A number of other tests was made, but the above is sufficient to 

 show that bacteria do not find their proper environment and neces- 

 sary pabulum out in the free waters of Lake Ontai'io. 



The analyses that have been made by Dr. Ellis are quite as satisfac- 

 tory as those of Prof. Wright. I would strongly recommend that 

 these analyses be made pei-iodically and published in the city papers. 

 It would also be well to make a special analysis at the pi-esent time 

 of the sewage at the foot of Yonge Street to prove the effectiveness of 

 the Conder system. 



I now come to my last consideration and that is, what will it cost 

 to bring about this desirable state of affairs 1 And here I may say 

 that no city that I have seen or know anything about can be drained 

 so cheaply as Toronto. 



While Brock ville, Kingston and Ottawa, or Rochester on the other 

 side of the line; have to drift their way through rock and contend 

 with ravines we have nothing of the kind in the city proper, and the 

 slope to the south and east is all that could be desired. 



Our largest expenditure would be for the outlet pipe. I have based 

 the cost of this on the price paid to Mr. J. Abell by the city for the 

 water works extension, 12,500 feet of steel pipe, 6 feet in diameter, 

 at $12 per foot would cost $150,000. For laying the same I have 

 made an estimate of $80,000, and as Mr. McNamee, of Montreal, 

 gets $40,00 for laying the water works pipe nearly the same dis- 

 tance, viz., 10,600 feet, with a lot of rock excavation to make, I nius^ 

 surely be on the safe side. For Front Street sewer Messrs. Herring 

 and Gray estimated 857,212 from Garrison Creek to Parliament 

 Street, I allow $120,0 as I require a larger sewer. For making 

 connections with the ]n-esent sewers, $20,000. These are Messrs. 

 Herring and Gray's figures for all the connections from Gan-ison 

 Creek to Pape Avenue : — 4,000 feet on Gerrard Street, at $10 per
