This is for the upper bracket of this age group -- the lower bracket of the next. The story of a girl of about 15 whose father was a sea captain in the adventurous days when reaching the California seacoast meant sailing round the Horn. He kidnapped his own daughter from the sacred precincts of Beacon Hill -- and she was catapulted into the midst of the exciting days of the transfer of jurisdiction of California from Mexico to the United States. A glimpse of Fremont -- a friendly picture of General Kearny -- a not so friendly one of Stockton -- a glamorous visit to a Spanish Hacienda -- all in all a satisfying book. Ada Darby has the faculty of making her history seem incidental -- her story paramount.
