Then, again, take the hotel scheme, for instance. We go to a dial which is marked Room 32. There we find that by treating it in a certain way it will announce to the clerk that Room 32 wants a fire, ice-water, pens, ink, paper, lemons, towels, fire-escape, Milwaukee Sec, pillow-shams, a copy of this book, menu, croton frappe, carriage, laundry, physician, sleeping-car ticket, berth-mark for same, Halford sauce, hot flat-iron for ironing trousers, baggage, blotter, tidy for chair, or any of those things. In fact, I have not given half the list on this barometer because I could not remember them, though I may have added others which are not there. The message arrives at the office, but the clerk is engaged in conversation with a lady. He does not jump when the alarm sounds, but continues the dialogue. Another guest wires the office that he would like a copy of the _Congressional Record_. The message is filed away automatically, and the thrilling conversation goes on. Then No. 7-5/8 asks to have his mail sent up. No. 25 wants to know what time the 'bus leaves the house for the train going East, and whether that train will connect at Alliance, Ohio, with a tide-water train for Cleveland in time to catch the Lake Shore train which will bring him into New York at 7:30, and whether all those trains are reported on time or not, and if not will the office kindly state why? Other guests also manifest morbid curiosity through their transmitters, but the clerk does not get excited, for he knows that all these remarks are filed away in the large black walnut box at the back of the office. When he gets ready, provided he has been through a course of study in this brand of business, he takes one room at a time, and addressing a pale young "Banister Polisher" by the name of "Front," he begins to scatter to their destinations, baggage, towels, morning papers, time-tables, etc., all over the house.
