1. As the effect of the statute of Iowa is to make an occupant
of land in that state, who, under color of title thereto, and in
good faith, has made valuable improvements thereon, the owner of
the improvements, the question as to the ownership of the land is
immaterial in an action to recover for their willful or negligent
destruction.
2. Where the subject of a proposed inquiry before a court is not
a matter of science, but of common observation, upon which the
ordinary mind is capable of forming a judgment, experts ought not
to be permitted to state their conclusions.
3. The question as to what is the proximate cause of an injury
is ordinarily not one of science or of legal knowledge, but of fact
for the jury to determine in view of the accompanying
circumstances.
4. A finding that negligence, or an act not amounting to wanton
wrong, is the proximate cause of an injury is not warranted, unless
it appear that the
Page 94 U. S. 470
injury was the natural and probable consequence of the
negligence or wrongful act and that it ought to have been foreseen
in the light of the attending circumstances. Where there is no
intermediate efficient cause, the original wrong must be considered
as reaching to the effect and proximate to it.
5. The finding of the jury in this case that the burning of the
plaintiff's mill and lumber was the unavoidable consequence of the
burning of the defendants' elevator, which had been caused by their
negligence, is in effect a finding that there was no intervening
and independent cause between the negligent conduct of the
defendants and the injury to the plaintiff.
The facts are stated in the opinion of the Court.
MR. JUSTICE STRONG delivered the opinion of the Court.
This was an action to recover compensation for the destruction
by fire of the plaintiff's sawmill and a quantity of lumber,
situated and lying in the State of Iowa and on the banks of the
river Mississippi. That the property was destroyed by fire was
uncontroverted. From the bill of exceptions, it appears that
the
"plaintiff alleged the fire was negligently communicated from
the defendants' steamboat
Jennie Brown to an elevator
built of pine lumber, and one hundred and twenty feet high, owned
by the defendants, and standing on the bank of the river, and from
the elevator to the plaintiff's sawmill and lumber piles, while an
unusually strong wind was blowing from the elevator towards the
mill and lumber. On the trial, it was admitted that the defendants
owned the steamboat and elevator; that the mill was five hundred
and thirty-eight feet from the elevator, and that the nearest of
plaintiff's piles of lumber was three hundred and eighty-eight feet
distant from it. It was also admitted that there was conflict
between the parties plaintiff and defendant respecting the
ownership of the land where the mill stood and the lumber was
piled, both claiming under a common source of title. The plaintiff
had built the mill, and he was in the occupation of it, believing
he had a right to be there."
Such having been the admissions, the court refused to allow
Page 94 U. S. 471
the parties to try the title to the land upon which the mill and
lumber had been placed, proof of title being, in the opinion of the
court, immaterial. To this ruling the defendants excepted, and it
is the first error they have assigned. We are unable to perceive
any reason why the proof offered was not, as the circuit court held
it to be, perfectly immaterial to the issue between the parties. By
the law of the State of Iowa,
"where an occupant of land has color of title thereto, and in
good faith has made any valuable improvements thereon, and is
afterwards, in a proper action, found not to be the rightful owner
thereof,"
he is entitled to payment or credit for the value of his
improvements. Code of Iowa, secs. 1976-1981. The effect of this
statute is to make such an occupant practically the owner of his
improvements, even though he be not the owner of the land on which
they have been made. If, therefore, the title to the land had been
shown to be in the defendants, the proof would not have affected
the right of the plaintiff to recover compensation for willful or
negligent destruction of the buildings and lumber. Nor could it
have changed the degree of prudence and care which the defendants
were bound to exercise in order to guard against injury to that
property. The plaintiff is not to be regarded as a mere trespasser,
wantonly thrusting himself or his property in the way of danger --
a trespasser to whom the defendants owed a less degree of caution
than would have been due if he had been the undisputed owner of the
fee simple of the land on which the mill stood. We cannot admit
that the defendants owed no duty to the plaintiff, even if he was
occupying their land without their consent. An attempt was made
during the argument to maintain that they had been found by the
jury guilty only of an act of omission, and it was insisted that
such an act would not give a right of action to the plaintiff if he
was wrongfully in possession of their land. Neither the fact
asserted nor the inference drawn from it can be conceded. The
verdict of the jury was, 1st, that the elevator was burned from the
steamer
Jennie Brown; 2d, that such burning was caused by
not using ordinary care and prudence in landing at the elevator,
under circumstances existing at that particular time; and 3d, that
the burning of the mill and lumber was the unavoidable consequence
of the burning of the elevator.
