FORESTRY PRACTICE.

| Pure and Mixed WOods-SOme Trees
| Demand Light-Others Bear Shade.
A forest may consist of single spe-
cies, when it is known as a pure wood.
| or of different species, when it is
known as a mixed wood. Pure woods
are seldom found. While they are
more easily managed than mixed
woods, the dangers are greater, and
the practice is seldom advisable How
| ever, mixed woods of few species are
generally more desirable than those of
many species.
When different species are grown to-
gether, the light conditions demanded
by each become of paramount impor-
| lance. Certain trees demand full ex-
posture to the sunlight and will not
grow in the shade of other trees. They
are known as light demanding trees al
together Generally trees with light
and scanty foliage belong to this class,
although there are some exceptions
The birches, pines, honey locust, black
locust, black cherry, ash and chestnut
belong here. Other species thrive in
partial shade and are known as shade
bearing trees. Among these are the
beech, maple, hemlock and oaks. If,
then, light demanding and shade bear
ing trees are planted together, care
must be taken that the former are more
rapid growers or else that they are Civ
en- sufficient start to enable them TO
keep in the lead.
Thinning becomes one of the most
important operations in forestry. Here,
again, the light conditions are all i'm
portant and must be studied carefully.
1t is well known that a tree which
grows in the open field becomes bread,
sturdy and vigorous, beautiful to look
upon, but useless to the lumberman.
In forest management just the reverse
of this type is demanded. The boles
must be tall and straight and taper as
little as possible. To secure this the
forest should be thinned but lightly in
it's earlier years until the trees have at
tanned their principal height. Thinning
may then be increased. and these tall,
slim boles will increase in size, making
the type of tree most desired. BY this
method the annual layers of growth

of timber better because the tree grows
less rapidly in it's earlier years than it
would do under normal conditions.
Nature must be made to do her own
pruning in forest management, and,
like all other primers, her work will be
more effective if done when the branch
es are small. When trees stand thick

killed out from want of light while yet
small; hence no large knots remain to
injure the quality of the timber.
Statistics taken from the Black forest
as to the number of trees per acre
growing In forests Of different ages
show the averages to be about as fol-
lows: At 20 years, 1000 trees per acre;
at 4G years. 1000; at 60 years, $50; at
80 years, $50; at 100 years, $50. The
number Of trees per acre win need to
vary with conditions Of soil, climate
and altitude, but these figures may give
a general idea of the great difference In
number between young forests and old
forests properly managed.
The Sugar Beet Boom In Michigan.
The beet sugar industry In Michigan
is making more rapid strides than in
any other section of the country. This
year over $1,000 acres of beets are 60
Ing into sugar. Next year the seventeen
factories will require 5000 acres each,
or total of $4,000 acres. This is rap
i'd development, but. when it is remem-
bered that 1t will take 100000 acres of
beets to supply enough sugar to furnish
Michigan alone it can be seen that the
industry is far from being overdone.
1t also indicates the possibilities of the
sugar beet culture in the United States.
