Large cavities are found in some of the stones in the
pyramids, which may have been worn by the foot of a derrick turning in
them. That there were enormous numbers of men employed in the building
of these ancient structures is well known; these results of their
great aggregated strength we see, but they left no record of the means
by which this strength was focused and brought most effectually to
bear on their mighty tasks.
THE FIRST ATLANTIC CABLE.--As early as 1842 Professor Morse declared a
submarine cable connection between America and Europe to be among the
possibilities, but no attempt toward this great achievement was made
until 1854, when Cyrus Field established a company, which secured
the right of landing cables in Newfoundland for fifty years. In 1858
soundings between Ireland and Newfoundland were completed, showing
a maximum depth of 4,400 meters. Having succeeded in laying a
cable between Nova Scotia and Newfoundland, Mr. Field secured the
co-operation of English capitalists in his enterprise. The laying
of the cable was begun August 7, 1857, from the port of Valencia,
Ireland, but on the third day it broke, and the expedition had to
return. Early in the following year another attempt was made.
The cable was laid from both ends at the same time, was joined in
mid-ocean, but in lowering it was broken. Again, in the same year, the
attempt was made, and this time connection was successfully made. The
first message over the line was sent August 7, 1858.
