If you think this moisture is bad you ought to see a mill with the old vapour-pot system with the steam shooting out into the room. Look here!" He led Janet to the apparatus in which the pure air is forced through wet cloths, removing the dust, explaining how the ventilation and humidity were regulated automatically, how the temperature of the room was controlled by a thermostat.
To assist the housewife in this matter, as well as to help in the saving of much loss in fuel and in underdone or overdone food, many stoves are equipped with an oven thermometer, an indicator, or a thermostat.
The ordinary incubator thermostat gives the necessary impulse for the control of the temperature dampers, while the instrument above referred to is used for the vapor pressure control. As the entire air circuit is closed, the chemical composition of the air may also be regulated at will.
This, as its name implies, is a forced draft controlled by a thermostat, and with it the cheaper grades of coal can be used. Incidentally, any coal-burning furnace that gets to sulking can be made to respond by placing an ordinary electric fan before the open ash pit. We have done this with a pipeless furnace and have been able to burn the cheaper buckwheat coal almost entirely as a result.

As the freezing of the zinc sulphate solution in cold weather would check its operation, Edison introduced, for example, into the meter an incandescent lamp and a thermostat so arranged that when the temperature fell to a certain point, or rose above another point, it was cut in or out; and in this manner the meter could be kept from freezing.
