THE ATLANTIC TELEGRAPH.

The Atlantic Telegraph and all that relates to It,—
the best kind of rope to be used, the best mews of get-
ting it down, and the best *ay to work it when it is
down,—the whole whams, in fad, seems to be slowly
drifting back again into thaws realms of theory and spe-
culation front which it his only so recently emerged
Already there are many competitors and prtjeotors in
the field, some to work the old rope, some to make a
new. It is not oheering to and tint public attention is
almost instinctively directed to the oonsideritim of the
latter project, and that to the hopes and esmotatlona

and with such risks—is greedy regarded its virivally lost

remedies for overcoming the difilmillies of the Atlantic,

Gorgon shells of the wet delicate texture, and so small

shells, even to their finest ridges, were uninjured, and
had evidently lain without movement in those tremen-

But a question arises with regard to rope-covered wire,
and, indeed, submarine cables of all kinds it laid et very

of the superineumbent MOM of water Weds the guMa•
