STUDIES ON MUSEUMS AND KINDRED INSTITUTIONS. 485. Fig. 63.—Chicago Telephone Company, lating plant. Plan of venti- ventilating" system, I visited the operating room of the Chicago Tele- phone Company in the seventh story of a Iniilding on Washington street, where a similai system has been going on for three years. It was put in because dust was injurious to the electric contact. 1 found there 120 women crowded closely in a relatively small room where daj" and night they do nothing but make and break connec- tions, a slavery ; The ventilation, however, had not been operating for a fortnight, as a wing to the building was under construction and the windows were open, so that the noise of the street was very anno3'ing. I learned that the women who had complained of the ventilation S3'stem since its installation three years before, had during this fortnight when it was not working, wished for its restoration. This reminded me of the experience which I had in the Dresden Museum twenty-five years ago, when the hot w^ater heat- ing plant was installed there. The emploj-ees complained that they were accustomed to heating by stoves and charged their indisposition and illness to the new system of heating. It was only the novelty of the method and their own prejudice that set them against it, as in Chicago, wdiere, however, after experi- ence it became evident that the new arrangement was the l)etter. It will, therefore, be retained by the telephone company. In figs. 61-641 give the plan adopted for the installation of the apparatus, w^hich was given me by the chief engineer of the company, who explained the matter to me with the courtesv which is evervwhere shown in the United.
