The area of New Zealand is 50,000 acres less than the area of Great 
Britain and Ireland ; the Northern Island is 1-32nd smaller than England ; 
the Middle Island is l-9th smaller than England and Scotland combined ; 
50,000,000 acres, or 2-3rds, of which are estimated lit for agriculture ; the 
rest is made up of impassable mountains, sand-flats, swamps, lakes, and 
rivers . — (Vide “ New Zealand,” by J. v. Hochstetter.)
