THE PINE WOOD NULLAH INTAKE.

UNFILTERED WATER,

Method used exactly the same as in the case of the No. 1 Syphon, only all organisms isolated were worked out on the "Coli Group" basis.only.

This area is crossed in two places by the Hatton Road and at the top a Battery with Barracks. These Barracks do not drain into the area, but it is possible that some of the nightsoil may be dumped into the stream. In view of the fact that B. Coli Com- munis was found in 30°, of the samples which is double the percentage of any other intake, the question of nightsoil requires careful investigation.
