9. It does not appear that he listened at keyholes, or, at least, that he was caught at it. In short, when you have penetrated through all the circles of power and splendor, you were not dealing with a gentleman at last, but with an impostor and a rogue; and he fully deserves the epithet of a sort of Scamp Jupiter.

III. To which class of composition does this piece belong? (See Definition 19.) Emerson is fond of short and pithy sentences rounded like bullets: point out examples. Point out also examples in the extract from Napoleon.

63.- Golden Thoughts.

[TEACHER'S NOTE. It is suggested as a profitable exercise, that to each pupil be assigned one of these "Golden Thoughts," to be memorized, and that the class be called on to repeat the couplets and stanzas, each the "Thought" assigned him.]

1. Count that day lost whose low-descending sun Views from thy hand no worthy action done.

2. Howe'er it be, it seems to me,

"Tis only noble to be good.

Kind hearts are more than coronets,

And simple faith than Norman blood.

3. Were I so tall to reach the pole, Or grasp the ocean in my span, I must be measured by my soul:

The mind's the standard of the man.

4. The heights by great men reached and kept
Were not attained by sudden flight;
But they, while their companions slept,
Were toiling upward in the night.

5. Small service is true service while it lasts;
Of friends, however humble, scorn not one:
The daisy, by the shadow that it casts,

In the lexicon of youth, which Fate reserves
For a bright manhood, there's no such word
As-fail.

7. He prayeth well who loveth well

Both man, and bird, and beast;

To hide the fault I see;

That mercy I to others show,
That mercy show to me.

THE WINDS.

māk ́ing, moving, tending.

pāçe, rate of motion.

spent, worn-out, exhausted.

1. How is it that the wind blows? What makes the air move?

You know the globe, the model of our earth. I dare say there is one in the schoolroom. You know the two poles, the north pole and the south pole, where it is always cold winter. You know the equator, between the two tropics, where it is always hot summer.

2. Now, remember that hot air is lighter than cold air: for hot air expands, that is, swells, and spreads its atoms apart, and becomes more spongy the hotter it grows; while cold air contracts, that is, shrinks, and closes its atoms together, and becomes more solid the colder it grows.

3. But if hot air is lighter than cold, then the hotter it is the more it must rise into the sky, if it can; and the colder it is the more it must sink toward the earth. In the hot tropics the air must be always swelling and rising, while at the cold poles it must be always shrinking and falling. And what will happen then? The hot air from the tropics must. always be flowing northward to the north pole, and southward toward the south pole, to fill up the space

which the cold air leaves empty when it shrinks. For air, like water, is always ready to flow in wherever it finds a vacant space.

4. And so, if the earth stood still, there would be a wind always rushing towards the north pole, and another wind always making towards the south pole. But there must be more than that. If only that went on, all the air would soon get to the poles; there would be too much air at the poles, and too little at the tropics. Therefore the air from the poles rushes back to the tropics, to fill up the space left empty there.

5. You have seen the same thing happen a thousand times. Why does the cold air, if there be a fire in the room, stream in through an open window or through a crack, and so make a draught? Because the fire heats the air in the room; and it becomes light, and flies away up the chimney, as the light hot air does towards the poles. But that leaves too little air in the room; and so the cold air rushes in through the keyhole, and under the doors, just as the cold air rushes from the poles to the tropics.

6. The mere difference of heat between the tropics and the poles would make two winds, even if the earth stood still. But the earth does not stand still. It turns round on its axis once every twenty-four hours; and thus the course of the winds is altered, and, instead of blowing due north and south, they blow generally northeast and southwest.

7. You all know that when you are traveling in a

carriage your body is moving on with the same speed as the carriage, and keeps that speed if you jump out, till you touch the ground, and are stopped suddenly by it: so that, if you jump out forward, the speed which your body has caught from the carriage will throw you on your face if you do not take care; while if you jump out backward the same speed will throw you on your back, and has stunned many a foolish person ere now by a tremendous blow on the back of his head.

8. Now, let us apply that same law to the air at the tropics. The earth there is 24,900 miles round, and it turns round once every twenty-four hours, from west to east. Now divide 24,900 by 24. What have you? 1,037 miles. Therefore every little atom of air at the tropics is going eastward with the earth at the rate of more than a thousand miles an hour. But as the air travels north the earth's circumference grows smaller.

9. This you may prove for yourselves by measuring on the globe. But as it all turns round in the same time, twenty-four hours, each spot on the globe is turning more slowly, the farther north it is. Look, for instance, at St. Petersburg in Russia. There it is only about half as far around the earth from east to west as it is in the tropics: so that St. Petersburg is moving eastward only half as fast as a point on the equator moves.

10. But the hot air from the equator keeps up to something of that tremendous pace of a thousand miles an hour eastward with which it started; and when it
