Students in 9th grade are learning about the new technologies in communication and travel that occurred during the 19th century.
One of the most interesting stories is the epic task of laying the transatlantic cable across the ocean. It was an elaborate process.
The first cable worked for a few months and then the insulation was compromised.
The second cable broke midway in 1865.
In Jules Verne's classic Novel Twenty Thousand Leagues Below the Sea, Captain Nemo sees the cables lying on the ocean floor.
