r the amount of depredation of which she may be guilty.

COMPARISON OF THE HORSE AND COW

Assign problems for the pupils to solve by observations made upon the
animals in the field or farmyard.

1. What features of build give to the horse greater speed than the cow?

2. Compare the movements of the heads of the horse and cow while
cropping grass. Account for the difference.

3. How has nature fitted the cow and the horse respectively, for
defence?

4. Which end of the body does the horse raise first when it is getting
up? Which end of its body does the cow raise first? Account for the
difference.

_To the teacher._--The horse is the swifter and more graceful runner
because the body is less bulky and the legs are longer and straighter.
In cropping grass the cow pushes its nose forward and breaks the grass
off, a process which is made necessary because the cow has no upper
front teeth. The strong, sharp horns, short, powerful neck, and heavy
shoulders are an efficient equipment for the cow's method of defence,
while the long, strong legs and powerful hindquarters of the horse
enable it to deal terrific blows with its hard hoofs. The horse rises
upon its forelegs before raising the rear of its body, while the cow
raises its hindquarters first.

THE SQUIRREL

FIELD EXERCISES

~Problems~:

Is it true that squirrels have little roads along the ground?

Does the squirrel come down a tree head foremost, or tail foremost?

Are a squirrel's feet close together or wide apart when it is climbing?

How many kinds of feeling can a squirrel express by its voice?

How does a squirrel open a nut?

Examine a squirrel's tracks in the snow; which foot-prints are in front?

Try to gain the confidence of a squirrel by never chasing it and by
placing some favourite food for it.

CLASS-ROOM LESSON

A tame squirrel is very desirable for concrete study.

Describe the shape, size, and colour.

Find out how the legs and feet are fitted for climbing and leaping.

Compare the length of the tail with that of the body. Of what use is the
tail in cold weather? Of what use is the tail in leaping?

Examine the teeth and find out how they are fitted for opening nuts;
gnawing wood.

_To the teacher._--The legs of the squirrel are short so that it can
press its body close to the tree when climbing. The claws are strong and
sharp and the hindquarters are very strong, and are, in consequence,
well fitted for leaping. The tail
