WATER CONSERVATION, IRRIGATION AND DRAINAGE IN N.S.W. 231 



observed that there were some granite outcrops in the part of the 

 district lying to the northward of a line joining Mulwala and 

 Tocumwal. Although to the eye there seemed to be no extensive 

 elevation of the land, it was considered probable that the levels 

 would show local rises near these outcrops. The effect of the 

 presence of these outcrops proved much greater than was antici- 

 pated. The levels show that the contours are materially affected 

 throughout an area equal to a circle of about eighteen miles in 

 diameter. Within this area the land in one place reaches a height 

 of 167 feet above the adjacent plains, and in another a height of 

 150 feet. This area approximates roughly to circular in form, 

 but a line from Berrigan to Mulwala would pass through its 

 greatest length which is about twenty miles. 



General uniformity of the district. — Leaving out this portion 

 of the district, the levels show that from about the western 

 boundary of the County of Hume, the contours are very regular 

 and show a gradually diminishing fall in a westerly direction ; 

 but in some places, and particularly when approaching Jerilderie, 

 the direction of maximum fall is north-westerly. So far as the 

 levels are concerned, it is quite practicable to take off branch 

 canals to Tocumwal and Deniliquin on the south side and to 

 Tirana, Jerilderie, Conargo, and Wangonilla on the north side. 

 The delivery of the water on the land by gravitation could begin 

 about forty miles above Berrigan. From that town onward it can 

 be delivered throughout the entire district. 



The importance oj the project not realised. — Although many of 

 the residents of the district which would be directly benefited by 

 the proposed Murray River Canal naturally take great interest in 

 the subject, few, if any, of them even approximately realize the 

 magnitude and value of the project. It may perhaps put the 

 question in a clearer light if its capabilities be compared with some 

 existing arrangements for supplying water. 



Illustration of the value of the project.- — It is well known that 

 in Riverina as well as in other parts of the State, pumping engines
