Missouri filed its bill in this Court to enjoin Illinois and the
Sanitary District of Chicago from discharging sewage through an
artificial channel connecting Lake Michigan with the Desplaines
River, a tributary of the Illinois, the latter of which empties
into the Mississippi River above St. Louis, claiming that such
sewage so polluted the water of the Mississippi as to render it
unfit to drink and productive of typhoid fever and other diseases.
Illinois denied the jurisdiction of this Court, and the allegations
of the bill, and alleged that, if the conditions complained of at
St. Louis existed, they resulted from discharge of sewage into the
Mississippi by cities of Missouri and from other causes for which
Illinois was not responsible. A demurrer was overruled, with leave
to answer,
180 U. S. 180 U.S.
208; after answer and taking of proof, including much expert
testimony as to effect of sewage on water and health,
held
that:
This Court has jurisdiction and authority to deal with a
question of this nature between two states which, if it arose
between two independent sovereignties, might lead to war.
In such a case, while this Court cannot take the place of a
legislature, it must determine whether there is any principle of
law, and if any, what, on which the plaintiff state can
recover.
Every matter which would be cognizable in equity if between
private citizens in the same jurisdiction would not warrant this
Court in interfering if such matter arose between states; this
Court should only intervene to enjoin the action of one state at
the instance of another when the case is of serious magnitude,
clearly and fully proved, and in such a case, only such principles
should be applied as this Court is prepared deliberately to
maintain.
While a state may have relief in this Court against another
state to prevent it from discharging sewage through an artificial
channel into, and thereby polluting the waters of, a river flowing
through both states and on which the complainant state relies for
water supply, if the alleged facts as to such pollution are not
fully proved, and it also appears that such pollution might result
from the discharge of sewage by cities of the complainant state
into the same river the bill should be dismissed, but in this case
without prejudice.
The reasons on which prescription for a public nuisance is
denied or granted to individuals against the sovereign power to
which he is subject have no application to an independent state,
but it would be contradicting a fundamental principle of human
nature not to allow effect to the lapse of time. The fixing of a
definite time, however, is usually for the legislature, and not for
the courts.

The mere fact that the drainage canal, constructed by authority
of Illinois and also under authority of an act of Congress, brought
water from the Lake Michigan watershed into the watershed of the
Mississippi does not, in the absence of proof of the deleterious
effects of such water, render the canal an unlawful structure the
use whereof should be enjoined at the instance of another state in
the Mississippi watershed.
The facts, which involved the right of the defendants to
discharge the sewage of Chicago through an artificial channel into
the Desplaines River, which empties into a tributary of the
Mississippi River, are stated in the opinion of the Court.
Page 200 U. S. 517
MR. JUSTICE HOLMES delivered the opinion of the Court.
This is a suit brought by the State of Missouri to restrain the
discharge of the sewage of Chicago through an artificial channel
into the Desplaines River, in the State of Illinois. That river
empties into the Illinois River, and the latter empties into the
Mississippi at a point about forty-three miles above the City of
St. Louis. It was alleged in the bill that the result of the
threatened discharge would be to send 1,500 tons of poisonous filth
daily into the Mississippi, to deposit great quantities of the same
upon the part of the bed of the last-named river belonging to the
plaintiff, and so to poison the water of that river, upon which
various of the plaintiff's cities, towns, and inhabitants depended,
as to make it unfit for drinking, agricultural, or manufacturing
purposes. It was alleged that the defendant sanitary district was
acting in pursuance of a statute of the State of Illinois, and as
an agency of that state. The case is stated at length in
180 U. S. 180 U.S.
208, where a demurrer to the bill was overruled. A supplemental
bill alleges that, since the filing of the original bill, the
drainage canal has been opened and put into operation, and has
produced and is producing all the evils which were apprehended when
the injunction first was asked. The answers deny the plaintiff's
case, allege that the new plan sends the water of the Illinois
River into the Mississippi much purer than it was before, that many
towns and cities of the plaintiff along the Missouri and
Mississippi discharge their sewage into those rivers, and that, if
there is any trouble, the plaintiff must look nearer home for the
cause.
