THE necessity for a liberal consideration of the question of water 
supply for the dry districts is of such rapidly increasing im- 
time has arrived for active steps to be taken to obtain, ual 
Survey and observation, the data necessary to determine the best 
Means to be adopted to conserve an tribute, in an economi 
little benefit on its course ; though running through districts 
where the soil only requires its invigorating agency to produce in 
growth suited to the climate. 
I.—Water supply for stock routes. 
.—Water supply for irrigation. 
This course is advisable for two reasons: because the works to 
be dealt with, that have up to the present time been carried out 
the Government, have been solely for the improvement of the 
Stock routes ; and because the important works necessary on these 
irrigation 
“annels, but such points might not be suited to the general divi- 
Sion of the watering stages along that route.
