exhausting the air from some appliance under each car, and
so causing the pressure of the atmosphere to apply the
brakes.

retort used in sugar making for boiling down sirup. It is
so connected with an exhausting apparatus that a partial
vacuum is formed within. This allows the evaporation and

largely obviates the danger of burning the sugar, and
shortens the process.
