THE SEAS NATURAL POWERS.-The sea
occupies three-ffths of the surface of the
earth. At the depth Of about $500 feet
waves are not felt. The temperature is the
same, varying only trifle from the ice of
the pole to the burning sun Of the equator.
a mile down the water has pressure OF
over ton to the square inch. If a box six
feet deep were filled with sea water and al
lowed to evaporate under the sun there
would be two inches of salt left on the bot
tom. Taking the average depth of the
ocean to be three miles, there would be a
layer of pure salt 230 feet thick on the bed
of the Atlantic. The water is colder at the
bottom than at the surface. In the many
bays on the coast of Norway the water often
freezes at the bottom before it does above.
Waves are very deceptive. TO look at
them in storm one would think the water
travelled. The water stays in the same place,
but the motion goes on. Sometimes in
storms these waves are forty feet high, and
travel fifty miles an hour-more than twice
as fast as the swiftest steamer. The distance
from valley to valley it is said is generally
fifteen times the height hence a wave five
feet high will extend over seventy-tive feet
of water. The force Of the sea dashing on
Bell Rock is said to be seventeen tons for
each square yard. Evaporation is Won
derful power in drawing the water from the
sea. Every year layer of entire sea, four
teen feet thick, is taken up into the clouds.
The winds bear their burden to the land,
and the water comes down in rain upon
the fields, to flow back at last through rivers.
The depth of the sea presents an interesting
problem. If the Atlantic were lowered
6,564 feet the distance from shore to shore
would be half as great, or 1,oO0 miles, say
1860 feet, there would be a road OF dry
land from Newfoundland to Ireland. This
is the plan on which the great Atlantic ca
bles were laid. The Mediterranean is COM
paratively shallow. A drying up Of G60
feet would leave three different seas, and
Africa would be Joined with Italy. The
British channel is more like pond, which
accounts for its choppy waves.
REASONS WHY THE BABY CAUSE.-THE
young bachelor who volunteered an opinion
as to the reason for a baby's smile, and the
summary Justice which he received at the
hands of the baby's nurse, are well known,
but why the baby cries is a matter as to
which few men have any curiosity, prOvld-
ed it is not too late to have an engagement
down town when the concert begins. The
"NIother's Manual of Children's Diseases"
explains the matter thus:
''Cries are the only language which a
young baby has to express its distress; as
smiles and laughter and merry antics tell,
without a word, its gladness. The baby
must be ill, is all that its cries tell one per-
son; another, who has seen much of sick
children, will gather from them more, and
will be able to judge whether its suffering
is in the head or stomach. The cries OF
baby with the stomach ache are long and
loud and passionate; it sheds profusion OF
tears; now stops for a moment, and then
begins again, drawing up its legs to its
stomach; and as the pain passes Oft, stretch
es them out again, and with many little
sobs passes off into quiet sleep. If it has
Inflammation of the chest, it does not cry
aloud, it sheds no tears, but every few min
utes especially after drawing deeper
breath than before, or after each short, hack
ing cough, it gives a little cry, which 1t
checks ap parently before it is half finished,
and this, either because it has no breath to
waste in cries, or because the effort makes
its breathing more painful. If disease is
going on in the head the child utters sharp,
piercing shrieks, and then, between whiles,
a low moan or wall, or perhaps no sound at
all, but lies quiet, apparently doing, till
pain wakes it up again."-Errhange.
