AsYsMAL DEPTHS OF THE SEA

Beauties Revealed by the Slime at the Bot
tom of the Ocean.
The new submarine world now ex
plored and mapped out presents a very
different picture from that painted for
us by the poets. But a short time has
elapsed since the bottom of the ocean
was supposed to be the counterpart Of
the face of the earth above water-with
hil lls and valley, with PERCEPTIONS noun
tains lifting toward the surface and
profound Rorges sinking to unfathom-
able depths. The ocean floor is far
less diversified than the land. Here
and there, to be sure, islands in mid
ocean are the SUBMITS of enormous
mountains, rising more or less alb
ruptly from generally level sur
face, and the sea lying over
narrow, depressed region in
northwestern Pacific reaches its great.
est depth. But this is exceptional; in
its general character the ocean bottom
consists of vast fiat or slightly un-
dulating plains. An extraordinary cir
cumstance that has been noticed with
interest, and that always creates sur
prise when first learned, is the entire
absence of foreign matters in the
deeper part of the oceans floor OF all
The vessels lost in midocean, of all the
human beings that have been drowned,
Of all the marine animals that have
perished, of all the clay, sand and
gravel let fall by dissolving icebergs, of
all the various substances drifted from
every shore by shifting currents-nota

from one Thousand to two thousand five
hundred fathoms in depth covers the uni
form deposit of thick blush, tenacious
slime, called globigerina ooze. A bit
of this under powerful lens Is a reve-
lation of beauty not readily forgotten
The ooze is composed almost entirely
of the daintiest, most delicately beau
tiful shells imaginable. At depths
greater than twenty-five hundred
fathoms the bottom of the sea consist
mainly of products arising from eX-
pcsure for almost incalculable periods,
TO the chemical action of sea water, of
pumice and other volcanic matters
This finally results in the formation of
the red clay deposits that are consid-
cred characteristic of the profoundest

| lime, which in the form of the shells of
| foraminifera, makes up so large part
Of the giobigepina ooze, is here almost
entirely absent. Sea water is very
nearly universal solvent, and before
any shell, large or small, reaches the
| bottom of these tremendous abysms it
is chemically eaten up, literally dis

pressure of the water must materially
