I THE LONDON WATER-SUPPLY.* 
(t§\ Y wav of justification for introducing this subject we 
tfg) need merely say that the water-supply of London— a 
matter affefting the well-being, physical, economical, 
and in some sense even moral, of more than one-tenth part 
of the population of the home kingdoms— is no insignificant 
part of P the “ condition of England question. As such it 
may well claim the serious consideration of the public, un- 
less 3 ^ in these days of hysterical sensationalism we have 
utterly abandoned all pretension to be a praftical people. 
We shall do well to remember, further, that eveiy year 
aggravates the evils with which the metropolis is now beset 
and renders their ultimate abolition more and more difficult 
^The water-supply of any community, and certainly of so 
vast a city as London, should, we submit, conform to the 
following conditions In the first place the a ™ llab l e quan- 
tity should be far in excess not merely of the adtual demand, 
but of any total likely to be reached in the future, in accord- 
ance with the increase of the population. Secondly, the 
supply should be not intermittent, but continuous. 1 hirdy^ 
the quality of the water should be unimpeachable. A
