know, begins or is renewed In

from the agency Of seeds, comes about
in various ways-by tubers, bulbs, by
underground roots and stems. In the
tree the renewal results, first, from the
unfolding OF buds formed in the axis
Of last years leaves and all ready by
expansion to furnish the foliage and
twigs OF the season, and, second, from

chapter. The buds contain at base and

These carry forward the growth Of the

from buds. All development upward
takes origin in buds. In this respect,
however, the development OF a bud on
