In depth was about one-half sewage. At six.
teen hundred feet distance 1T contained about
oneeight hteenth of its bulk of sewage and at |
three thousand two hundred feet, or five
eighths of mile distant from the outlet of the |
sewer, the ammoniss indicated the amount OF /
sewage added to be but one per cent. of the |
volume of water and the same amount an
found in mid stream at the crossing of the |
North Ferry to East Boston. Beyond this dis |
tance the amount of ammonia added became
about one half OF one per cent at mile. and |
less than onetenth of one per cent. at one and
iourifths miles from the outlet.
"Ihese results confirm those of direct obser.
vation. With the. ordinary wave motion at
this place, mile from the outlet. the amount
of sewage remaining near the sur lace of the
water is so smsll that no disagreeable appe ar
ance or odor can be'recognized."
AT Brighton, England, the sewage is dis
charged directly at the shore, five miles from
the bathing beaches. During times when the
littoral currents are towards the city, no trace
F! of sewage can be detected by the eye or By any
odor, one mile from the outlet.
| In the great lakes similar results are OBJ
served. The discharge of the rivers at Mil
waukee. Chicago or Cleveland have, during
| foods, never been followed more than two
miles Into the lake from the point of diseharge.
| The comparatively small amounts OF sewage,
when not mingled with the flood discharges of
| the rivers, have never been noticed more u aa
one mile from the outlet.
From the foregoing it must appear that on &C
count OF the nearness of large areas of irrgable
