After all. however, the solution of this problem is largely inthe hands of the user. Iron or steel will corrode, in spite of any-thing that can be done, if certain material is in solution in thewater, particularly dissolved oxygen or carbonic acid. By theremoval of these harmful agencies corrosion may be reduced topractically nothing. It is generally understood nowadays thatwater conditions have everything to do with corrosion, and thesimplest solution of the problem is to treat the water with the ob- Locomotive Tubes and Their Treatment. i85.
