Tuesday, July 13, seats will be erected on the near Aspen Grove cemetery, o looking the track, and every facility will be afforded the public to witness the No. 4 stop, which is the most interesting of all. A large bulletin will be erected at this point, and an operator will bulletin the starts and stops so that they may remain on the board the entire day. A portion of the seats will be roped off for the committee’s guests, but tbe remainder will be open to all. It is hoped by this arrangement to afford the public such facilities for viewing the tests that they will remain away from thetiacks.