Page 94 U. S. 472
The only reasonable construction of the verdict is that the
fault of the defendants -- in other words, their want of ordinary
care and prudence -- consisted in landing the steamer at the
elevator in the circumstances then existing, when a gale of wind
was blowing towards it, when the elevator was so combustible and so
tall. If this is not the meaning of the verdict, no act of
negligence, of want of care, or of fault has been found. And this
is one of the faults charged in the declaration. It averred that
while the wind was blowing a gale from the steamboat towards and in
the direction of the elevator, the defendants carelessly and
negligently allowed, permitted, and counseled (or, as stated in
another count, "directed") the steamboat to approach and lie
alongside of or in close proximity to the said elevator. This is
something more than nonfeasance; it is positive action, the result,
consequence, or outworking, as the jury have found it, of the want
of such care as should have been exercised.
It has been further argued in support of his assignment of error
that the proffered proof of title should have been admitted,
because it tended to show contributory negligence on the part of
the plaintiff. But we cannot understand how it could have had any
such tendency. Whether the mill stood on the defendants' land, or
on other land equally distant from the steamer and elevator, and in
the same direction, its exposure to the fire was exactly the
same.
A second exception taken in the court below and here insisted
upon is that the court refused to permit the defendants to prove by
witnesses who were experts, experienced in the business of fire
insurance, and accustomed by their profession to estimating and
calculating the hazard and exposures to fire from one building to
another, and to fixing rates of insurance, that, owing to the
distance between the elevator and the mill and the distance between
the elevator and the lumber piles, the elevator would not be
considered as an exposure to the mill or lumber, and would not be
considered in fixing a rate thereon, or in measuring the hazard of
mill or lumber.
This exception is quite unsustainable. The subject of proposed
inquiry was a matter of common observation upon which the lay or
uneducated mind is capable of forming a judgment.
Page 94 U. S. 473
In regard to such matters, experts are not permitted to state
their conclusions. In questions of science, their opinions are
received, for in such questions scientific men have superior
knowledge and generally think alike. Not so in matters of common
knowledge. Thus, it has been held that an expert cannot be asked
whether the time during which a railroad train stopped was
sufficient to enable the passengers to get off,
Keller v.
Railroad Company, 2 Abb. (N.Y.) App.Dec. 480, or whether it
was prudent to blow a whistle at a particular time,
Hill v.
Railroad Company, 55 Me. 438. Nor can a person conversant with
real estate be asked respecting the peculiar liability of
unoccupied buildings to fire.
Muloy v. Insurance Company,
2 Gray (Mass.) 541. In
Durell v. Bederly, Chief Justice
Gibbs said: "The opinion of the underwriters on the materiality of
facts, and the effect they would have had upon the premium, is not
admissible in evidence." Powell's Evid. (4th ed.) 103. And in
Campbell v. Richards, 5 Barn. & Ad. 846, Lord Denman
said:
"Witnesses are not receivable to state their views on matters of
legal or moral obligation, nor on the manner in which others would
probably be influenced, if the parties had acted in one way rather
than in another."
See also Lord Mansfield's opinion in
Carter v.
Boehm, 3 Burr. 1905, 1913, 1914, and
Norman v.
Higgins, 107 Mass. 494, in which it was ruled that in an
action for kindling a fire on the defendant's land so negligently
that it spread to the plaintiff's land and burned his timber, the
opinion of a person experienced in clearing land by fire that there
was no probability that a fire set under the circumstances
described by the witnesses would have spread to the plaintiff's
land was inadmissible.
The next exception is to the refusal of the court to instruct
the jury as requested, that
"if they believed the sparks from the
Jennie Brown set
fire to the elevator through the negligence of the defendants, and
the distance of the elevator from the nearest lumber pile was three
hundred and eighty-eight feet, and from the mill five hundred and
twenty-eight feet, then the proximate cause of the burning of the
mill and lumber was the burning of the elevator, and the injury was
too remote from the negligence to afford a ground for a
recovery."
This proposition the court declined to affirm, and in lieu
thereof
Page 94 U. S. 474
submitted to the jury to find whether the burning of the mill
and lumber was the result naturally and reasonably to be expected
from the burning of the elevator; whether it was a result which
under the circumstances would naturally follow from the burning of
the elevator, and whether it was the result of the continued effect
of the sparks from the steamboat without the aid of other causes
not reasonably to be expected. All this is alleged to have been
erroneous. The assignment presents the oft-embarrassing question
what is and what is not the proximate cause of an injury. The point
propounded to the court assumed that it was a question of law in
this case, and in its support the two cases of
Ryan v. New York
Central Railroad Co., 35 N.Y. 210, and
Kerr v.
Pennsylvania Railroad Co., 62 Penn. St. 353, are relied upon.
