Appellee insists that the points now made by appellants were involved in the ruling on the demurrer, and that such-ruling must be accepted as the law of the case. In filing an amendment to the petition after the demurrer was sustained, the plaintiffs necessarily waived any error in the ruling. Long v. Furnas,
being a repetition of matter, in so far as material, contained in the petition, and this had been sustained, the case would be parallel with Long v. Furnas, supra, and the ruling on the demurrer must have been accepted as the law of the case. But the defendant filed no motion to strike, nor demurrer. He answered specifically and in detail the allegations of the original petition and amendments thereto as
The rule has been applied in a great variety of cases. A leading authority is Lampman v. Milks,
These decisions illustrate the circumstances under which the rule will be applied, and under which the right to the continuance of prevailing conditions will pass with the deed to a portion of an owner’s estate. The test to be applied is whether the owner before conveying had created a condition in or added advantages to the portion of his property conveyed reasonably essential to its continual enjoyment or beneficial use and in some way dependent on the part retained. The principle is somewhat too broadly stated in Farnham on Waters and Water Eights, section 831: “ If the owner of land has artificially created upon the property a condition which is favorable to one portion of his property, and then sells that portion, the grantee will take it with the right to have the favorable condition continued.” See, also, Forrest Mill Co. v. Cedar F. M. Co.,
But the water level had been maintained by the owners of this dam for more than forty years, and, as was well known to the grantors, the value of the land conveyed to plaintiff depended on the continuance of conditions then prevailing, and it was purchased in reliance thereon. Por them after selling it to have altered these conditions by the removal of the dam or to sell to another-for that purpose, under the circumstances, would be an act of bad faith not to be tolerated. Men ought not to be allowed thus to trifle with the confidence of those with whom they deal. True there was no express representation or assurances that the dam would not be destroyed. But from the execution of the deed of this tract, which had long been occupied by the tenants, in connection with the pond produced by the dam, for the purpose of their business and the value of which, owing to the facilities for conducting the ice business, depended upon its continuance, all of which was open and apparent, together with the fact that the dam had been maintained for a period beyond that of the statute of limitations, it is plainly to be inferred that the conveyance was made with reference to existing conditions. In a sense the dam’is to be regarded as temporary, for artificial means will be essential for- its effectual maintenance. Kray v. Muggle, 77 Minn. 232 (79 N. W. 964, 1026, 1064, 45 L. R. A. 218) ; Burrows v. Lang, (1901) 2 Ch. 502. But from its long continuance and use at the time in furnishing water power for the mills the intention that it should be perpetual was the only natural inference, and, for this reason, as be
. Appellee rightly contends that in a case like this, as the grantee has not been in possession the statutory period, the doctrine of reciprocal rights as between the owner of the dam, the right to maintain which has been acquired by prescription, and those of the riparian owners to its continuance, has no direct application. See Kray v. Muggle,
Moreover, the right of appellants to maintain and repair is not now necessary to be determined, for all that was sought by the temporary writ was to prevent the destruction of the dam. But the grant of an easement usually carries with it whatever is essential to its enjoyment, and if this be so in this case the conveyance conferred on the owner of the dormant estate the right to repair and rebuild the dam.
