under close observation from time to time.
Complaint was made early in the year that sewage was, by
some means, finding its way into the river at Beddington, from
the adjoining Corporation Sewage Farm. Examination revealed
that when a certain plot was being irrigated, an increased volume
of water found its way into a neighbouring surface-water drain,
which finally discharged into the river. An analysis of this
water showed that it consisted, largely, of very imperfectly purified
