INITIATION
OF STREET CARS

The season is here when street car patrons
are interested in the ventilation of the cars.
Some are interested in the ventilation only as
it affects the temperature, while others con-
slider the temperature matter Of secondary
Importance, as compared to the purity of the
air. With the thought that it may add to the
comfort of the latter, we wish, at the outset, to
inform them that there are two sources of
bringing fresh air into our cars that are not
generally known and that can never be closed
by the passenger who objects to drafts. One
consists Of twenty-six oval openings in the steel
side frame of the car about one inch from the
floor. These openings communicate directly
with the outside through twenty-six holes in the
car stills, one directly under each window pocket:
The air which comes through these openings
passes over the heating pipes and being
warmed by them is not recognized as "fresh
air." although it comes directly from the out
side.
The other means of ventilation is the suction pipe
of the air compressor which opens into the body of
the car under of the seats. The pump, which
furnishes compressed air for operating the brakes
and whistle, is working much of the time, although
it is not usually heard except when the is at
standstill It pumps all the air it uses from the in
terror Of the car, forcing equivalent volume Of
fresh air to enter the car from outside.
These two hidden means Of ventilation arc not
sufficient to supply fresh air to all the passengers in
crowded car with doors, windows and ventiators
closed but they help materially and will keep the air
pure without other openings when there are only
few passengers aboard.

all of our patrons all of the time, and the air in

various kinds of perfumes used by the passengers
The company endeavors to come as near as pos
sble to pleasing all of its patrons in the matter of
ventlating and in heating its cars well as in other
features of its service and instructions to its employees
given with that end in view. Patrons who have
extreme notions about either the temperature the
purity of the air must necessarily yield somewhat
the notions of their fellow passengers. Conductors
are instructed and passengers requested not to
open deck ventlators Immediately behind the smoke
pipe from the heater, when these open gas
