opinion or this committee, as weighed
against the virtues OF an unpolluted at
moSphere In the city.
There are many so-called smoke CON
Surnefs which do not work out success
iuiIy. but we need not devote space in
ms report 20 them. We are concerned
with the question OF preventing smoke
not with the question OF smoke prevent
ers.

are told that the automatic device in
stalled at the Cullen hotel is not guar
aEteed by It's maker to operate success
tully In boilers under 25 pounds pres
that the apparatus will operate at 20
pounds and prevent at least SO per cent
OF the smoke. We recommend that for

the cost. If any.
AS to Residences.
i-For residence nucs which polutc
the air considerably in the winter time
we lind there Is no mechanical device
applicable We consider this an i'm
ton. Our investigation leads us TO be-
lieve that most OF the nuisance from this
source can be prevented by proper fuel.
Ihis committee has not the facilities
Tor making the necessary tests. but we
are told that proper combination OF
coke with coal will prevent smoke in
the residence sections. and we respect
fully recommend TO the general com
mittee that some time between now and
next winter experiments be directed ac-
curately 10 determine this question. This
branch Of the question is not so i'm
Dortant now.
Conclusion-on the whole. your com
mittee finds that many cities. which have
greatly because OF smoke null
sanee. have been able to remedy this
defect We believe that the above re-
port briefly covers the field and shows
the different methods which have been
applied By other cities. There may be
other means of preventing smoke than
those outlined above. II so. Il is all the
more reason why the law should be en-
forced. IL would merely broaden the
field from which smoke makers may
select their remedy.
