It is not our intention to trace in detail the gradual development of the city since its incorporation in the year 1847, but rather to give the reader some distinct idea of what the City of Hamilton is today as a manufacturing, commercial and educational centre, and as a desirable place for the safe and profitable investment of capital and at the same time a delightful place to live in. Hamilton has always been noted for its mild and even climate, it being several hundred miles south of London, England, and Paris, France, and a little east of the 80th degree of longitude and north of the 43rd parellel of latitude. The cleanness of its streets (its present sewage system being almost perfect, the gradual slope towards the bay making the task very easy), large trunk sew ers being used from the mountain to the bay, and the smaller sewers running from east to west connected with the larger sewers and emptying into the Disposal Works. There are about sixty miles of sewers in the city flow ing into the two Sewage Disposal Works, situated on the bay shore, where it goes through a process of chemical precipitation, alum and lime being used for this purpose, all the solids removed and the affluent turned into the bay as clear as filtered water. The writer believes that these are the only works of the kind in the Dominion now in operation. They have been working for about six years and have contributed a great deal towards keeping the bay free from objectionable matter and its water as pure as that of a mountain spring. The cost entailed in the establishment of these w orks was about $100,000, and the annual cost for maintaining and operating the same approximate $18.000. The waterworks system is ow ned and operated by the municipality, and quite a large revenue is derived from this source. The pumping station and filtering basins are at the peach. about six miles east of the city. There are at present two reservoirs, and another large reservoir is about to be constructed at the head of James street. The water is pumped into the city through three large mains, 20 inch, 24 inch and 30 inch respectively in diameter. The pumping capacity of the plant is about fifteen million gallons per twenty-four hours, and there is laid throughout the city about one hundred and ten miles of water mains. The total cost of installing this plant was about two million dollars.
