It is widely known that there is a critical situation in the theories of collective behavior though many contributions, practically and theoretically, have been made untill now. This dead alley of the theories is, in particular, due to the concepts without precision and minutenesses which would make the common understandings among the collective-behaviornists and suggests us to return to Park's studies, that is, contents of arguments of the founder of this sociological domain. This paper aims mainly to examine and reveal the concepts of the crowd and thepublic referring to his studies of collective behavior after 1921.
