IRRIGATION IN UPPER INDIA. 147 
recently appeared in the Sydney Morning Herald, none of the 
writers seemed to be aware that the consideration of the irrigation 
question in New South Wales was warmly advocated many years 
ago by Mr. Bennett, Engineer-in-Chief for Roads and Brid : 
and that Mr. Moriarty, Engineer-in-Chief for Harbours and Rivers, 
© many years ago not only advocated the consideration of the 
question, but took most important action in the matter. The 
result of that action is, that at the present time the elaborate sur- 
veys, cross sections, and statements of discharges of the Murray, 
the Murrumbidgee, and the Darling, which Mr. Moriarty had 
then prepared contain the most valuable information in existence 
garding the possibility of carrying out irrigation works on an 
extensive scale with those rivers as the sources of supply. 
inquiry into the prospects of irrigation in Victoria has been 
dealt with exhaustively by Mr. George Gordon. Some months 
ago that gentleman also prepared a valuable report on proposed 
improvements in the Darling, and when doing so had the benefit 
of the survey maps of that river which had been made under Mr. 
Moriarty’s direction, and which were on this occasion specially lent 
under official sanction. As the public does not seem to be well- 
informed as to what is being done in the matter of irrigation, it 
may be mentioned that at the present time Mr. Bennett, as 
Engineer-in-Chief for sewerage works, is preparing land and having 
works carried out for sewage irrigation. ts 
n connection with the introduction of irrigation into New 
South Wales, the question of evaporation has received much 
maximum evaporation registered at Roorkee, with a hot wind 
blowing continuously, was half an inch in twenty-four hours. From