The decision upon the demurrer discussed mainly the jurisdiction
of the court, and, as leave to answer was given when the demurrer
was overruled, naturally there was no very precise consideration of
the principles of law to be applied if the plaintiff should prove
its case. That was left to the future,
Page 200 U. S. 518
with the general intimation that the nuisance must be made out
upon determinate and satisfactory evidence, that it must not be
doubtful, and that the danger must be shown to be real and
immediate. The nuisance set forth in the bill was one which would
be of international importance -- a visible change of a great river
from a pure stream into a polluted and poisoned ditch. The only
question presented was whether, as between the states of of the
Union, this Court was competent to deal with a situation which, if
it arose between independent sovereignties, might lead to war.
Whatever differences of opinion there might be upon matters of
detail, the jurisdiction and authority of this Court to deal with
such a case as that is not open to doubt. But the evidence now is
in, the actual facts have required for their establishment the most
ingenious experiments, and for their interpretation the most subtle
speculations, of modern science, and therefore it becomes necessary
at the present stage to consider somewhat more nicely than
heretofore how the evidence in it is to be approached.
The first question to be answered was put in the well known case
of the Wheeling bridge.
Pennsylvania v. Wheeling &
Belmont Bridge Co., 13 How. 518. In that case also,
there was a bill brought by a state to restrain a public nuisance
-- the erection of a bridge alleged to obstruct navigation -- and a
supplemental bill to abate it after it was erected. The question
was put most explicitly by the dissenting judges, but it was
accepted by all as fundamental. The Chief Justice observed that, if
the bridge was a nuisance, it was an offense against the
sovereignty whose laws had been violated, and he asked what
sovereignty that was. 13 How.
54 U. S. 561;
Daniel, J., 13 How.
54 U. S. 599.
See also Kansas v. Colorado, 185 U.
S. 125. It could not be Virginia, because that state had
purported to authorize it by statute. The Chief Justice found no
prohibition by the United States. 13 How. 508. No third source of
law was suggested by anyone. The majority accepted the Chief
Justice's postulate, and found an answer in what Congress had
done.
It hardly was disputed that Congress could deal with the
Page 200 U. S. 519
matter under its power to regulate commerce. The majority
observed that, although Congress had not declared in terms that a
state should not obstruct the navigation of the Ohio by bridges,
yet it had regulated navigation upon that river in various ways,
and had sanctioned the compact between Virginia and Kentucky when
Kentucky was let into the Union. By that compact, the use and
navigation of the Ohio, so far as the territory of either state lay
thereon, was to be free and common to the citizens of the United
States. The compact, by the sanction of Congress, had become a law
of the Union. A state law which violated it was unconstitutional.
Obstructing the navigation of the river was said to violate it, and
it was added that more was not necessary to give a civil remedy for
an injury done by the obstruction. 13 How.
54 U. S.
565-566. At a later stage of the case, after Congress
had authorized the bridge, it was stated again in so many words
that the ground of the former decision was that "the act of the
Legislature of Virginia afforded no authority or justification. It
was in conflict with the acts of Congress, which were the paramount
law."
59 U. S. 18 How.
421,
59 U. S.
430.
In the case at bar, whether Congress could act or not, there is
no suggestion that it has forbidden the action of Illinois. The
only ground on which that state's conduct can be called in question
is one which must be implied from the words of the Constitution.
The Constitution extends the judicial power of the United States to
controversies between two or more states, and between a state and
citizens of another state, and gives this Court original
jurisdiction in cases in which a state shall be a party. Therefore,
if one state raises a controversy with another, this Court must
determine whether there is any principle of law, and, if any, what,
on which the plaintiff can recover. But the fact that this Court
must decide does not mean, of course, that it takes the place of a
legislature. Some principles it must have power to declare. For
instance, when a dispute arises about boundaries, this Court must
determine the line, and, in doing so, must be governed by rules
explicitly
Page 200 U. S. 520
or implicitly recognized.
