were covered with tiny drops of water which sparkled in the sun.

The dew last night was like a little shower. It watered the thirsty plants, and made them fresh and sweet for us. In a short time the sparkling dew was gone. What became of it? Surely the plants did not drink all the dew.

What is dew? From what does dew come? Let us see if we can find out. Here is a pitcher the outside of which is dry.

Watch closely as Ray fills the

pitcher with ice-water.

What do you see?

The outside of the pitcher is covered

with fine water-dust.

Now the water

dust is forming into little drops which grow larger and larger. See how the water trickles down the side.

Put your hand on the pitcher. How does the surface feel?

It is cold. It is very cold.

What does this cold surface do to the air that surrounds it?

It cools the air. The cold changes the vapor in the air to water-dust and then into water-drops.

Cold air changes vapor to water.

Breathe on this glass, Jessie. What do you see?

From what did the water-drops come? The cold glass changed the vapor in my warm breath to water.

Sometimes you see drops of water form on the window-panes. Why does water form into drops there? Tell where you have seen water-dust form from vapor. From what does dew come?

Does it come from the vapor in the air, Miss Stone?

Certainly it does. Dew forms on the grass, leaves, and flowers just as drops of water form on the outside of the pitcher.

During the day the sun warms the grass, leaves, and flowers.

The sun heats the whole surface of the ground. After the sun goes out of sight, the grass, leaves, and flowers lose some of the heat which the sun gives them.

Soon the ground becomes so cold that it chills the air and changes the vapor into water. Sometimes the grass, leaves, and flowers cool very rapidly. Then they become very wet.

In the morning we say there was a heavy dew last night.

If the surface of the ground cools slowly then very little dew forms. Can you tell why?

Sometimes there is not much vapor in the air. Will dew form then?

If there is much vapor in the air, and the surface of the ground cools rapidly, there will be a heavy dew.

If it is cold enough to freeze, dew becomes frost.

Frost is as white as snow. On the grass, leaves, and flowers it looks like needles of ice.

What is dew? Does dew fall?

Tell how dew forms on the grass, leaves, and flowers.

Where will one see the more dew, on the grass or on the bare ground? Why? Will more dew form under a tree than near it?

"A million little diamonds

Twinkled on the trees,

And all the little maidens said,

เ

A jewel, if you please!'

But when they held their hands out

stretched

To catch the diamonds gay,

A million little sunbeams came

And stole them all away."

JACK FROST'S LITTLE SISTER.

This morning, as soon as the rest had gone down,

I stood by the window to see

The beautiful pictures which there in the night

Jack Frost had been making for me.

"There were mountains and windmills, bridges and boats;

Some queer looking houses and trees; A hammock that swung by itself in the air,

And a giant cut off at the knees.

"Then there was a steeple so crooked and high,

I was thinking it surely would fall, When right down below it, I happened

to spy

The loveliest thing of them all.

"Would you think it? right there was a dear little girl;
