THE EVAPORATOR.

the amount of water that runs through the hole. As
this feed-water runs into the evaporator the quantity is
fixed by the maximum amount of sea water evaporated.
This is, of course, if the evaporator is working at atmo-
spheric pressure. If it is working at a pressure, then the
feed-water, instead of being allowed to run into the
evaporator, must be pumped in.

97. This type of feed regulator fixes the uniform
.amount of feed-water; but it does not vary its quantity,
so as to be always in proportion to the amount of evap-
oration that is taking place inside the evaporator, unless
the inlet cock to the feed-box is manipulated by hand so
as to keep the water at a lower level. Fig. 11 shows a
feed-box described in § 96. The feed-water enters the
feed-box at (A), and its passage into the box at (B) is
