Upon trial of the question of the extent of the defendants' reservoir right, that right has been found to be a reasonable use of the reservoir until it is drawn down four feet below the top of the dam; and such reasonable use has been found to consist in letting down not exceeding 130 cubic feet per second for ten hours each working day until that point is reached. Berry v. Hutchins, 72 N.H. 211, 214, 215; S.C., 73 N.H. 310, 312; Hutchins v. Berry, 73 N.H. 611, 613-616. Upon the trial of that question of fact, evidence as to the amount of water that could be drawn under previously existing conditions as the limit of practicable use was approached would be competent; but if the parties were engaged in a trial of the fact as to the capability of the reservoir right attached to the Pickering dam, the exclusion of evidence of measurements of the flow of the stream under a claimed reproduction of conditions existing prior to the Lake Company improvements would not be error of law. Cook v. New Durham,64 N.H. 419. The difficulty of ascertaining all the conditions which might have then affected the flow of the stream, and of determining whether they had been correctly reproduced, might be so great that an attempted investigation of the collateral question would tend to confuse rather than elucidate the issue between the parties.
Even, therefore, if the question as to the flow of the stream had *Page 227 been under investigation, the refusal of the court to fix and determine the size of gates such as existed in 1854 would not present anything for consideration here. But if the law were otherwise, the extent and capability of the reservoir having been already determined, error of law cannot be predicated upon the refusal of the court, upon the facts stated, to reopen the question and grant the plaintiff a new trial, which it is found was the object of the motion, and which must of necessity have been its purpose if any result was expected to follow the desired investigation. Hutchinson v. Railway, 73 N.H. 271, 284; Ela v. Ela, 72 N.H. 216. The plaintiff has the right, as was ruled by the superior court, to make any changes he desires which will not prevent the letting down of the amount of water which it has been determined represents the capacity of the original reservoir. While the latter finding stands, any change made by him which prevents the flowing of that amount of water, it must be conclusively presumed, is the creation of a condition different from what originally existed. As to whether there should now be a further trial and the reception of additional evidence, experimental or otherwise, the fact has been found against the plaintiff. Such finding is conclusive.
The plaintiff excepted to the refusal of the court to change the orders made and now in force for managing the water or wheels of the different mills. The only order to which objection has been made here is the third order, filed December 14, 1903. That order is objected to so far as it modifies order No. 1, filed July 25, 1902, which limited the Berry privilege to thirty-eight cubic feet per second when the water did not run over the wasteway. The modification objected to provided that the limitation of the Berry privilege should not take effect until the water fell eighteen inches below the top of the wasteway. In the original brief, the plaintiff bases his objection to the modification upon the preferential right of the gristmill. As the owner of the gristmill was not a party to the proceedings in which the order now objected to was made, and as it has since been determined that the gristmill has the right to require all the mills to shut down when the water falls six inches below the top of the wasteway (Hutchins v. Berry, 73 N.H. 603, 611, 613), the order does not affect the gristmill and there is no occasion to modify it for the protection of the gristmill right. In a brief filed since the hearing, the plaintiff objects to this modification as an invasion of his right as the owner of the leather-board mill, heretofore called the box-factory privilege.
Horne v. Hutchins, 72 N.H. 77, was a bill in equity to determine to what extent and in what manner water was actually used at the box factory, October 26, 1872, such use having been held to be the measure of the box-factory right. Horne v. Hutchins, *Page 228 71 N.H. 128, 137. In the former case it was found that, as between the sawmill and the box factory, there was no preference; that the water-wheel in the sawmill could use thirty-eight cubic feet of water and the penstock of the box factory could deliver seventeen cubic feet of water per second when the water in the pond stood at the level of the wasteway. The amount to which the Horne privilege was entitled having been determined in another case to be thirteen cubic feet per second, it was ordered that the gates to the respective penstocks be set so as to permit only thirteen, seventeen, and thirty-eight cubic feet respectively to be drawn when the water stood at the top of the dam and did not run over the wasteway. Both parties excepted to these findings, orders, and decrees. The exceptions were overruled. The decrees therefore are judgments establishing the rights of the parties. The order of December 14, 1903, removing the limitation upon the use by the Berry privilege until the water fell eighteen inches below the top of the wasteway, also provided that the stops on the Hutchins wheel or gate should remain as before. The occasion for this modification does not appear. As there was no preference between the sawmill and box factory, the plaintiff cannot complain in behalf of his leather-board mill that the sawmill is permitted to draw down the water in the pond; but if, as seems to be the effect of the existing order, the sawmill is permitted to draw down the water below the top of the wasteway without limitation as to the amount, while the plaintiff's gate is set so as to draw only seventeen feet when the water is at the top of the wasteway, it is manifest that the plaintiff will as the water falls receive less than the seventeen feet to which it has been adjudged he is entitled, and that the sawmill will receive more. In the absence of any findings sustaining the change ordered December 14, 1903, the same appears to be erroneous, and the exception to the refusal to change the same to accord with the judgment in Horne v. Hutchins, 72 N.H. 77, is sustained. As the relative right between the leather-board mill and sawmill is determined to be in the ratio of seventeen to thirty-eight, it is immaterial to the plaintiff Hutchins whether the amount taken as the measure of the rights of the two — seventeen plus thirty-eight cubic feet — is excessive as against the right of the Home privilege.
Whether justice required that the plaintiff should be permitted to amend his petition, so as to present for adjudication his right to use the water at the gristmill for other purposes, is a question of fact. The denial of the motion presents no question of law.
It was said in Hutchins v. Berry, 73 N.H. 603, 604, — a bill in equity brought by the plaintiff to determine the gristmill right, — that "in the absence of a definite specification of the amount of *Page 229 water excepted or the manner of its application to produce power, it must be understood the parties contracted with reference to the manner and extent the water was then at the date of the deed actually used for the purpose specified." It appears to be well settled that when a right exists to use a certain quantity of water, a change in the mode and objects of the use without increasing the quantity is no violation of the right. Fuller v. Daniels, 63 N.H. 395; Dow v. Edes, 58 N.H. 193, 194; Wiggin v. Wiggin,43 N.H. 561, 566; Whittier v. Company, 9 N.H. 454, 458; Johnson v. Rand,6 N.H. 22. The sole question, then, is whether by the reservation in the Colby deed the parties understood the matter reserved was merely a right to operate a gristmill, and not the right to use a certain part of the water for power. It was said in Fowler v. Kent, 71 N.H. 388, 394, that "it would require very explicit language to overcome the natural inference that a person would not accept a deed of a mill privilege subject to the condition that his water rights should become forfeited if any change was made in the manner, purpose, or place of use." But whether the question is simple or difficult, the interpretation of the Colby deed is not now before the court. The superior court has ruled that the defendants ought not now to be compelled to litigate the question. This court cannot assume that there may not be some evidence which the parties can present which will aid the interpretation. Neither can they assume that all the facts bearing upon the question have been presented in the numerous cases between the present and other parties, involving this water-power, that have been before the court. If that fact could properly be assumed, the court would not take the time to search the voluminous record in these cases, which presents many other questions, for facts that may be material upon this. If the question is to be intelligently considered, it should be presented upon a record which contains in itself all the facts which either party conceives to be material. The evidence as to the modification of the original order regulating the flow of water to the Berry privilege should have been received; and unless facts appear authorizing a change, the original order should be restored.
