“ Between the freight cargo, and the correspondence which controls it there is a great difference. Rapid transport of letters, intelligence, and passengers, and leisure transport of freight, is the law of nature, and to attempt to reverse it is but to attempt that which will never be successfully done, simply because wholly unnecessary in any permanent economic sense. And not only is higher speed than that of clippers unnecessary in ordinary freight transport, but it is clearly impossible in any normal condition of trade. ”
