The defendant leased to the plaintiffs “the basement of the old grist-mill * * * for creamery purposes,” and agreed to furnish good, satisfactory water power for running the business, and to have it ready by such a time; and in case that power failed at any time to be sufficient and satisfactory, the plaintiffs were' to furnish steam power and to pay no rent while they furnished it. The “use and full control of the above-named property” were given to the plaintiffs during the term.

There was a dam somewhat over half a mile above the grist-mill from which water then was, and for thirty or forty years had been, taken through an artificial ditch and *59a flume directly to the wheel of the mill for the purpose of operating the mill. The water power thus afforded,, if properly applied, was more than enough to operate the creamery, which, as contemplated by the lease, the plaintiffs established and carried on. Soon after they took possession and before the commission of the alleged trespass, the plaintiffs had furnished and were using steam power to operate their creamery because of the unsatisfactory application of the water power, due to the neglect of the defendant ; and at the time in question, and from about the time they took possession, the plaintiffs were'using water brought through said ditch and flume to supply their steam engine <and for washing purposes, but not directly as a power, and were claiming to occupy rent free, under the stipulations in the lease concerning the cessation of rent. The act complained of as a trespass consisted in opening the dam so that the water was diverted from the artificial channel and flowed in its natural course, the plaintiffs then being in possession of the property and rights covered by the lease, subject to which the defendant had title to the mill and the power. It is quite obvious that the lease did not convey to the plaintiffs such an interest in the locus in quo as to enable them to maintain trespass qua.. clau. for the act complained of. The lease does not purport to convey any interest therein, but only to obligate the defendant to furnish a good, satisfactory water power. The power supplied by the dam, when properly applied, was_more than sufficient to operate the creamery, and clearly the defendant had the right to use the excess to operate what remained to him of the mill, or for any other purpose, and this right and his obligation to the plaintiffs rendered it necessary that he should have the exclusive control of the dam, that he might enjoy the one and fulfill the other. This view is favored, also, by the stipulation that the plaintiffs were to occupy rent free while they had to use steam power. We therefore construe this *60to be, not a demise of the locus, but an agreement to furnish water power, for the breach of which this action is not maintainable.

Judgment affirmed.
