Mr. Good presents information in his article which will be useful to those corrosion engineers who must deal with the complex problems encountered in the selection of proper locations for anodes and of the design of proper types of anode systems. The reader may gain the impression from the beginning of this paper that here is another set of calculations based upon assumed conditions that one seldom, if ever, actually encounters. The uniform soil resistivity, for instance, which is assumed for the calculation of resistance of anode systems having various configurations, various lengths, and various depths of burial would rarely occur in actual soils, and once found could not be expected to prevail throughout the various seasons of the year.
The information given in Table I shows, however, that the calculated and the actual total circuit resistance agree remarkably well. The differences between actual and calculated values of from 0.0...
