Note 28 — Chapter XXIII

Shanghae, from its situation and over-crowded population, is one of the greatest sufferers from the want of pure water; and there cannot be a doubt that this circumstance has contributed, in no slight degree, to the sickliness that has prevailed there for several years past, as the increase in the population tends more and more to the defilement of the river,—the only source whence water is obtained. The question of water-supply for that settlement having been submitted to practical and experienced engineers in London, the result of their calculations is, that a system of water-works, with reservoirs beyond the influence of sewage, would provide each household with an unlimited supply of pure, filtered water, at about one-fourth of the expense which is at present incurred in merely carrying water from the river to the houses. Messrs. Simpson and Giles have further demonstrated that, at the proposed rate of one shilling per 1,000 gallons, a large return would be secured on the capital necessary to be invested in the works. We may therefore hope that at no distant day the inhabitants of Shanghae, at least, will enjoy this great blessing.
