The opinion of the court was delivered, by
Agnew, J.This case cannot be well stated without a summary of the facts gathered from the evidence, and the rejected offers assigned now for error. They are about these : The basin in the Monongahela river, opposite the city of Pittsburgh, formed by the slackwater dam above the bridge and the shoals below the city, is filled with shipping; the wharf from the bridge to the point being lined with coal-boats, canal-boats and steamboats, and perhaps some other craft. On the south side of the river, for a mile or more below the bridge, the shore, is occupied by boats at different points.-
The coal trade of Pittsburgh with the country below on the Ohio and Mississippi is very great, amounting to millions of bushels. It is carried on chiefly in large barges or flats, very deep, broad and unwieldy, carrying from eight to eleven thousand bushels in each. Those coming chiefly down the slackwater, after passing through the locks, are collected in fleets in front of the city, and moored in convenient and safe places to await freshets in the river to carry them out, called coal-boat rises. About twelve feet over the bars is considered a good coal-boat rise. They arc then taken in tow by a steam coal-tug and floated to market below. Safety of moorage would seem, therefore, to be a matter of moment to the shipping filling that basin, and confined to it in low stages of water.
The defendant, being engaged in the coal trade, had a fleet of barges laden with coal lying moored at and fastened to one of the piers of the bridge, between five and six hundred feet from the southern shore, where a strong current prevails in a coal-boat rise.
*441While so moored one of his barges sprang a leak, and sunk so rapidly after discovery of her condition that she had to be cut loose from her lashings to prevent her carrying others down. After sinking she was carried beneath the surface downwards, and across to the south side, where she lodged beneath the plaintiff’s boats, some of which, when the water subsided, settled upon her and were sunk and injured. The action was for this injury. The cause of the leak which sunk the defendant’s barge was unknown. All that is known of it is, that when recovered she was found to have her bow planks sprung at the knuckle of the rake, opening a seam of about half an inch. The doctrine of the court below was, that as the cause of sinking was unknown, it must be presumed it happened without the defendant’s fault, and therefore that the place of moorage was immaterial, and to be excluded from the consideration of the jury. On this principle the danger of mooring to a pier out on the river where, on a rise, a strong current sets in accompanied by floating drift, was ruled out of the proof, and the court instructed the jury that their inquiry began with the conduct of the defendant when he discovered his boat was sinking ; and their question was, whether he was then guilty of negligence or carelessness in regard to something which naturally conduced to the plaintiff’s injury. The judge, with commendable fairness and clearness, planted himself squarely upon this position, both in his rulings upon the evidence and his charge, giving to the defendant every advantage he could ask for revision. The doctrine of the court negatives all duty in moorage, and throws upon others the risk of sinking there; as though it were inevitable accident, and not arising from any fault of the defendant in the selection of a place for his boats to lie. In argument it was said that no one but the bridge company could complain of his tying up his boat to their pier, and that it was as lawful to moor in the stream as at the shore. But did the defendant owe no duty to others who had the same rights of moorage in the river at that place ? If others had the same right of mooring in that basin, and many vessels were there, if these coal-barges are large, unwieldy and difficult to be handled; if owing to their size and immense tonnage of coal they are liable to accident and readily to sink; and if the place of moorage was unsafe, and likely in case of sinking to produce injury to some one else, did not a duty lie upon the defendant to avoid this place, and to seek a safer one ? The maxim sio utere tuo ut alienum non Icedas clearly applies. Where a party is dealing with a subject full of risk, greater caution and diligence are required to prevent injury by reason of it; more care is required of him who stores powder or petroleum than of him who keeps coffee or sugar. The general rule is, that a man is answerable for the consequences of a fault which are natural and probable, and might therefore be foreseen by ordinary *442forecast, while it is true that if his fault happen to concur with something extraordinary, and therefore not likely to be foreseen, he will not be answerable for the unexpected result. These principles ruled the opposite cases of Morrison v. Davis & Co., 8 Harris 171, and Scott v. Hunter, 10 Wright 192. In the latter case, which in principle resembles the one before us, it is said that the maxim causa próxima non remota spectatur is difficult of application, and that it is impossible to draw a line between causes of injury such as are sufficiently proximate and those too remote to be the foundation of an action.
The same doctrines were held by Black, C. J., in The City of Pittsburgh v. Grier, 10 Harris 54. The city of Pittsburgh having the control and receiving revenue from a wharf, suffered a pile of iron to lie near the water’s edge for a length of time, forbidden by its ordinance, and a steamboat having landed at a reasonable stage of water, was forced by a rise in the river upon the pile of iron, to avoid which she was backed into the stream, and there was struck by a floating boat or raft and sunk. It was held that the city was liable for negligence in not removing the iron, and that the cause of injury by the floating body, in the stream, was not so remote as to shift the loss from the city. The Chief Justice saying, it is not the law that men are responsible for their negligence only to the extent of the injuries which they knew would flow from it. If it were, there could be no recoveries except for malicious wrongs.
