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 our food and clothing, do not grow of themselves.

The ground must be plowed, the seeds planted and taken care of while growing.  So, outside the city, you may see a great many people at work raising grain, vegetables, and other plants.  This occupation we call agriculture or farming; the people we call farmers.

Animals, as well as plants, furnish much of our food.  All meat comes from animals.  We get milk from cows.  From milk we make butter and cheese.
