Two samples were collected on the sands near Fair- 
haven Lake: (a) near the Lake itself, and (6) further 
away and on the seaward side of a gutter, on to the shore 
side of which emptied a sewer. A water sample was taken 
from the gutter, over against the sewer outfall; but on 
the opposite side, and to windward. There was a strong 
S.E. breeze, and there had been much snow and rain, so 
that the water in this gutter was probably less polluted 
than it would have been in fine weather.
