PORT JACKSON. — The Light-house, or Macquarie Tow- 
er, is in latitude 33° 51' 11" South, and longitude 4' 29"*8 
East of Sir Thomas Brisbane’s Observatory at Sydney, or 
151° 19' 45" East of Greenwich. It is a revolving light, 
and may be seen at the distance of ten leagues. The Inner 
South Head bears from it N. 20° W.*, and is distant about 
two thousand five hundred yards. The North Head bears from 
the Inner South Head N. 53° E. by compass, about two thou- 
sand four hundred and forty yards ; and the narrowest part 
of the entrance, which is between the Inner North and South 
Heads, is a little more than eight hundred yards, so that 
there is abundance of room to work in should the wind blow 
out of the Port. On arriving off the light-house, steer in 
between the North and South Heads until you are past the line 
of bearing of the Outer North, and the Inner South Heads: 
then haul round the latter, but avoid a reef of rocks that 
extends for two hundred yards off the point, and steer for 
Middle Head, a projecting cliff at the bottom of the bay, 
until the harbour opens round the Inner South Head ; you 
may then pass on either side of the Sow and Pigs ; but the 
eastern channel, although the narrowest, is perhaps the best; 
but this, in a great measure, depends upon the direction of 
the wind. The eastern channel is the deepest. The Sow 
and Pigs, or Middle Ground, is the only danger in Port 
Jackson : — it is a bank of sand and rocks, of about eight 
hundred yards in length, by about three hundred and fifty in 
* All the bearings that are used in these directions are by com- 
pass, unless when otherwise described.
