The abnormal quantity of rain that fell in 1849 upon the 

 same area was nearly 56 per cent, more than the quantities 

 here stated, the total quantity in that year being 958,029,539 

 gallons, being the greatest quantity that has fallen in any 

 one year since correct meteorological records were kept in 

 Victoria. 



The Elizabeth-street sewer, marked A, has its source (as 

 will be seen upon the plan now submitted) on the roadway 

 between the north end of the University grounds and the 

 new Cemetery, at a distance of two miles and 15 chains 

 (along its course) from the point where it discharges into 

 the Yarra Yarra below the falls, the entire area drained by 

 this channel being 530"35 acres. 



The area drained by the channel in Swanston-street, 

 marked B, is 248*2 acres. The source of supply at the 

 greatest distance from the outlet is at a point in Lygon- 

 street, between Grattan and Faraday-streets, 1J mile from 

 the point at which it falls into the Yarra at Prince's Bridge. 



The area drained by the channel marked C at the west 

 end of Little Bourke-street, receives the drainage of 98 acres ; 

 the greatest length traversed being 58 chains. 



The water from this channel is discharged into a circular 

 sewer built of brick, 3 feet 3 inches in internal diameter, 

 and passes underneath the station ground of the Victorian 

 Railways into Batman's Swamp. This culvert is now being 

 considerably lengthened, in order to convey the water under 

 the new station ground made by the removal of Batman's 

 Hill. On account of Spencer-street being sometimes flooded, 

 it has given rise to an erroneous impression that the culvert 

 is too small to carry off the water, but the real reason is, 

 that the grating at the mouth has frequently been partially 

 closed, and the whole storm-water not being able to enter, 

 it, as a matter of course, soon covered the street. This can