Those cases have been the subject of much criticism since they were
decided, and it may perhaps be doubted whether they have always
been quite understood. If they were intended to assert the doctrine
that when a building has been set on fire through the negligence of
a party, and a second building has been fired from the first, it is
a conclusion of law that the owner of the second has no recourse to
the negligent wrongdoer, they have not been accepted as authority
for such a doctrine even in the states where the decisions were
made.
Webb v. The Rome, Watertown & Ogdensburg Railroad
Co., 49 N.Y. 420, and
Pennsylvania Railroad Co. v.
Hope, 80 Penn.St. 373. And certainly they are in conflict with
numerous other decided cases.
Kellogg v. Chicago &
Northwestern Railroad Co., 26 Wis. 224;
Perley v. Eastern
Railroad Co., 98 Mass, 414;
Higgins v. Dewey, 107
id. 494;
Tent v. Toledo, Peoria, & Warsaw Railroad
Co., 49 Ill. 349.
The true rule is that what is the proximate cause of an injury
is ordinarily a question for the jury. It is not a question of
science or of legal knowledge. It is to be determined as a fact in
view of the circumstances of fact attending it. The primary cause
may be the proximate cause of a disaster, though it may operate
through successive instruments, as an article at the end of a chain
may be moved by a force applied to the other end, that force being
the proximate cause of the movement, or as in the oft-cited case of
the squib thrown in the marketplace.
Page 94 U. S. 475
2 Bl. Rep. 892. The question always is Was there an unbroken
connection between the wrongful act and the injury, a continuous
operation? Did the facts constitute a continuous succession of
events so linked together as to make a natural whole, or was there
some new and independent cause intervening between the wrong and
the injury? It is admitted that the rule is difficult of
application. But it is generally held that in order to warrant a
finding that negligence, or an act not amounting to wanton wrong,
is the proximate cause of an injury, it must appear that the injury
was the natural and probable consequence of the negligence or
wrongful act and that it ought to have been foreseen in the light
of the attending circumstances. These circumstances, in a case like
the present, are the strength and direction of the wind, the
combustible character of the elevator, its great height, and the
proximity and combustible nature of the sawmill and the piles of
lumber. Most of these circumstances were ignored in the request for
instruction to the jury. Yet it is obvious that the immediate and
inseparable consequences of negligently firing the elevator would
have been very different if the wind had been less, if the elevator
had been a low building constructed of stone, if the season had
been wet, or if the lumber and the mill had been less combustible.
And the defendants might well have anticipated or regarded the
probable consequences of their negligence as much more far-reaching
than would have been natural or probable in other circumstances. We
do not say that even the natural and probable consequences of a
wrongful act or omission are in all cases to be chargeable to the
misfeasance or nonfeasance. They are not when there is a sufficient
and independent cause operating between the wrong and the injury.
In such a case, the resort of the sufferer must be to the
originator of the intermediate cause. But when there is no
intermediate efficient cause, the original wrong must be considered
as reaching to the effect, and proximate to it. The inquiry must
therefore always be whether there was any intermediate cause
disconnected from the primary fault, and self-operating, which
produced the injury. Here lies the difficulty. But the inquiry must
be answered in accordance with common understanding. In a
succession of dependent events, an interval may always be
Page 94 U. S. 476
seen by an acute mind between a cause and its effect, though it
may be so imperceptible as to be overlooked by a common mind. Thus,
if a building be set on fire by negligence, and an adjoining
building be destroyed without any negligence of the occupants of
the first, no one would doubt that the destruction of the second
was due to the negligence that caused the burning of the first. Yet
in truth, in a very legitimate sense, the immediate cause of the
burning of the second was the burning of the first. The same might
be said of the burning of the furniture in the first. Such
refinements are too minute for rules of social conduct. In the
nature of things, there is in every transaction a succession of
events, more or less dependent upon those preceding, and it is the
province of a jury to look at this succession of events or facts
and ascertain whether they are naturally and probably connected
with each other by a continuous sequence, or are dissevered by new
and independent agencies, and this must be determined in view of
the circumstances existing at the time.
If we are not mistaken in these opinions, the circuit court was
correct in refusing to affirm the defendants' proposition and in
submitting to the jury to find whether the burning of the mill and
lumber was a result naturally and reasonably to be expected from
the burning of the elevator under the circumstances, and whether it
was the result of the continued influence or effect of the sparks
from the boat, without the aid or concurrence of other causes not
reasonably to have been expected. The jury found, in substance,
that the burning of the mill and lumber was caused by the negligent
burning of the elevator, and that it was the unavoidable
consequence of that burning. This, in effect, was finding that
there was no intervening and independent cause between the
negligent conduct of the defendants and the injury to the
plaintiff. The judgment must therefore be affirmed.
Judgment affirmed.
