8½ grains to the gallon, and alum, l.8 grains.

cisterns in many of the houses are too small to contain
a sufficient supply I have before remarked upon,

Communications with reference to this
desirable condition have been held with the Company,
but the difficulties in the way, the necessity
of altering the fittings in the houses to satisfy the
requirements of the Company,have prevented it from
being carried out. In my report for 1891 I gave a
detailed statement of the size of the cisterns in
