PROPAGATION OF TREES. 211 
another variety, either for ornament or other purpose, 
demand distinct treatment. Variations from original 
species are also sometimes produced by the transfer of a 
plant from its primitive soil and climate to one of great- 
er or less richness and intensity ; and when this change 
is so effective as to produce its natural dissolution, it 
then becomes necessary to convey the reconstructive 
members in part from a tree of the same variety, and by 
gradual insertion or inoculation of them produce or re- 
construct it to its natural perfection. Variations of spe- 
cies produced by such transfers are sometimes an im- 
provement upon the original, producing, as they often 
do, pleasing variety of color and form of foliage which 
contribute largely to the genera of reserved growths. 
‘Whenever these varied species present quality and merit 
to warrant their reservation either for exceptional orna- 
ment or productiveness, they should be closely attended 
to; and, when being removed from the seed-bed, ought 
to be so planted as to be conveniently superintended,when 
every characteristic of their growth and appearance 
should be noted so as to supply detail of their merit and 
worthiness. From such varieties, or “sports,” our many 
cultivated fruit-trees and flowering-shrubs have been ob- 
tained; produced as they have been by the breaking-up 
of the natural habit of the original wild genera, they 
afford variety of color and foliage highly pleasing and 
ornamental. These valuable additions should on no ac- 
count be lost sight of, but increased, as there is a likeli- 
hood of the original tree or shrub being lost by the 
course of nature or by accident ; and for this purpose 
propagating by layering, budding, and grafting is most 
usually resorted to. 
SEEDING. 
Raising trees from seed requires more care and atten- 
tion than persons unacquainted with their growth are 
inclined to consider. The leading thought of inexperi- 
ence is that nature supplies every want for the nourish-
