This account of the laying of the 'second Atlantic cable has a special interest from its views and details of the ' Grt at 

 Eastern' steamship, which performed the work. The cable snapped in mid-ocean, and the enterprise was not carried to 

 a successful issue until the following year. 



The beautiful plates aftbrd an excellent idea of the technical part of the enterprise, the scenery of the Irish and 

 Newfoundland coasts, and the old-world aspect of the Agamemnon (which laid the 1858 cable) and the Great Eastern.
