CAUSES OF IRREGULAR IDLING.

The description of the American #Robot," which answers 'Its master's voice and obeys his. com- manda, has led British scientists to Indulge in atill more wonderful anticipations.
The musical Intchkey, the "me- chanical detective. the electricul housemaid-all these are threaten- cd. Possibilities were outlined to the Evening Standard by Pro- fessor A. M. Low.
"The American automaton that responds to the human voice is not new in principle," he said.
"One could easily, replace one's latchkey by a device in the lock incorporating a tuning-fork. It would then only be necesary to sing a certain note or group of notes outside and the door would swing

"But it would be awkward if one got home late and forgot the tune!
"Some years ago I made a little gadget which I fixed to the door of my garage." It automatically opened the door as soon as I sound- ed my motor-horn.

"To-day's New York messages say that a housewife may telephone home to her mechanical maid' to inquire about the kitchen oven, and give the automaton orders on being told by it the temperature of the oven.
"It would not be difficult to arrange a temperature indicator on the oven which would cause the automaton to state the heat in figures over the telephone, by means of gramophone records properly arranged inside the Robot.
Careful Modulation.
"The important thing, then, would be to modulate one's own voice carefully, for the electrical ear of the dummy would he set to respond in certain ways to certain tones."
"Although the electrical-acousti cal principles governing such me- chanism have been known for some time, they have not lent themselves so far to any practical use in the home. It is true that Robots are employed to report by telephone the depth of water in American reservoirs, but apart from such isoktted cases the automaton has not yet justified itself for general
Use.
"The multiplication of labour saving devices in this country, how- ever, means that we are getting nearer and nearer the time when everything will be done for mechanically. Perhaps the Robot, then, will come into its own."

FIRE FIGHTING TEST
Trucks Submitted to Gruelling non-Stop Run.
A General Motors truck, poweri ed with the Buick Muster Six motor, recently underwent and successfully withstood the under- writers' standard twelve hour test as the motive for a 600 gallon capacity American-La France fire pump.
This testis naturally the most. severa tryout,imposed in the, au tomotive Industry, for life itself depends to a large extent on the dependability of fire-fighting equipment..
tor.
The motor was tested indoors, placing a tremendous strain on the heating apparatus of the mo For twelve consecutive houra it drove the pumps that delivered 500 gallons of water per minute at a pressure of 120 pounds per square inch, for six hours, 260 gallons per minute at a pressure of 200 pounds per square inch; For three hours and 167 gallons per minute at a pressure of 250 pounds per square inch for the remaining three hours.,
The slightest mishap a carbure. tor adjustment, a new spark plug, or any minor repairs, and the en- xine, would have been disqualified. In the twelve hours, the Buick motor turned over its crankshaft approximately 1,600,000 tinies. This Is equivalent to driving a heavy truck 420 milles in twelve hours, or 35 miles an hour.
No truck in actual service would. ever be required to deliver such, service. In power, the engine. delivered as much as would be required to propel a fully loaded two ton truck up a 6% grade for 206 miles, or 12 miles vertically.
