GREAT STEAMERS.


The _Brooklyn Eagle_ gives a very interesting description of the three
new steamships now almost completed and shortly to be placed in the New
York and Liverpool trade by the Cunard, Inman, and Williams and Guion
lines. The writer has prepared a table comparing the three vessels
with each other and with the Great Eastern, the only ship of greater
dimensions ever built. We give as much of the article as our space will
allow, and regret that we have not the room to give it entire:
