32 NOTES ON FLOODS IN THE BRISBANE RIVER. 



Considering the small value of the sewage, 2d. per ton at the 

 most, and seeing, moreover, that its chief manm-ial value lies in 

 its soluble constituents, it is not probable that any mode of 

 abstracting from it a marketable manure can be devised. The 

 only possibility is that the pr(!cipitated matters might be made 

 to yield some little return in diminution of the cost, and even 

 this appears at present uncertain."

 have been higher floods, it must baw l)een before the advent of 

 the wbiie man. 



Tlie first flood of which I iiav.' any recollection was in
