$One hundred gallons of water of 34° hardness will require 74 oz. of soap to wash with. One hundred gallons of water of 6°'7 hardness will require 15 oz., as under :— 'Oz. of Hardness. fcurd 8°aP to form a lather. 100 gallons of . 34-0 ... 74 ■'• 100 „ ... 6-7 ... 15 Excess of hardness 27 ■ 3 59 'waste of soap ; or a waste of 3 lbs. 11 oz. of soap to each 100 gallons of the harder water, now supplied by this pant, which at 5d. a lb. will be rather more than I*. &\d* The use. of this softer water for washing alone will more than save the whole water-rent proposed to be charged, and such would be the result from the use of soft water throughout the union. At the same time that the works for the water-supply of Alnwick are carried out, the deep drainage of the moor may be forwarded. And if this work could be accomplished under the powers of the local Board (with the consent, of the parties interested in it) for the benefit of the town, the source of the water-supply would be improved, the land, at present in a great measure waste, be turned into value, and the whole community be benefited.
