McCabe, James Dabney, 1842-1883

"Great Fortunes, and How They Were Made"


9. That more than four nautical miles of the Atlantic cable have
been recovered from a depth of over two miles, and that the
insulation of the gutta-percha covered wire was in no way whatever
impaired by the depth of water or the strains to which it had been
subjected by lifting and passing through the hauling-in apparatus.
10. That the cable of 1865, owing to the improvements introduced
into the manufacture of the gutta-percha core, was more than one
hundred times better insulated than cables made in 1858, then
considered perfect and still working.
11. That the electrical testing can be conducted with such unerring
accuracy as to enable the electricians to discover the existence of
a fault immediately after its production or development, and very
quickly to ascertain its position in the cable.
12. That with a steam-engine attached to the paying-out machinery,
should a fault be discovered on board whilst laying the cable, it
is possible that it might be recovered before it had reached the
bottom of the Atlantic, and repaired at once.
