n the earth, as the metals and stone are
found; but it is made of clay, which is itself a part of the ground.

Have you ever seen a brick-yard? What are some of the uses of bricks?
What is the man called who builds houses of bricks?

Is glass taken out of a mine or quarry? No; but glass is made from sand;
which is also a part of the ground.

In laying brick or stone, the mason uses _mortar_. Mortar is made
chiefly of lime. Lime is made of stone which comes out of the ground.

If possible, visit mines and quarries. Take careful notice of all you
see, and on your return to school tell what you have learned.

LESSON XLIII.

HOW PEOPLE LIVE AND WHAT THEY ARE DOING

[Illustration: "DID YOU EVER HEAR OF PEOPLE WHO LIVE IN SNOW HOUSES?"]

Can you think of anything used in building houses that does not come
from the earth?

Do all people have large, fine houses of brick or stone to live in? What
is a tent?

[Illustration: WIGWAMS.]

A wigwam? Who live in huts? Did you ever hear of people who live in snow
houses?

[Illustration: HOUSES BUILT OF BAMBOO.]

In some places houses are built of bamboo. Bamboo is a kind of cane that
grows in warm countries.

What building is now going up in this place? Tell the use of stone,
brick, mortar, iron, tin, lead, and glass in building the house. Where
and how are they obtained?

[Illustration: "WHO LIVE IN HUTS?"]

We could not live without food. We must also have clothes to wear and
houses to live in. Besides these, we need schools, books, and churches,
which make us wiser and better. Now, if you think a little, you can name
many other things which we need to make our homes beautiful. To supply
us with all of these things, men must do many different kinds of work.

Where does the food we eat come from?

We get most of it from plants. Wheat, corn, peas, and beans are seeds of
plants. Almost all our bread is made from wheat. Beets, turnips, and
radishes are roots of plants. Lettuce and cabbage are the leaves of
plants.

[Illustration: "OUR BREAD IS MADE FROM WHEAT."]

Apples, peaches, pears, and other fruits grow on plants. All these we
use for food.

Plants also supply us with material for clothing. Some clothes are made
from cotton; cotton grows in the pod of a plant. Some clothes are made
from linen; linen comes from flax, which is a plant. Hats are made from
straw; straw is the stem or stalk of plants.

Now, these plants, which supply us with so much of o