Rhode Island v.
Massachusetts, 12 Pet. 657,
37 U. S. 737.
It must follow and apply those rules even if legislation of one or
both of the states seems to stand in the way. But the words of the
Constitution would be a narrow ground upon which to construct and
apply to the relations between states the same system of municipal
law in all its details which would be applied between individuals.
If we suppose a case which did not fall within the power of
Congress to regulate, the result of a declaration of rights by this
Court would be the establishment of a rule which would be
irrevocable by any power except that of this Court to reverse its
own decision, an amendment of the Constitution, or possibly an
agreement between the states, sanctioned by the legislature of the
United States.
The difficulties in the way of establishing such a system of law
might not be insuperable, but they would be great and new. Take the
question of prescription in a case like the present. The reasons on
which prescription for a public nuisance is denied or may be
granted to an individual as against the sovereign power to which he
is subject have no application to an independent state.
See 1 Oppenheim, International Law 293, §§ 242,
243. It would be contradicting a fundamental principle of human
nature to allow no effect to the lapse of time, however long,
Davis v. Mills, 194 U. S. 451,
194 U. S. 457,
yet the fixing of a definite time usually belongs to the
legislature, rather than the courts. The courts did fix a time in
the rule against perpetuities, but the usual course, as in the
instances of statutes of limitation, the duration of patents, the
age of majority, etc., is to depend upon the lawmaking power.
It is decided that a case such as is made by the bill may be a
ground for relief. The purpose of the foregoing observations is not
to lay a foundation for departing from that decision, but simply to
illustrate the great and serious caution with which it is necessary
to approach the question whether a case is proved. It may be
imagined that a nuisance might be created by a state upon a
navigable river like the Danube, which would
Page 200 U. S. 521
amount to a
casus belli for a state lower down unless
removed. If such a nuisance were created by a state upon the
Mississippi, the controversy would be resolved by the more peaceful
means of a suit in this Court. But it does not follow that every
matter which would warrant a resort to equity by one citizen
against another in the same jurisdiction equally would warrant an
interference by this Court with the action of a state. It hardly
can be that we should be justified in declaring statutes ordaining
such action void in every instance where the circuit court might
intervene in a private suit upon no other ground than analogy to
some selected system of municipal law and the fact that we have
jurisdiction over controversies between states.
The nearest analogy would be found in those cases in which an
easement has been declared in favor of land in one state over land
in another. But there the right is recognized on the assumption of
a concurrence between the two states, the one, so to speak,
offering the right, the other permitting it to be accepted.
Mannville Co. v. Worcester, 138 Mass. 89. But when the
state itself is concerned, and by its legislation expressly
repudiates the right set up, an entirely different question is
presented.
Before this Court ought to intervene, the case should be of
serious magnitude, clearly and fully proved, and the principle to
be applied should be one which the court is prepared deliberately
to maintain against all considerations on the other side.
See
Kansas v. Colorado, 185 U. S. 125.
As to the principle to be laid down, the caution necessary is
manifest. It is a question of the first magnitude whether the
destiny of the great rivers is to be the sewers of the cities along
their banks or to be protected against everything which threatens
their purity. To decide the whole matter at one blow by an
irrevocable fiat would be at least premature. If we are to judge by
what the plaintiff itself permits, the discharge of sewage into the
Mississippi by cities and towns is to be expected. We believe that
the practice of discharging into the river is
Page 200 U. S. 522
general along its banks, except where the levees of Louisiana
have led to a different course. The argument for the plaintiff
asserts it to be proper within certain limits. These are facts to
be considered. Even in cases between individuals, some
consideration is given to the practical course of events. In the
black country of England, parties would not be expected to stand
upon extreme rights.
St. Helen's Smelting Co. v. Tipping,
11 H.L.C. 642.
See Boston Ferrule Co. v. Hills, 159 Mass.
