THE PLUNKETT'S GAP STREAM.

Unfiltered water, 16 samples.

Amounts of samples tested:-

cc., Acc., lec. for Agar plates.

1cc. on to Lactose Agar coloured plates.

cc., lcc., 2cc., 5cc. Glucose Peptone water.

cc, lcc., 2cc., 5cc., 10cc. Lactose Peptone water.

Organisms isolated are worked out both by the "Coli Group" method and by the full method, (see p. 119.)

This stream and the next (Mount Austin) are really direct feeders of the Reservoir, but as they can and are from time to time diverted so as to run direct into the Conduit without going into the Reservoir at all, they are treated as Intakes. The map* attached shows the areas they drain.
