Analyses were then made with the object of finding the 
point nearest the waterworks, at which a better supply 
could be obtained. Samples were taken on April 30th, 
1891, from the following points : 
No. 1—1300 feet from shore opposite Murney Tower, in line of 
Barrie street (map, D). 
No. 2—At the proposed intake (B). 
No. 3—1200 feet beyond the proposed intake (C). 
No. 4—2500 feet beyond the proposed intake (E). 
No. 5—Near Carruthers’ shoal (F). 
With the exception of No. 5 these samples were taken 30 
ft. from the surface. No. 5 was taken 22 feet from the 
surface. The results of the analyses were as follows : 
Free Albuminoid Oxygen 
No. Ammonia. Ammonia. Chlorine. consumed. Solids. Remarks. 
1.. none 085 4.4 1.72 113 Some sediment. 
2 enone 086 3.9 1.64 118 rf os 
3.. none -062 4.4 0.88 126 Clearer than 1 &2. 
4.. none . 060 4.5 1.12 102 ec “ 
5-. none 060 4.0 1.56 140 Slightly unpleasant 
odour when warm. 
Above D, the point at which No. 1 was taken, the princi- 
pal discharge of sewage is from the Asylum for the Insane, 
and from the Penitentiary. The analysis shows that the 
point D is not superior to the proposed intake (B). It 
also shows that purer water can be obtained by running 
the suction pipe 1,200 feet farther out than was at first 
proposed. JI was much surprised to find that No. 5, with 
albuminoid ammonia so low, had been taken from a point 
so far up in the harbour. In my report it was mentioned 
as inferior to Nos. 3 and 4, as shown by the oxygen consumed, 
the solids, and the unpleasant odour (somewhat marshy, I 
noted it at the time) when distilling. The exceptional 
character may be accounted for on the ground that the 
harbour water is there (at F) mixed with the water of the 
Cataraqui River, a sluggish stream flanked by extensive 
marshes just before it reaches the city. However, the 
point awaits further investigation.