In Beach v. Parmeter, 11 Harris 196, the present' Chief Justice remarking upon an injury by collision, said that “for inevitable accidents, and for such as result from mutual negligence of parties, the law gives no redress; but when the injury comes from the exclusive negligence of one party, he cannot shield himself from liability by calling it an accident.” The maxim causa próxima non remota spectatur means but this. We are not to link together as cause and effect, events having no probable connection in the mind, and which could not by prudent circumspection and ordinary thoughtfulness be foreseen as likely to happen in consequence of the act in which we are engaged. It may be true that the injury would not have occurred without the concurrence of our act with the event which immediately caused the injury, but we are not justly called to suffer for it unless the other event was th§ effect of our act, or were within the probable range of ordinary circumspection when engaged in the act.
But when we are engaged in an act which the surrounding circumstances indicate may be dangerous to others or their interests, and when the event whose concurrence is necessary to make our act injurious, is one which we can readily see may occur under these circumstances, and unite with the act to inflict an injury, we are culpable if we do not take all the care which prudent cir*443cumspection would suggest to avoid the injury. This may be illustrated by the case instanced in criminal law, where a workman throws a stick of timber from the top of a building into a street. If it be-in the unfrequented street of a small village, and he gives loud warning to any who might chance to pass by, he will not be held guilty of felonious homicide. But if he should cast it into the street of a populous city, where many are passing, and death ensue, he would be guilty of the homicide, notwithstanding his cry of warning. He cannot claim it to be an accident, but is taught by the circumstances themselves that the presence of passers is probable, and that it is improbable every one would hear his warning, or hearing understand it. He would be held to greater care, and to see that there were no one beneath. Accountability for civil injuries is even greater than for criminal acts. The cases of Morrison v. Davis & Co., and Scott v. Hunter, also furnish illustrations. In the former the injury happened because the boat chanced to be near a dam, when the flood came and carried it over, causing the loss of the goods. The alleged fault in the carrier was his using a lame horse, causing^a delay which chanced to bring the boat to the dam when the flood overtook it, otherwise the dam, and with it the danger, would have been passed.
While it is evident the delay caused by the lameness was by its concurrence with the flood an element in the cause of loss, yet the occurrence of the flood, the immediate cause of injury, just then and there, was not within the circle of probable foresight. Hence the maxim causa próxima non remota spectatur, had its proper application. In Scott v. Hunter it was also the concurrence of a fortuitous flood with the act of the defendant which swept the boat over the dam; and yet he was held to be liable. Why the difference ? It appears to be this. The act of the defendant was directly connected with the condition of the stream, which was a circumstance to give warning and lead his mind to perceive the danger. He wrongfully and unnecessarily continued to obstruct the entrance to the locks, and thereby held the plaintiff’s boats out in the stream. He knew that others had an equal right to enter each in his turn. He knew that the stream was liable to floods by the fluctuations of the weather, and that the weather is unstable. He was therefore warned by the circumstances that an undue continuance in the entrance exposed the plaintiff’s boat to danger if a flood came. He had reason to apprehend injury from his wrongful act. While the flood was therefore fortuitous in this instance, as well as in the former, yet he was reasonably led to know it might happen, and if it did, that his own act would be likely to injure those whom it exposed to the action of the swollen current.
The same principle may be applied to the case before us, *444according to the character of the facts which may be found by the jury. Had there been no harbor or basin filled by numerous boats, moored all along the wharf, and opposite shore, his mooring his fleet in the current exposed to accident there, and his want of wisdom or danger in mooring there, would not connect itself with probable danger to others. It would scarcely be expected that a sunken boat at the pier would be moved across the current to the spot where only a few boats lay, and lodge beneath them. It could not readily he held that his act would lead to probable injury to any but himself. But if he knew he was mooring his fleet of boats in a harbor contracted by low water into a limited basin, where many others lay, — if he knew that such barges filled with coal are ponderous, unwieldy, and difficult of control, are liable to injury, and easily sunken, and that the place of mooring, by reason of the strength of the current and floating drift, was one of danger, and most likely to cause such boats to sink, and also knew that this place, in case of the-sinking of his boats, was likely to prove to be dangerous to some of the many boats lying below, and that the] flood would come — for it was his purpose to await its coming, to carry him out — it could scarcely be held that these circumstances did not indicate to his mind the greater danger of mooring there, and if an accident should happen, the danger to which it would expose others. The injury under such circumstances would not be so remote that it ought not to be taken into account.
But it must be observed that these are inferences of fact which belong to the jury, whose province it is to determine what are the circumstances and the inferences of probability to be drawn from them.
We think, therefore, the court erred in withholding from the jury all the evidence as to the place of mooring the fleet, and in charging them that, -whether the defendant was careful or careless, wise or foolish, in mooring at the pier, no negligence could be imputed to him, because the' cause of injury to his barge was not explained, and that the sinking of it in the absence of proof must be presumed to be without fault on his part. We are not to be understood as expressing our opinion upon the propriety or safety of mooring boats at the pier, or its probable consequences. There may be difficulty in determining the facts which can be solved only by the testimony of those who understand these matters well.
But -we decide that the court erred in excluding all the evidence upon this branch of the case, and in confining the jury to a single view of it.
The judgment is reversed, and a venire facias de novo awarded.
