as a piece of coal. Q. When they are polished, do they look nice? A.
Yes; so bright you can see your face in them. Q. What is this wood
called? A. Bog-oak. Q. Will you all try to remember this lesson? A.
We will. Teacher. That is right; for little children should always
remember the pretty things that their teacher takes such trouble to
tell them.

In places where coal is most burned, a piece of it may be made the
medium of a very useful and instructive lesson, being so familiar an
object, their attention will be arrested by its being made the subject
of a lesson; and their curiosity aroused to know every thing about
it. When the teacher asks what is this, the simultaneous shout, of
"a piece of coal," will convince him that he has arrested their
attention; and a few questions will exhaust their stock of information
on the subject--they will tell him its uses are to make fires to boil
up their dinners, &c. &c. He may then proceed as follows:--You see,
little children, this piece of coal; look at it attentively; it is
black and shining; and you all know will burn very quickly. The places
from whence all coal is brought are called _coal mines_; the men who
dig it out of the ground, and the ships that carry it over the sea,
are called colliers, and the place where the coals are got is called
a colliery. The coal mines are deep holes made very far under the
ground, in order to get at the coal; some of them go under the sea.
The colliers live a great part of their life, in those dark holes,
in order to get us coal to make us fires to dress our food, and very
often are killed, either by the falling in of the roof from above, or
from a sort of air called fire-damp, which, if touched with any fire,
will blow up like gunpowder, and will kill any person that is near it;
the poor colliers are also often smothered by the bad air that is in
those damp, dark holes; so you see, little children, what dangers they
go through, in order to get us coal, which we could very badly do
without.

How very good God is to us; he made this coal under the earth that we
might have nice fires to dress our food, and warm ourselves by in
cold weather; we should be very thankful to him for all his great
blessings, and should never do anything to make him angry with us; he
is very sorry when he sees a little child naughty, because he has done
every thing to make us happy, and we never can be so if we are naughty
and bad. Bad boys and girls are never h
