Ventilation, Heating and Management of Churches and Public Buildings

the adjoining rooms or wards. Some one ought to be in charge of the ventilation, and alone responsible for it, who should study and master the effects of wind action, and the difficulties attached to the proper control of the inlets, outlets, and other arrangements. Unless this is done, the best planned and furnished system may become inoperative and unworkable, and what might, with proper supervision and a little adjustment, prove perfectly successful, will be condemned as useless and wrong in principle.
