moisture that heat has drawn up from tn,
ocean and rivers into clouds, and sent dow
again on earth in fogs, dews, rains, and va

our friend, the lamb, and prepared by hin

than YOU"
Wonder how You know so much about
it," remarked his mother.
Lamb, peas, etc.," continued Jack
calmly, are ground and sifted in the
stomach's mill. The albumen is taken to
your body. The oils and starch are just 80
much coal. They are dissolved, and re-
solved. and heaven knows what all, till they
reach the lungs, where they join with the
oxygen that you breathe from the air, and
burn like that fire" pointing to the range.
Z" So you see my bill of fare was correct.
Oxygen, hydrogen"
Now, Jack, will you stop7"
And as there must be some latent heat
also, suppose may add that we had bit
of the sun for dinner"
Jack, 1 call it wicked to talk ike that. -
Wicked! call it grand! sublime! Just
see how simple and beautiful it looks beside
the clumsy old theories about squeezing out
heat, and force being lost and destroyed
every time that it is used. We know that
God gave the sun his heat, though we can
not tell how it is made. This heat leaves
the sun as light. 1t enters the air as heat
and gives it motion. The heated air grows
larger and lighter and rises; the cold air
drops down in its place, and SO we have the
trade winds. Light enters the water as
heat. The heat gives it motion, something
as it does in your tea-kettie. The water
atoms are pulled apart, grow light, and rise
in vapor, which soon huddles together in
clouds and falls again in rain, which feeds
the streams that drive our mills. Heat
stores in plants the nourishment of animals
and men. This nourishment gives out heat,
which becomes force till we use it, when it
once more turns to heat, or, perhaps, into
another form of motion that we call sound. -
Is the boy crazy I" inquired his mother.
apparently of the tall candlesticks on the
Not at all,n returned Jack. quietly.
"sound is motion, as you could easily
prove for yourself. Make a rod Fastened
at one end, and with a bright bead at the
free end) vibrate, SO that its shadow shall
fall on a white screen. Each vibration, as
it sings its little note, will make ripples
the vibrations the shriiler the note It viii
sing, and the deeper will be the curves
and ripples. Scatter sand over a metal
plate, and draw violin bow across the
edge of the plate, and the sand will fall in
to the most beautiful figures; and the
figures. Each note has it's own particular
markings !; it's picture, SO to speak, which
proves that sound is motion, and music is
a regular, even motion"
"Well," said Jacks mother, drawing a
long breath, 81 am glad there are some |
everyday things left that haven't any his
tories or any explanations, and that 10hody |
can make out any different from Whist they
used to be-"
"Sure of that, mother ~ asked Jack ro-

WELL" replied his mother, deliberately
looking about the room. "Well, there is
the clock. That is old-fashioned enough,
and there is nothing to say about that. 1t
goes, and that is all you can say about it."
~ can say one thing more" retorted
to keep up such q ticking and creaking |
when all the time it is running on your
force"
my forcer
"Certainly. 1t ticks the whole eight
days on the strength Of your arm, that you |
put into it when you wound it up, and the |
only reason it is SO long in using up it's
to the pendulum, and the friction of the |
machinery. You need not look SO unbeliev-
ing, mother. You have been doing your
own time-keeping for the last twenty years,
for all you keep clock"
"WeL, never!" murmured his mother
" If had known that had that RESPONSE
bility, added to all my other cares, really
believe / should have sunk under it,
"Why that is nothing to the other won~
derful results that you are all the time ac-
complishing. When you speak you literally
cut and carve the air into waves. And as |
these waves roll on outward, long after we
have done hearing them, you may be said
to alter the whole air. And when you lift
up the clothes-line, OF tilt Maggie's see-saw,
you have altered the earth's centre of |
gravity and sent a shock through the whole |
planetary system Now travelling forty
miles an hour, it would require more than
two hundred and seventy years to get to
the sun !; so call that having an extended
influence" concluded Jack, roguishly.
His mother bridled.
This is very entertaining. Pray 60 on,
