logs
and stones. Try to tame it by placing food where it can reach it and,
finally, try to have it feed from your hand.

Find out why there is no loose soil around the entrance to its burrow,
whether more families than one live in one burrow, whether the chipmunk
comes out during winter, or how early in the spring. Learn to
distinguish the sounds of the animal, as expressing alarm, surprise,
anger, playfulness.

_To the teacher._--Chipmunks carry grain, etc., in their cheeks.
Frequently these are so full that they must be emptied to permit them to
enter their burrows. It is not uncommon for several to spend the winter
in the same burrow, having a common storehouse connected by passages to
the main burrow. These little animals are easily tamed and soon learn to
take food from the hand. They are not hibernating animals, for they
store food for winter, and though they are not asleep all winter, yet
they rarely come out of their burrows while there is snow on the ground.

EASTERN SWALLOW-TAIL BUTTERFLY

No butterfly is more suitable for study by the Junior Forms than the
Eastern Swallow-tail. It is one of the most beautiful and attractive of
our butterflies and lays its eggs so accommodatingly on every carrot or
parsnip bed that it gives ample opportunity for observation.

If possible, have the pupils observe the insect in the act of placing
the eggs, one here and one there, on the under surface of the leaves of
the plants, noting the busy movements; discuss the advantage of
scattering the eggs, and also that of placing them on the under surface
of the leaves.

If the egg placing cannot be observed, there will be little difficulty
in finding the large yellow and green larva with a head shaped like
that of a miniature sea-horse. If the larva itself is not easily found,
the leaves stripped bare of green blade and the droppings on the ground
will reveal its presence.

Why was it difficult to see such a large, and now that it is seen,
conspicuous object? Lead the pupils to notice that the yellow and green
bands harmonize in colour with the green leaves and alternate streaks of
golden sunlight.

Does the larva feed by biting or by sucking? How many legs has the
larva? Cover the plant and larva with a paper bag, or inverted bottle,
or a lamp chimney with a gauze top until the larva is full grown; or
place the larva in a vivarium, feed it on carrot leaves, and observe its
growth.

When full grown, the larva builds for
