What is called the shore-end of the cable--_i.e._, that part nearest
the shore, which is thicker than the rest--was first laid by a smaller
steamer. It extended from Valentia to a point twenty-eight miles at
sea. Here it was buoyed, until the great ship arrived. On a wet day in
July, 1866, it was joined with the main cable on board the "Great
Eastern," and on the same day that vessel started on her voyage to
Newfoundland.

It may seem a simple matter to distribute or "pay out" the cable, but
in practice it is exceedingly difficult. Twenty men are stationed in
the tank from which it is issuing, each dressed in a canvas suit,
without pockets, and in boots without nails. Their duty is to ease each
coil as it passes out of the tank, and to give notice of the marks
painted on the cable one mile apart. Near the entrance of the tank it
runs over a grooved wheel and along an iron trough until it reaches
that part of the deck where the "paying out" machine is placed. The
latter consists of six grooved wheels, each provided with a smaller
wheel, called a "jockey," placed against the upper side of the groove
so as to press against the cable as it goes through, and retard or help
its progress. These six wheels and their jockeys are themselves
controlled by brakes, and after it has been embraced by them the cable
winds round a "drum" four times. The drum is another wheel, four feet
