Discussion on “mill controllers” (Stratton), and “steel mill controllers from the operator´s standpoint” (Riggs), Pittsburgh, Pa., April 15, 1915. (see proceedings for April and May, 1915)

H. F. Stratton: I apologize for appropriating such a big topic as mill controllers, and then discussing only part of one division of it. Nor do I feel that the apology is an empty formality, because I appreciate that other parts of the subject have such a direct bearing on the one discussed that they should be considered at the same time.
