For the young man whose eyes turn seaward, there is much rewarding reading in Mr. O'Brien's adventure story of Johnno Brown who sails a clipper ship as apprentice to the captain. In each port, be it Zanzibar, Bombay, Singapore, Mombasa or Durban, Johnno encounters new adventure. There is no time for recuperation aboard ship either, for here, what with storms at sea, pirates and sundry exploits, the pitch maintains its high level. Also provided is a vivid picture of the duties and the general life aboard a clipper ship. This is well written with more than a sprinkling of sea language.
