amount and three to five acres is better.
To those of US who are accustomed to
school yards 4 rods by s rods this may
seem like an awful waste of land. but
really the small school yard contains
the wasted land while the large one can
be put to good use. After the choice
Of the location, or with school grounds
already located, the ground should be
broken deeply, except that portion re-
served for b playground. Before plow-
ing, the ground should be we'll manured.
In regard to the playground area it may
be advisable to break this and reseed
to some of vi hardy tame grasses.
Many different kinds of arrangements
and paintings could be suggested but in
order to make this paper short we will
confine ourselves to a study of one
which has been suggested by Prof. C.
B. Waldron as being particularly appli-
cable to this state. With the school
house facing south upon the north and
west sides of the school grounds. which
we may say measures 20 rods wide end
"a rods deep, thus covering about three
acres, should be planted to a shelter
belt deep enough to afford protection
from the wind and to prevent the snow
from drifting much around the buildings
or onto the play ground. This shelter
belt should measure at least E rods in
width or SO feet. This will allow IL
rows Of trees 8 feet apart. While a
wider shelter belt might be preferred
this will do. The rows OF such a shell
ter belt would have a total length of
ATS rods in round numbers.
Let US plant the nine of the rows of
this shelter belt to deciduous trees. We
will put in Seeding trees, preferably
green ash and Norway poplar. The
number of green ash and poplar required
will be about $50 each. We want to
secure trees having a height of "a to
80 inches. The Green ash and the pop
lar are to be alternated in the rows.
thus each row will be composed of
equal numbers of both kinds. They
may be planted at q distance, say of
3 feet apart Some of these may per-
haps fail to grow. The poplars will
want to be removed in the course of
time and if the ash trees are too thick
they always are valuable for transplant
ing.
The two outside rows and one inside
may be planted to western bull pine,
Pinus ponderosa, which is native 10 the
southwestern portion of the state. Out
side Of the lows of pines it may be ad-
visible on the west side, if the school
house fronts south, to plant q hedge
snow break. This may be of white
willow. but probably the Siberian sand
thorn or sallow thorn is to be preferred.
The bull pines may be planted S feet
apart. At this rate it will require about
400 pine rees. Transplanted pine trees
Of 8 to IL inches in height should be
secured from a good nursery, shipped
by express and carefully planted. par
ticular cart being taken that the roots
are not allowed to to be exposed to the
air.
DIRECTIONS FOR PLANTING
The trees may be planted according
to the following directions: In plant
ing the trees we take ground at least
two years old. Deep burrows are plowed
every 8 feet. A pail Of very thin mud
is prepared and q bunch of each kind of
trees kept in it. Trees are planted by
one man, using q spade. The spade is
inserted at the bottom of the furrow and
worked back and forth to form a WEDGE
shaped opening. The root Of the tree
Is inserted as the spade is Withdrawn.
After the removal of the spade dirt is
pressed firmly around the roots of the
tree. The furrow il partly filled In by
q corn cultivator, %straddline each row
Of trees. It Is better to leave the furrow
only partly filled in, for by doing 90
water from the rains will RON into the
fu1row, keeping the ground moist. The
