automatic and immediate—i.e., the moment the slightest
variation takes place in the flow of fresh water into the
box, with (F) float in it, the action of (F) float is instantly
communicated to (S) float, which increases or reduces the
flow of sea water in box with (S) float, to suit the fresh
water production (see also Appendix).

by pumps, the former to drinking water tanks, the latter
to feed the evaporator. In “ multiple ” distillation, as
will be seen presently, this type of feed regulator (auto-
matic in its working) regulates the supply to several
evaporators, each with a different evaporative power, as
well as the feed to a boiler, whose adjusted feed is more
important than that of the evaporators.
