INTRODUCTION. 
The town of Albany is situated on the northern side of 
Princess Royal Harbour. This harbour is an almost completely 
land-locked body of water about five miles long from north-west to 
south-east, and about two and a half miles in width, which at its 
eastern end connects with King George’s Sound by a narrow 
channel. Much of the country surroim<ling Princess Royal Har- 
bour is of a rugged and broken character, rising into high rounded 
domes and ridges of granite on the northern .side, and into a 
prominent serrated ridge of granite and the rock known as 
"coastal limestone” on the southern. This latter ridge separates 
the waters of the harbour from those of the open ocean. (PL L). 
King George’s Sound is a large sheet of water almost land- 
locked on three sides, hut open on the east to the f'cean. It is 
connected at its western end with Princess Royal flarbour, and 
at its north-w^estern corner with the estuary known as Oyster
