vegetative growth. It has been found by Roberts" that the fruit-
ing habit of cherry trees is directly related to the amount of
annual growth made the previous season. If the annual growth
is short, that is,.under 6 inches, the lateral buds will be mostly
blossom buds, and a lateral fruiting system results since there are
few leaf buds to make spurs. On the other hand, if the annual
growth is long, that is, over 12-14 inches, the lateral buds will be
mostly leaf buds with a consequent spur fruiting system. The
variety modifies the above figures slightly, since the Montmorency
is found to have more leaf buds per given length of growth than
the Early Richmond variety. The season, age of tree and part
of tree are also considered as factors affecting the ratio between
length of growth and blossom bud formation.
The spur fruiting system is recommended by Roberts as the
better fruiting system, because of the greater hardiness of spur
buds, and the possibility of production for more than one season
on the same spur.
European and American plums produce blossom buds laterally
on one-year wood, and on spurs borne on two-year wood. The
lateral blossom buds occur either singly with a leaf bud or in a
group with one leaf bud between two or more blossom buds.
The spur blossom buds are formed laterally along a short spur.
The spur has no true terminal bud, but sometimes the "end bud"
of the spur continues in vegetative growth. If no vegetative
growth is made the spur dies after fruiting and becomes a short
stiff spine.
Japanese varieties of plums produce blossom buds largely as
lateral buds.

I have no idea of discussing this question entirely as related to
the technique of marketing methods. The past reports of the
Society show able discussion of many of the factors of handling
