g distance without tiring. Tame swans do not fly far.

4. The bill of the swan is broad, and pointed like that of the goose,
but a little longer. Below the eyes, and at the base of the bill, a
narrow band of black extends across the front of the head.

5. The swans run in pairs. The mother swan lays from five to eight
eggs, and hatches them in six weeks. The young swans are called
cygnets. They are covered with down, and are able to walk and swim
when first out of the shell.

6. The father swan watches the nest, and helps take care of the young
ones. He will fly at anything that comes near, and he is able to
strike terrible blows with his wings. He can drive away any bird, even
the eagle.

7. Swans usually build nests of a few coarse sticks, and a lining of
grass or straw. They have a curious habit, however, of raising their
nests higher, and of raising the eggs at the same time.

8. At times they seem to know that some danger threatens them, and
then they turn their instinct for raising their nests to some purpose.
A person who observed all the facts tells this story:

9. For many years an old swan had built her nest on the border of a
park, by the river-side. From time to time she had raised her nest,
but never more than a few inches.

10. Once, when there had been no rain for a long time, and the river
was very low, she began to gather sticks and grasses to raise her
nest, and she would scarcely stop long enough to eat.

11. She seemed so anxious to get materials for nest-building that she
attracted the attention of the family living near by, and a load of
straw was carried to her. This she worked all into her nest, and never
stopped until the eggs had been raised two and a half feet.

12. In the night a heavy rain fell, the river flowed over its banks,
and the water came over the spot where the eggs had been; but it did
not quite come up to the top of the new nest, and so the swan saved
them.

LESSON XII.

_DOVES AND PIGEONS._

[Illustration: The Bath.]

1. Everybody likes the dove; it is such a pretty bird, and is always
so clean. It flies all about the yard, the garden, and the street.
Even the rudest boys do not often disturb it.

2. It is about the size of a half-grown chicken, and looks more like a
chicken than any of the other birds we have studied.

3. The doves about our houses are usually white, or a bluish gray.
They live in pairs, each pair having its own nest, or home; but wher
