CITY SANITATION AND SEWAGE DISPOSAL. 



Bv L. J. Clark. 



It gives me great pleasure to have the opijortunity of again 

 htringing before your attention a suVyect fiaught with so much 

 interest to the people of Toronto, as the safe and economic disjio.sal of 

 its sewage. This is a subject that is engaging the attention and 

 taxing to the utmost the ingenuity of all urban municipalities 

 where the health of the community is held in any regard. 



It is also with a good deal of diffidence that I take up a subject 

 ■we might naturally look for the solution of, at the hands of medical 

 men and civil engineers. Perhaps you will say that it Ls on the 

 theoiy that " fools rush in where angels fear to tread," but I would 

 ask you to reserve judgment till you hear what I have to say on the 

 subject, and then render your verdict according to the facts sub- 

 mitted. 



City sanitation in its broader sense applies to water supply, house 

 construction, plumbing, street cleaning, meat and milk inspection, 

 etc., as well as sewage disjjosal, but as those departments are in com- 

 petent bands, I shall on the present occasion confine myself to the 

 latter subject. 



Before entering into the particular scheme I advocate I shall 

 briefly refer to .some of the schemes already in the field. 



They may be designated : 1st, as Messrs. McAlpine and TuUy's ; 

 2nd, Mr. C. Sproat's ; 3rd, Messrs. Herring and Gray's ; 4th, 

 Porous CarVjon System ; and 5th, The Iron deodorizing process. 

 Tlie two latter methods may do veiy well in small towns and inland 

 cities where there is only a choice between these ways and land fil- 

 tration or sewage farms. But where there is such a che^p and 

 effectual way of getting rid of the trouble, as obtains in Toronto, they 

 are quite uncalled for.
