work within a reasonable time. In
the top foot of filling material distri-
buting pipes are laid from the gate
chambers, consisting of vitrified sewer
pipes, from II to 3 inches in diameter,
laid with open Joints except the Il
inch pipes, which are cemented.
The partially purified sewage passes
continuously from the septic tank
through Pinch pipe built into the
top of the middle wall to the gate
chamber at the intersection Of the d.
vision walls . here it is diverted by
wooden gates to each of the four
beds in succession. After one bed is
filled for two hours the flow is turned
to the next bed, each of the four re-
ceing the flow in turn. The height OF
water in the beds is indicated by tell
tale balls above the roofs Of gate
chambers.
The sewage in the first bed, after
being retained for two hours, is drawn
off by opening sluice gate Operated
by wheel in the gate hOuse) and passes
through pipe to the gate chamber of
the second set OF contact bees, where
the same process is repeated. After
the period of rest in the second set Of
beds, the efftnent is turned into the
brook
Each bed receives a rest of two hours
before each 6lling, and the material in
the beds is sufficiently coarse TO allow
the air TO be drawn down to the bot
tom of the bed each time.
1t is mot known yet at what rate
slndge will accumulate in the septic
tank, but provision is made for it's re-
moval, when necessary, through an s.
inch pipe connected with each tank
by gate valve and emptying it into
the adjoining sand beds AS the
sludge need be drawn off only at favor
able times, the bed can be suitably
prepared by drying, blowing and ditch
ing.
AT the outlet end of the septic tanks
additional S-inch valves are placed at
the proper height to draw off the clear
est water. 50 that when the sludge is
ito be emptied on one bed, this COM
paratively clear water may be turned
onto another. These valves empty in
to Pinch pipe in the weir wall,
which pipe may discharge onto any Of
the lower sand beds. The water in
the channel may also be turned into
this pipe without passing through the
contact beds, in case it is needed for
irrigation.
An 8-inch valve connects the two
tanks, and another is connected, by an
8-inch pipe, with the lower part of the
| first gate chamber. Through this the
water from the septic tanks may be
turned directly to the lower contact
beds without passing drought the up

Twill be given only so much sewage or
