What had occurred by July 9th? Why?

Bathers returned and ventured back into the water, seeming to forget about the recent attacks. Asbury Park advertised that their waters were safe from sharks. The US Bureau of Fisheries declared that people should not be deterred from going into the waters since "sharks were not vicious" (p. 82). Sharks were deemed to be less a threat to man than horses and dogs. This occurred for several reasons. First, many resorts wanted to keep from losing guests, and many truly believed that humans were in no danger from sharks.
