At the foot of the entrance staircases (at the Boylston Street and Park Street Stations) are offices at which the admission of five cents must be paid, for which a subway check will be issued, which will be good only on cars taken in the subway and will be void if carried form the subway without using.

Subway checks cannot be purchased in advance for subsequent use.

On arrival at Park Street station, passengers who wish to remain on the cars for the return trip may do so upon payment of another fare.

To avoid accidents, persons carrying long or bulky articles, such as molding, pipes, etc., will not be permitted to enter the subway.

The admission of dogs is prohibited, also the sale of newspapers or other merchandise on cars, within the subway or on the station stairways.
