PRESIDENTIAL ADDRESS. 41 
Supplies of artesian water are struck at a moderate depth, 
while the Bogan River is outside of that area. 
If the utmost use is to be made of the Macquarie waters 
in average and dry seasons, it will be necessary to con- 
struct a continuous series of weirs in the Macquarie channel 
between the Warren Weir and the Barwon to retain water 
for stock purposes; it may be necessary to provide for 
filling those below the Macquarie Marshes from artesian 
bores. Those above would always be filled by the river 
flow, sufficient water would then be diverted for the supply 
of the Gunningbar, Duck and Warren Creeks; and the 
Bogan River, which are situated outside of the artesian 
area, and have no record sources of supply. 
The works constructed in the Macquarie consist of diver- 
sions down the Hwenmar, Belaringar, Gunningbar, Duck 
and Crooked Creeks with the weirs for this purpose in the 
river at Gin Gin and above Warren. It is not proposed to 
construct any further diversions. 
The remainder of the tributary streams of the Darling 
traverse the artesian area, the country becoming rapidly 
less arid in an easterly direction, and increasing in aridity 
to the west. The works constructed up to the present on 
the easterly stream consist of diversions from the main into 
effiuent channels for stock purposes; the surplus water in 
every case flowing intothe Barwon. These works consist 
of a cutting from the Big River into the Meei, via the 
Greenbah Creek, a cutting from the Meei into the Moomin 
Creek with a weir in the Meei. Itis proposed, in addition, 
to make a cutting at the bifurcation of the Meei and Big 
River. A cutting from the Big River into the Carore 
Creek, a cutting from the Moomin into the Thalaba Creek, 
a cutting from the Namoi into the Gunidgera and Pian 
Creeks, with a weir in the Namoi below Wee Waa. When 
stock purposes have been served, the remainder of the flow
