delivered the opinion of the court.
Appellee erected a dam and constructed a saw and gristmill on Little Laurel river, a nOn-navigable stream. Prior to this, appellant Tye was the owner of a saw-mill, run by the water power of the same stream, and located about one. mile below the dam and mill of appellee. Shortly after appellee’s mill had gone into operation, appellant repaired his. dam, and, as charged by plaintiff appellee here, ‘ ‘ unlawfully raised it higher than it was at the time of defendant’s purchase or any time prior thereto,” and that by reason of the increased height of the dam the water was caused to flow *465back on the wheel of appellee’s mill, thereby doing him great damage. The prayer of the petition is for damages, and that appellant Tye be compelled to lower the dam to its former height. Afterwards appellant Jackson purchased the Tye mill, and, by amended petition, was made a party defendant, and damages' sought against him for continuing the dam at the height to which it had been raised by Tye, and a decree sought, as in the original petition, for lowering the dam to the height it was when purchased by Tye. The answer of the appellants denied the allegations of the petition, and upon hearing, the court adjudged damages against both appellants, and decreed that the dam be lowered twelve inches.
The only question we think proper to consider is, whether the petition and amended petition set forth a cause of action against either Tye or Jackson.
The rule in equity is, that the statement of the cause of action should be set forth with such particularity as to enable the chancellor, from an inspection of the petition alone, to grant the relief sought. If the petition is not so specific, there can be no decree, by default, on failure of the defendant to controvert the matter set up; nor can there be a decree, after pleading over by -the defendant, unless the answer is of such a nature as to. cure the defect in the petition, and, when taken in connection with the petition, to show the relief sought and the right of the plaintiff thereto. In such a case, in order that the answer may possess such curative properties, it must supply the missing averments in the petition, without which it would be fatally .defective. There are also cases in which it has been held, after judgment, that a simple denial in the answer of the existence of *466the material facts omitted from the petition cures the defect; but that is where the parties have manifestly gone to trial upon an issue thus presumed to be formed, and their substantial rights have been intelligently investigated and determined. (Pomeroy on Remedies and Remedial Rights, sec. 579; Bliss on Code Pleading, sec. 437; Chitty on Pleading, vol. 1, page 703; Louisville and Portland Canal Company v. Murphy, 9 Bush, 525.)
In the case under consideration the petition fails to allege the height of the dam at any time prior to the building of appellee’s dam and mill, and also fails to state how much appellant Tye added to the height of his dam. The last mentioned allegation was undoubtedly essential to present an issue, and to enable the court to decree in conformity to the prayer of the petition. No decree could have gone if no answer had been filed, and as the answer simply denies the allegations of the petition, and does not, expressly or by implication, supply the omitted allegations of the petition, the defect is not cured.
Appellants and their vendors having acquired, by previous occupancy, the right to the use of the stream for the necessary purpose of the mill, as erected and used prior to the time appellee built his dam and mill, they had a right to so •continue, and appellee’s right to the use of the stream for mill purposes was subordinate to theirs. (Angel on Water Powers, sections 130 and 360.)
The other objections suggested to the petition are mainly formal, and need not be mentioned in detail. They were cured by the answer and judgment so far as constituting reversible errors on this appeal.
For the reasons given, the judgment against both Tye .and Jackson, directing that the dam be lowered, is errone*467•ous; and the judgment against them for damages, being .mainly an incident to the right in appellee to have the dam reduced in height, is also unauthorized.
Judgment reversed, and cause remanded, with directions for further proceedings consistent with this opinion.
