tribution, but would seek powers by which this water should be 

 accessible in every direction, in which entcrprize may seize upon 

 a good locality, in which to plant real estate. 



In the district of Hochelaga. the future Leith of our city, we 

 have, as shown in an earlier portion of this paper, cut off the 

 inhabitants from a reasonable enjoyment of our common river, 

 by impregnating the same with sewage at the new outlet of Col- 

 borne avenue. 



We also stand in great danger of permanently contaminating 

 the water of Longueuil, and therefore the extension of the city 

 southward ; and the projection of the sewage at a more northern 

 point much beyond the present will be an absolute necessity in 

 the near future. For the provision of an ample supply of good 

 water the municipality of Hochelaga have made diligent search, 

 but no available source has been discovered nearer than the Back 

 river. Hochelaga must therefore depend on Montreal for a 

 water supply. 



The district of St. Cunegonde at the west also requires water, 

 and a large water supply. The farm of Prof. Macgregor at Brae- 

 side furnishes a remarkable spring, which would afford a whole- 

 some and large supply of water from the Laurentian hills on the 

 north. 



My analysis of this spring, made in April last, gave the follow- 

 ing result : 



Total solid contents per imperial gallon - 31.30 

 Hardness by Clark, 19^ 



Albumenoid nitrogen - . . no trace. 



Carbonate of lime and magnesia - 22.00 



Organic carbon .... I.75 



Silicious carbon . . . . 2.30 



Silica wh. iron and alumina - - .10 



Chlorine (combined) ... 1,72 



Sulphuric acid do. ... .73 



Alkaline bases . _ . _ 2.70 



31.30 

 This is a very excellent water, but rather hard for domestic 



and industrial purposes. I am informed that the flow of the 



spring is equal to about 4000 gals, per diem. 



At Cote St. Antoine, outside the city limits, the residents are 



supplied by water carts, which are sometimes replenished from
