THE
Protection of Woodlands
Authorized translation from the German of
Kauschinger-Furst’s “Waldschutz.” By John Nisbet,
D’dic., of the Indian Forest Service, author of
“British Forest Trees, and their Sylvicultural Char-
acteristics and Treatment.”
1 VOL., 8vo, with colored plates, - $3.50
The various portions are dealt with tersely, and
from a thoroughly practical standpoint. Asthereis
no special work on Sylvicultural Entomology in
English, the chapter on noxious Forest Insects has
been somewhat amplified.
EpMUND B. SoutHwIckK, Ph.D., Entomologist of
the Parks of New York City, and Secretary of the
New York State Forestry Association, says:—
“To the forester, ‘The Protection of Woodlands’ is
invaluuble in that it cares for his possessions in hot and
cold, wet and dry conditions; protection against plants
and animals, forest offences and forest fires, and, what
is of great economic importance, protection against
forest sects. Over one-half of this valuable treatise is
devoted to insects alone, and no entomologist should be
without it. Theillustrations are exceedingly vainable,
and I cannot too highly recommenda it to allnatiuralists,
for the subjects have been handled in a masterly
manner.”

INTRODUCTION
HE following exercises have been arranged for use in connection
with Gray’s “How Plants Grow.” So far as 1s possible the lessons
are based upon careful study of specimens. Blank pages are
inserted for drawings and records of observations.
The work is designed for children twelve and thirteen years of age,
but it can easily be adapted to older pupils.
The first four lessons are spent in the study of typical forms of seeds
and seedlings. In Lesson III space is left for further work if desired.
If the lessons are begun in the spring, leaves and their modifications are
reached in May and form good subjects for summer work. Lesson XII
suggests several topics for reading and simple experiments.
In the autumn and winter months, material is easily obtained for the
study of buds and branches, flowers and fruits. Simple descriptions of
plants are begun with the early bulbous plants. Lesson XXV is intended
for a summary of terms made by the pupil, to which may be added any
technical terms needed for identification of our common flowers.
Newell’s “Botany Readers” furnish valuable supplementary reading
throughout the course. The “Outlines of Lessons in Botany,” by the
same author, are very helpful to the teacher,
In the arrangement of topics and choice of subject matter an earnest
attempt has been made to work out a practical course in Botany under
the ordinary limitations of science work in a city private school whose
sessions are held chiefly during the wiuter months.
Thanks are due to Miss Howell of Barnard College for her criticisms
and suggestions, and also to Mrs. Jane Newell Moore for the careful
directions for experimental work contained in her books.

TWENTY-FIVE FORMS FOR PLANT DESCRIPTION.
LESSON I.—Study of the Seed and Seedlings of the Squash.
Describe the shape, surface and color of the seed. Open a seed that has been
soaked in water over night and find the seed-coats. Separate the seed into halves
and sketch, showing the tiny connecting stem and the little leaf-bud. Compare
these parts with a squash seed which has just begun to grow and with another
which has been growing some time. What changes do you notice in the halves of
the seed? Mark these the seed-leaves or cotyledons. The little bud is called the
plumule and the connecting stem the caulicle. What happens to the cotyledons as
the plant goes on growing? Can you give a reason for this?

scar where the bean was attached to the pod. Open the seed which you have
soaked and sketch the little plant. How many seed-coats has the bean? Study
the plant in different stages of growth and make drawings, marking the cotyledons,
plumule and caulicle. What happens tu the cotyledons as the plant grows? How
do the leaves following the cotyledons differ from them and from one another in
form and arrangement on the stem?

Where is the albumen stored in the almond, walnut, flax, acorn, apple and castor-oil
bean? Make a list of the seeds we use for food and try to find out whether the
albumen is stored within or around the embryo. How does the arrangement of the
albumen influence the growth of the cotyledons?

form and arrangement of the scales. Are the scales alike in color and thickness ?
Can you explain any difference? What do you find within the scales? Examine
the largest buds for flower-clusters. Where are they placed? In how many ways
are the leaves and flower-clusters protected? How are the buds arranged on the
stem? Where were the terminal buds of last year? What scars did they leave?
How many inches has your branch grown this summer? Find the age of the whole
branch and of each twig. What scars were made by the leaves? Is there any
correspondence between the dots on the leaf-scars and the number of leaflets?
What causes this? What do the leaf-scars show about the leaf-arrangement ?
Look for the round, flower-cluster scar at the forking of two branches. Why did
blossoming affect the growth of the branch ?

LESSON XVIII.—The Structure of Stems.
Sketch a cross-section of a horse chestnut branch showing the pith, the sur-
rounding rings of wood, the sap-wood and the layers of bark. How do the rings
show the age of the branch? Examine a cross-section of a large branch and count
the rings. Are they of the same width in all parts? Can you account for any
difference? Why is the outer bark of an old tree full of ridges and cracks? Why
does the birch bark peel off? Name two plants of which we use the woody fibres
of the inner bark. How is cork obtained?
Sketch a cross-section of a cornstalk, marking the hard rind, the pith and the
bundles of woody fibres. How does the arrangement of the pith and wood differ

LESSON XXIV.—Inflorescence.
The simplest form of inflorescence, or manner of blossoming, is that in which
the flowers occur singly in the axils of the leaves or at the ends of the stem. These
are called solitary flowers.
If the blossoms are more numerous and are brought more closely together a
flower-cluster is formed. In this arrangement each flower grows from the axil of a
leaf, but the leaves are usually very small and inconspicuous. The leaves of a
flower-cluster are called Bracts. The stalk of the cluster is called the Pedunele,
and the stems of the individual flowers are Pedicels.
The most common forms of flower-clusters are the Raceme, the Spike, the Head,
the Umbel and the Corymb. The Raceme is a cluster with the flowers arranged
on the sides of the stem, as in the Lily-of-the-Valley. If the flowers grow on the
stem without pedicels the cluster is called a Spike, which we see in the Mullein.
The Head is a rounded flower-cluster with a very short body, as the Red Clover
and Dandelion. An Umbel is a flat-topped cluster in which all the pedicels start
from the same point, like the sticks of an umbrella. The Meadow-Parsnip and the
Carrot blossom in Umbels.
The Corymb is a flat-topped cluster which is like the Raceme with the lower,
pedicels lengthened so that all the flowers are brought on a level, as in the
Hawthorn. In what ways do flower-clusters assist cross-fertilization ?