147, 150. Where, as here, the plaintiff has sovereign powers and
deliberately permits discharges similar to those of which it
complains, it not only offers a standard to which the defendant has
the right to appeal, but, as some of those discharges are above the
intake of St. Louis, it warrants the defendant in demanding the
strictest proof that the plaintiff's own conduct does not produce
the result, or at least so conduce to it, that courts should not be
curious to apportion the blame.
We have studied the plaintiff's statement of the facts in
detail, and have perused the evidence, but it is unnecessary for
the purposes of decision to do more than give the general result in
a very simple way. At the outset, we cannot but be struck by the
consideration that, if this suit had been brought fifty years ago,
it almost necessarily would have failed. There is no pretense that
there is a nuisance of the simple kind that was known to the older
common law. There is nothing which can be detected by the
unassisted senses -- no visible increase of filth, no new smell. On
the contrary, it is proved that the great volume of pure water from
Lake Michigan which is mixed with the sewage at the start has
improved the Illinois River in these respects to a noticeable
extent. Formerly it was sluggish and ill smelling. Now it is a
comparatively clear stream to which edible fish have returned. Its
water is drunk by the fishermen, it is said without evil results.
The plaintiff's case depends upon an inference of the unseen. It
draws the inference from two propositions. First, that typhoid
fever has increased considerably since the change and that other
explanations
Page 200 U. S. 523
have been disproved, and second that the bacillus of typhoid can
and does survive the journey and reach the intake of St. Louis in
the Mississippi.
We assume the now-prevailing scientific explanation of typhoid
fever to be correct. But when we go beyond that assumption,
everything is involved in doubt. The data upon which an increase in
the deaths from typhoid fever in St. Louis is alleged are disputed.
The elimination of other causes is denied. The experts differ as to
the time and distance within which a stream would purify itself. No
case of an epidemic caused by infection at so remote a source is
brought forward, and the cases which are produced are controverted.
The plaintiff obviously must be cautious upon this point, for if
this suit should succeed, many others would follow, and it not
improbably would find itself a defendant to a bill by one or more
of the states lower down upon the Mississippi. The distance which
the sewage has to travel (357 miles) is not open to debate, but the
time of transit, to be inferred from experiments with floats, is
estimated as varying from eight to eighteen and a half days, with
forty-eight hours more from intake to distribution, and when
corrected by observations of bacteria, is greatly prolonged by the
defendants. The experiments of the defendant's experts lead them to
the opinion that a typhoid bacillus could not survive the journey,
while those on the other side maintain that it might live and keep
its power for twenty-five days or more, and arrive at St. Louis.
Upon the question at issue, whether the new discharge from Chicago
hurts St. Louis, there is a categorical contradiction between the
experts on the two sides.
The Chicago drainage canal was opened on January 17, 1900. The
deaths from typhoid fever in St. Louis, before and after that date,
are stated somewhat differently in different places. We give them
mainly from the plaintiff's brief: 1890, 140; 1891, 165; 1892, 441;
1893, 215; 1894, 171; 1895, 106; 1896, 106; 1897, 125; 1898, 95;
1899, 131; 1900, 154; 1901, 181; 1902, 216; 1903, 281. It is argued
for the defendant that the numbers
Page 200 U. S. 524
for the later years have been enlarged by carrying over cases
which in earlier years would have been put into a miscellaneous
column (intermittent, remittent, typho-malaria, etc., etc.), but we
assume that the increase is real. Nevertheless, comparing the last
four years with the earlier ones, it is obvious that the ground for
a specific inference is very narrow if we stopped at this point.
The plaintiff argues that the increase must be due to Chicago,
since there is nothing corresponding to it in the watersheds of the
Missouri or Mississippi. On the other hand, the defendant points
out that there has been no such enhanced rate of typhoid on the
banks of the Illinois as would have been found if the opening of
the drainage canal were the true cause.
