, in the climate of
London, it will attain the height of 12 or 13 feet in 10 years from the seed
When planted singly, like most other pines, it forms a branchy head; but,
when drawn up among other trees of the same species, it has as clear a
trunk in Britain as in America. The wood is mpre employed in America
than that of any other pme, serving exclusively for the masts ofthe numerous
vessels constructed in the northern and middle states. 'Fhe soil and situation
oiiglit to be favourable, otherv\ise the tree will not thrive. Seeds are [irocured
ill abundance; and the plants, when sown in spring, come up the first year,
and may be treated in the nursery like tliose of the Scotch pine.
