Abstract :
H. S. Phelps: Messrs. Trueblood and Cone have very ably and clearly pointed out the importance of the type of powerdistribution system in the matter of inductive coordination. This importance is recognized, and as the problem is better understood, more and more attention is being given it. It seems to me, however, that they have not placed sufficient stress upon another equally important feature-namely, the characteristics of the telephone system.
