Note 225 — Chapter XXI · Fundamental Laws of Socialistic Society.
Meta Stern Lilienthal translation
During the fifties of the last century, the sailing vessels took about six weeks to reach New York. The steamers crossed in two weeks. During the nineties, the voyage was made in a week, and now it is made in 5½ days. As a result of this progress, the two continents are brought nearer to each other now than Berlin and Vienna were a century ago.
