Matthew, P. Water supply to cities. Gardeners’ Chronicle and Agricultural Gazette (30 Apr 1870), p.598
(Article printed in issue of April 30)
Matthew considers the beneficial effects of particulates such as earth or clay in the water supply.
A slightly edited version of this article also appears in the Dundee Advertiser of 25 April 1870 (letter dated 16 April), and is reproduced in Dempster (1996).
Matthew notes: “The balancings of Nature are admirable, though sometimes not understood by man”
