Work and Receipts OF the French Atlantic

The disposition Of the public to Fay attention to
Geographic enterprises is attended by the usual re-

but the events OF 1866 are not yet sufficiently remote
to admit OF the prospect Of danger. The French

doubted but much further experience Will be ne

direction can be ventured upon 1t is affirmed on
good authority that during the last eightee years
there have been eight thousand miles Of light cable
laid, some covered with light wre two consisting Of

hemp and other substances, but that no line OF this
description has been found to last longer than one
year. while IN some cases the period has been few
weeks only. All the cables now IN working order
are OF the strong and heavy form, ana there seems
no example or any kind that be cited TO justify
the adoption OF the light principle.
