rainfall over the area 
within that State, the 
station showing the 
greatest rainfall be- 
ing Toowoomba on 
the north-eastern 
fringe of the catch- 
ment. With regard 
to the portion lying 
between the northern 
boundary of New 
South Wales and the 
town of Bourke on 
the Darling River, 
the rainfall has been 
based on the mean of

on the balance of the 
catchment lying be- 
tween Bourke and 
Wilcannia has been 
compiled bytheauthor 
from the observations 
of a large number of 
stations supplied by 
the Meteorological 
Department of this 
State. The formula 
adopted in computing 
the mean precipita- 
tion over the whole 
of the gathering 
grounds, is identical 
with that adopted in
