**BARREN JACK.” 15 
Cod, these being transported with the overflow from the ponds 
of Sir Terence Aubrey Murray, at Collector, this gentleman 
having stocked his ponds from the Murrumbidgee River. As 
a result of this introduction, the Murray Cod became firmly 
established in the waters of Lake George, multiplying to a 
remarkable extent, and growing rapidly, so that a few years 
later, and for many years, a regular fishery was carried on, 
many tons being captured and sold. 
The successful results accruing to this fortuitous introduction 
of Murray Cod open to our view the great possibilities of this 
fish in its relation to our future food-supply, more especially 
in view of the trend of recent events. During the last few 
years there has been a great movement in New South Wales 
in favor of artificial conservation of water on a large scale 
and by means of giant dams, the waters so impounded to be 
used in irrigation for general agricultural purposes. This 
movement has, to some extent, materialised, and there is 
in course of construction at the present time, and at a locality 
in southern New South Wales known as “ Barren Jack,” a 
huge dam which will hold back an enormous body of water. 
This dani is being thrown across the course of the Murrum- 
bidgee River, at a short distance below its junction with the 
Goodradigbee River. Though there can be little doubt that 
this work will be more than amply paid for by the added 
agricultural value which will be given to the hundreds of 
square miles of fine arable land stretching away at its foot, 
its value from a fisheries standpoint is not to be lightly passed 
over. As the latter aspect of the case is so important, and as 
it has not hitherto been discussed, I feel constrained to go 
into a few details here, especially in view of the fact that it 
is contemplated by many that other works of a somewhat 
similar nature will be undertaken in the near future. 
It is calculated that the Barren Jack Dam will impound 
at normal levels a quantity of 33,612,671,000 cubic feet, or 
210,079,193,7774 gallons of water, which will be confined in 
a surface area of 12,784 acres. Out of this vast area there 
will be 8,246 acres of 30 feet and less in depth. I might
