In the second paper on ''Iowa Ground Waters '' read before the Iowa Academy of Science at the annual meeting of 1909, the writer, in connection with the subject of the corrosion of well casings called attention to the fact that the city of Grinnell had contracted for a casing of cast iron for well number (4) which was then being drilled. It was suggested that a report would be made on the practicability of this enterprise at a later meeting.
