 streams just above the Whalley Avenue bridge. South of this bridge 

 the stream runs through Edgewood Park and into widening meadows 

 which at the lower end are tide marshes.

 since 1904, and just east of it for six years prior to that time, he has 

 never seen these mosquitoes in such abundance as during the past three 

 years. It was known that their breeding place was close at hand, for 

 rain-barrel mosquitoes do not breed in the brackish water of the salt 

 marsh. In 1912, when all known mosquito breeding places in and
