Mains. 



The water was originally brought from the Chain Lakes to 

 the city by a 12-inch main to St. Andrew's Cross, laid in 1848, 

 and was assumed by Mr. Jarvis to be capable of delivering at 

 this point 800,000 gallons daily. It was of cast iron, and was 

 ordered in Scotland through Messrs. Kidston & Son, of Glas- 

 gow, and cost 7 5s. per ton delivered, the freight being 15/ per 

 ton. 2,550 feet of these pipes were to be f inch thick, to be 

 tested to withstand a pressure of 160 pounds to the square 

 inch, and 13,650 feet to be J inch thick tested to 145 pounds. 

 All pipes were to be 9 feet long. 550 of these pipes were 

 ordered with spigots cast on them to fit a f-inch iron service 

 pipe, so that the water would not have to be turned off in mak- 

 ing connections. The pipes were uncoated and were laid with 

 lead joints. 



In January, 1856, the water company ordered from 

 Kidston & Sons 284 lengths of 15-inch pipe, 9 feet long, f inch 

 thick, to be laid in the valley of the North West Arm, and 1,341 

 lengths f inch thick; the pipes to be tested to 165 and 135 

 pounds respectively. These pipes were laid during that year 

 alongside the 12-inch. The estimated delivery of this pipe was 

 over 1,000,000 gallons per day at St. Andrew's Cross. Messrs. 

 Kidston wrote to the directors recommending the use of a coat- 

 ing (Smith's patent varnish) which was then just coming into 

 use, and the directors wrote saying that if this coating had the 

 approval of authorities in Great Britain to put it On the pipes ; 

 but subsequently, fearing it would reduce the capacity of the 

 pipes, passed the following resolution, a copy of which they 

 sent their agents : 



Resolved, That the directors having ordered a 15-inch 

 pipe, which was larger than was contemplated for the very pur- 

 pose of preventing the pipes filling up, do not consider that the
