The vitamins are named by letters of the alphabet.

Vitamin A is needed by the eyes.

There is Vitamin A in milk and green vegetables.

It can be stored by the body.

Vitamin B cannot be stored.

It must be supplied all the time by some of the food we eat.

The skins of grain of all sorts have Vitamin B in them.

Page:32

Vitamin C is very important to the body.

Without it our teeth become loose and our arms and legs weak.

Lemons, oranges and tomatoes have Vitamin C in them.

Vitamin D is the sun vitamin.

We get it in milk and eggs and from sunlight on our skin.

There are other vitamins,but these A,B,C and D,

are the most important.

Page:33

Every person must have air and water and food to keep alive and must have these vitamins to keep well.

How do we know this?

How do we know what food keeps us well and healthy?

We know from the effects on us and on animals of going without one sort of food or another.

That is how we see which foods give us energy,

which make us fat and which make us able to keep healthy.

Scientists are putting together more and more knowledge about the sorts and amounts of food that our bodies need.

Too little food or too much of the wrong food is bad for a person.

The right amount of the food will keep a person feeling well and strong.

Some people need a little more or a little less of one or another sort food than others.

Page:34

Where do we get our food?

We get much of it from the earth.

We use some sorts of animals and birds to give us food.

Great parts of the earth are covered with grass,a plant which grows with narrow green leaves and puts down roots quickly.

There are more than three thousand different sorts of grasses growing.

Grass has very small seeds which are used as food by birds and small animals.

We have discovered how to grow grasses with larger seeds.

Wheat,rice,corn,and other grain come from grass.

The grain lands of the world have been planted by people.

From grain we get an important part of the food that gives us energy.

Page:35

The grasslands of the earth supply food to many different animals.

From some of them we get meat and milk.

From milk we make butter and cheese and other foods.

From birds living on grain we get eggs and meat.

Seeds planted in good earth supply grains and fruits and vegetables of many sorts.

The seas and rivers supply fish and some sea plants for food.

Page:36

People had to go from place to place for food until they discovered how to grow grain.

Uncooked meat and parts of plants were all they have to eat until they made use of fire.

And they had to get new supplies of food every day.

They hadn't any way of keeping it good

How could a family get enough good food for itself without having to go looking for it every day?

When a family started growing grain,

it had time to do other things than get food day by day.

It could keep a supply of grain on hand through the winter until the next spring .

It could make a home itself and keep animals for its use.

Page:37

Bread ,which is made from flour ,supplies us with energy and is the chief food of many people .

A small amount of seed planted in the earth can grow great amounts of good grain.

A good farmer in a good wheat-growing part of Canada,for example ,

will get as much as thirty or forty pounds(lbs.) of grain for every pound of seed he puts into the earth.

Farmers grow grain for public use.

They get money for it.

In eastern countries more rice is eaten than wheat.

Page:38

If there were enough good food in every country every day for every person.

would the world be a better place than it is?

We say,"If there were enough food."not,"If there is enough food."because there is not enough, and we know it.

We say "If there were something in this hand you would see it,"because we know that there is nothing in the hand.

But with this hand,which is shut ,we say,"If there is something in this hand you will see it."

Now the hand is open.

There is something in it and you do see it.

Page:39

If we asked the question,

"If there were enough good food for everybody,would the world be a better place?"

some people would answer;

"Yes,the world would be a better place."

other would say:

"No,nobody would do any work!

The world would be a worse place."

And some others would say something like this;

"That is a strange question to ask when so many people in the world today do not get enough food.

There will be time to answer your question when we grown enough food for everybody."

What would your answer be?

Page:40

Why do people work?

Do they work only for their private needs

-because of their need for homes and food and clothing themselves and their families?

Why do some people work when they have enough of all these thing?

Do they work for pleasure,

because making things,for example,give them pleasure ?

Do some them work for the public good?

Why are some people happier when they are working?

Isn't work one of their needs?

Why do you work?

Do you need to work to be happy?

Do we know one another's needs?

Aren't we in the dark about some of them?
