NOTE.

In view of the increasing importance laid upon a knowledge of the

chemical formation of feed water, these chapters of Chemical Terms and

Analysis of Feed Waters are given to indicate _the direction in which

the advanced engineer must push his inquiries_. There are more millions

of treasure to be made by properly “treating” the water which enters

the steam generators of the world than can be extracted from its gold

mines.

An important “point” is to make sure, before adopting any permanent

system for purifying the waters of a steam plant, that it is always the

same in its ingredients, _i.e._, that the impurities contained in the

water are the same at all times.
