EARTH.

What is that element on which we tread!
What properties may you readily discern in it

Has it firmness? Has it weight? Is it lucid or opaque ?

Is it easily put in motion, like the air and water?

Does water appear to dissolve it? Or fire to consume it?

What use do you perceive in the solidity of the earth ?

Could we walk, or build upon an unstable element?

Do you know how many kinds of earthy substances there are? There are said to be nine primitive kinds of earth :-tell me the most common earths.

Are different kinds of earth found in combination with each other?

The different combinations of earths upon the surface of the globe, are for the most part mixed with vegetable matter; by what general name do we designate these diversified earths ?

In what relation is the word soil chiefly used ? Enumerate some of the different kinds of soil. Have all the earths and soils an use? What kind of earth has a white colour? And what are its properties? What has a yellow colour? What kind of soil has a dark colour?

Are all soils equally productive ?

What kinds of earth are used for bricks? For mortar ? For pottery and china ? What is the chief kind employed in making glass?

Are any kinds useful in medicine? In painting?

Does the earth contain combustibles ?

If we dig into the earth, what do we find ?

We find layers, or strata of different kinds : do we know all the different strata which lie beneath the surface of the earth? Why not?

What are the productions called which are found within the earth ? [Minerals: under which general name we may comprehend fossils, earths, or earthy minerals, metals, precious stones.]

What are the productions on the earth's surface called?

Under what principal classes may its vegetable productions be arranged?

What creatures live upon, or inhabit the earth?

What is the noblest creature that inhabits the earth?

Whence do living creatures derive their nourishment ?

Whence does man derive his nourishment?

What is required of man, in order that the earth may yield to him its fruits?

D 2

What is the great cause of the necessity for man's labour ? Gen. iii. 17-19.

But does the earth yield no kind of productions without labour? If it depended upon our industry to have grass and trees, and many different kinds of plants, would all our wants be supplied ?

Whose power and goodness constantly provides a succession of the productions of the earth ? . "Who prospers the labour of

man,

and converts it into a moral blessing?

What relation have our bodies to the earth?

And how is the connection to be dissolved ? ,We hare considered a little of the nature of earth ; we have named different kinds of earth; some of the productions contained within the earth, and some of those which belong to its surface. We have mentioned the earth as a habitation for man-now consider what relation the earth bears to the other parts of creation. *

What is its place in the universe ?
What do we know with respect to its time?
Who is its Creator and Preserver ?

. We have confined ourselves to a very few general considerations.--The Instructor might touch upon the natural geography of the earth, its seas, continents, islands, &c. its mountains and rivers, diversities of climate, the natural productions of each country.--He might give a general idea of the size and form of the earth, its annual aud diurnal motion, &c.—These subjects are particularly treated in many works for the instruction of young persons.

In what state was it created ?

Where do you read of the creation of the earth, and of its productions ?

And what did God say when He beheld all that He had made ? [Gen. i. 31.]

What great changes have taken place on the earth?

What is the first change of which we read?

Are the consequences of this change still manifest?

What was the second change?
To what are both these changes owing ?

Are any of the consequences of the deluge to be perceived ? How?

What third change do we expect ?

What will take place at the end of the time of the earth?

Read 2 Pet. iii. 10; and Rev. xxi. l.

Will then all our possessions upon earth be destroyed ?

What use should we make of this consideration ? What does our Saviour say, Matt. xxiv. 35-42. Compare this with Matt. vi. 19-21.

And ought our affections to be set upon a world which is corrupted by the sin of man, and which is to be dissolved by fire! [1 John ii. 15-17.]

Let us seriously apply to ourselves the words in the 2d Epistle of St. Peter.-" Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness."

* The Instructor, in considering the busk, might refer to the comparison, Ps. i. 4 ; and Matt. iii. 12. He might contrast the value of the body with that of the soul. (Matt. xvi. 26.)
