“ The ship will, however, sooner or later require a higher rate of freight for ports of slow despatch, and this increased expense in transport will undoubtedly operate in favour of rival ports. For the ports themselves are but stepping-stones to or from a market or industrial centre, and the market will always select the cheapest route for its trade. With the increase of populations in the Old World and the development of new countries, the transport of emigrants and of travellers for business and for pleasure became a highly important and lucrative source of employment for steam shipping. ”
