We are of opinion that the plaintiff is entitled to recover, but as we have not heard any argument as to the amount, we are not able to give judgment for what damages. The parties probably will empower their counsel to agree on the amount of damages; should they differ on the principle the case may be mentioned again.

Judgment for the plaintiff.

Rylands and Horrocks brought error in the House of Lords against the judgment of the Exchequer Chamber, which had reversed the judgment of the Court of Exchequer.

[Arguments omitted.]

The Lord Chancellor (Lord Cairns). My Lords, in this case the plaintiff (I may use the description of the parties in the action) is the occupier of a mine and works under a close of land. The defendants are the owners of a mill in his neighborhood, and they proposed to make a reservoir for the purpose of keeping and storing water to be used about their mill upon another close of land, which, for the purposes of this case, may be taken as being adjoining to the close of the plaintiff, although in point of fact some intervening land lay between the two. Underneath the close of land of the defendants on which they proposed to construct their reservoir there were certain old and disused mining passages and works. There were five vertical shafts and some horizontal shafts communicating with them. The vertical shafts had been filled up with soil and rubbish, and it does not appear that any person was aware of the existence either of the vertical shafts or of the horizontal works communicating with them. In the course of the working by the plaintiff of his mine he had gradually worked through the seams of coal underneath the close, and had come into contact with the old and disused works underneath the close of the defendants.

In that state of things the reservoir of the defendants was constructed. It was constructed by them through the agency and inspection of an engineer and contractor. Personally, the defendants appear to have taken no part in the works, or to have been aware of any want of security connected with them. As regards the engineer and the contractor, we must take it from the case that they did not exercise, as far as they were concerned, that reasonable care and caution which they might have exercised, taking notice, as they appear to have taken notice, of the vertical shafts filled up in the manner which I have mentioned. However, my Lords, when the reservoir was constructed and filled, or partly filled, with water, the weight of the water bearing upon the disused and imperfectly filled-up vertical shafts, broke through those shafts. The water passed down them and into the horizontal workings, and from the horizontal workings under the close of the defendants it passed on into the workings under the close of the plaintiff, and flooded his mine, causing considerable damage, for which this action was brought.

The Court of Exchequer, when the special case stating the facts to which I have referred was argued, was of opinion that the plaintiff had established no cause of action. The Court of Exchequer Chamber, before which an appeal from this judgment was argued, was of a contrary opinion, and the judges there unanimously arrived at the conclusion that there was a cause of action, and that the plaintiff was entitled to damages.

My Lords, the principles on which this case must be determined appear to me to be extremely simple. The defendants, treating them as the owners or occupiers of the close on which the reservoir was constructed, might lawfully have used that close for any purpose for which it might in the ordinary course of the enjoyment of land be used; and if, in what I may term the natural user of that land, there had been any accumulation of water, either on the surface or under ground, and if, by the operation of the laws of nature, that accumulation of water had passed off into the close occupied by the plaintiff, the plaintiff could not have complained that that result had taken place. If he had desired to guard himself against it, it would have lain upon him to have done so by leaving, or by interposing, some barrier between his close and the close of the defendants in order to have prevented that operation of the laws of nature.

As an illustration of that principle, I may refer to a case which was cited in the argument before your Lordships, the case of Smith v. Kenrick, in the Court of Common Pleas, 7 C. B. 515.

On the other hand, if the defendants, not stopping at the natural use of their close, had desired to use it for any purpose which I may term a non-natural use,[[287]] for the purpose of introducing into the close that which in its natural condition was not in or upon it, for the purpose of introducing water either above or below ground in quantities and in a manner not the result of any work or operation on or under the land; and if in consequence of their doing so, or in consequence of any imperfection in the mode of their doing so, the water came to escape and to pass off into the close of the plaintiff, then it appears to me that that which the defendants were doing they were doing at their own peril; and if in the course of their doing it the evil arose to which I have referred, the evil, namely, of the escape of the water and its passing away to the close of the plaintiff and injuring the plaintiff, then for the consequence of that, in my opinion, the defendants would be liable. As the case of Smith v. Kenrick is an illustration of the first principle to which I have referred, so also the second principle to which I have referred is well illustrated by another case in the same Court, the case of Baird v. Williamson, 15 C. B. N. S. 317, which was also cited in the argument at the Bar.