Both sides agree that the detection of the typhoid bacillus in
the water is not to be expected. But the plaintiff relies upon
proof that such bacilli are discharged into the Chicago sewage in
considerable quantities; that the number of bacilli in the water of
the Illinois is much increased, including the
bacillus coli
communis, which is admitted to be an index of contamination,
and that the chemical analyses lead to the same inference. To prove
that the typhoid bacillus could make the journey, an experiment was
tried with the
bacillus prodigiosus, which seems to have
been unknown, or nearly unknown, in these waters. After preliminary
trials, in which these bacilli emptied into the Mississippi near
the mouth of the Illinois were found near the St. Louis intake and
in St. Louis in times varying from three days to a month, one
hundred and seven barrels of the same, said to contain one thousand
million bacilli to the cubic centimeter, were put into the drainage
canal near the starting point on November 6, and on December 4 an
example was found at the St. Louis intake tower. Four others were
found on the three following days, two at the tower and two at the
mouth of the Illinois. As this bacillus is asserted to have about
the same length of life in sunlight in living waters as the
bacillus typhosus, although it is a little more hardy, the
experiment is thought to prove one element of the plaintiff's case,
although
Page 200 U. S. 525
the very small number found in many samples of water is thought
by the other side to indicate that practically no typhoid germs
would get through. It seems to be conceded that the purification of
the Illinois by the large dilution from Lake Michigan (nine parts
or more in ten) would increase the danger, as it now generally is
believed that the bacteria of decay, the saprophytes, which
flourish in stagnant pools, destroy the pathogenic germs. Of
course, the addition of so much water to the Illinois also
increases its speed.
On the other hand, the defendant's evidence shows a reduction in
the chemical and bacterial accompaniments of pollution in a given
quantity of water, which would be natural in view of the mixture of
nine parts to one from Lake Michigan. It affirms that the Illinois
is better or no worse at its mouth than it was before, and makes it
at least uncertain how much of the present pollution is due to
Chicago and how much to sources further down, not complained of in
the bill. It contends that, if any bacilli should get through, they
would be scattered and enfeebled and would do no harm. The
defendant also sets against the experiment with the
bacillus
prodigiosus a no less striking experiment with typhoid germs
suspended in the Illinois River in permeable sacs. According to
this, the duration of the life of these germs has been much
exaggerated, and in that water would not be more than three or four
days. It is suggested by way of criticism that the germs may not
have been of normal strength, that the conditions were less
favorable than if they had floated down in a comparatively
unchanging body of water, and that the germs may have escaped; but
the experiment raises at least a serious doubt. Further, it hardly
is denied that there is no parallelism in detail between the
increase and decrease of typhoid fever in Chicago and St. Louis.
The defendant's experts maintain that the water of the Missouri is
worse than that of the Illinois, while it contributes a much larger
portion to the intake. The evidence is very strong that it is
necessary for St. Louis to take preventive measures, by filtration
or otherwise, against the dangers of the
Page 200 U. S. 526
plaintiff's own creation or from other sources than Illinois.
What will protect against one will protect against another. The
presence of causes of infection from the plaintiff's action makes
the case weaker in principle as well as harder to prove than one in
which all came from a single source.
Some stress was laid on the proposition that Chicago is not on
the natural watershed of the Mississippi, because of a rise of a
few feet between the Desplaines and the Chicago Rivers. We perceive
no reason for distinction on this ground. The natural features
relied upon are of the smallest. And if, under any circumstances,
they could affect the case, it is enough to say that Illinois
brought Chicago into the Mississippi watershed in pursuance not
only of its own statutes, but also of the Acts of Congress of March
30, 1822, c. 14, 3 Stat. 659, and March 2, 1827, c. 51, 4 Stat.
234, the validity of which is not disputed.
Wisconsin v.
Duluth, 96 U. S. 379. Of
course, these acts do not grant the right to discharge sewage, but
the case stands no differently in point of law from a suit because
of the discharge from Peoria into the Illinois, or from any other
or all the other cities on the banks of that stream.
We might go more into detail, but we believe that we have said
enough to explain our point of view and our opinion of the evidence
as it stands. What the future may develop, of course, we cannot
tell. But our conclusion upon the present evidence is that the case
proved falls so far below the allegations of the bill that it is
not brought within the principles heretofore established in the
cause.
Bill dismissed without prejudice.
