Discussion on “does it pay the average coal mine to purchase central station power?” (Bright), Pittsburgh, Pa., April 27, 1912. (see proceedings for May, 1912)

E. D. Dreyfus: We are indebted to Mr. Bright for having added another interesting chapter on the subject of electric drive and the use of central station power and in taking the opportunity of opening the discussion I wish to make note of some important facts which should be kept in mind in connection with the quotation of rates for power purposes. Mr. Bright has been obliged to confine his comparisons to specific cases only and personally I feel that his deductions are very instructive and valuable.
