feet 'long, and that: the surface of Long -Lake be raised from its 

 elevation of 175 feet to 200 foet above tide bv a dam at its 

 cutlet at Mclntosh's run. Mr. Jarvis estimated the population 

 of the town at from 20,000 to 25,000, and that there would be 

 1500 water takers within five years . from the introduction of 

 the supply, and that this number would ultimately reach 2000. 

 This would require, at 200 gals, for each tenant, 400,000 

 gals per day. The natural flow from the vallev of the Chain 

 Lakes was' estimated to be capable of supplying the mill owners 

 who had rights in the stream and dams alreadv built, and to 

 furnish the town with 300,000 gals per day for five months 

 in the year, leaving seven months supply to be stored in the 

 reservoirs. This supply he estimated could be obtained from 

 'the Chain Lakes storage reservoir. In his report he makes no 

 mention of any data regarding precipitation, and the presump- 

 tion is that as there were- no records for Xova Scotia in exist- 

 ence previous to this record, the Kew York or Massachusetts 

 records were taken. He recommended that a 12-inch pipe, 

 which wab estimated to be capable of discharging 800,000 

 gallons per day Avhen new, but only 700,000 when incrusted, 

 be laid from the Chain Lakes to the reservoir in the city. The 

 estimated cost of the works, including Long Lake, the reservoir 

 on Wind Mill Hill and the distribution, was about $120,000. 

 The reservoir was proposed to be 1.58 acres in area and about 

 15 feet deep, which would hold a supply when drawn down of 

 about 5,000,000, gallons. 



Before leaving this report, there is a clause dealing with 

 the principle of municipal ownership of water-works which 

 should be quoted, especially as the question of municipalities 

 owning or controlling all public utilities is to-day a very live 

 issue. After reciting several benefits following the introduc- 

 tion of water-works, he says : "A good supply of pure water 

 has a further public benefit in promoting the cleanliness, 

 health and general comfort of the citizens. These, are con-
