Opinion by
Mr. Justice McCollum,In this case the court below refused to grant the injunction prayed for and dismissed the bill on the ground “ that a doubt upon the question of injunction is to be decided in favor of the defendant.” It is obvious from the brief opinion of the court below that the doubt was based upon the defendant’s answer to the bill and his assurance through his counsel that he had no intention of doing that which was complained of therein, and that before any attempt was made to do it the plaintiffs should have notice on which they could apply to the court to have it prevented. On the hearing of the motion for an injunction considerable testimony was taken corroborative of the averments in the plaintiffs’ bill, but no testimony was presented on the part of the defendant, who rested his defense on bis answer and the oral statements of his counsel in court. The testimony introduced by the plaintiffs tended to show a material depreciation in the value of the property covered by their mortgage, and this depreciation was attributed by the witnesses to the digging of clay *451and the construction of a brickyard thereon. Of course, excavations and constructions of this nature may materially detract from the security the mortgagee has if the property is located in a neighborhood suited to and intended for residences.
In Martin's Appeal, 9 Atl. Rep. 490, the vendor of the land received from the vendee a purchase money mortgage. The purchaser opened sand and stone quarries on the land, and the vendor filed a bill for an injunction to restrain the waste. The answer denied the quarrying and alleged the owner was grading the land to make it more valuable. The judge of the common pleas said: “ The defendant’s theory for the excavation upon the ground may be correct, but it is speculative, and he is unfortunate in being alone in his view of the improvement of the property thereby. In the eyes of others his excavations are waste. From this the mortgagee is entitled to protection until the defendant, by reducing the amount of the mortgage, or by some other satisfactory arrangement, has sufficiently secured the mortgagee from probable loss by his experiment.” The bill and application for injunction were sustained, and on appeal to this Court the decree Avas affirmed. In Righter v. Hamilton, 10 Pa. C. C. R. 260, the court granted the injunction upon the authority of Martin’s Appeal, supra, and said that “ opening and operating a new mine or clay pit upon property where none existed at the time the mortgage was created is waste as against the mortgagee. Equity Avill, by injunction, enjoin a mortgagor from committing waste on the mortgaged premises, at the suit of the mortgagee. The mortgagee is entitled to all the protection his pledge, unimpaired, gives him. ” The cases cited are referred to because they are, to some extent at least, analogous to the case under consideration.
In the case at bar the plaintiffs’ bill and the testimony submitted in corroboration of its averments furnished ground for an injunction Avhich the court should have granted unless substantial doubt Avas raised by the defendant’s answer and his assurances through his counsel that he had “ no intention of doing that of Avhich the bill complains.” JBut, while a doubt arising from the defendant’s avowal of an intention to refrain from doing that of Avhich the plaintiffs complain may have warranted a postponement of the issuance of an injunction, it did not require a dismissal of their bill. We are of the opinion, therefore, that the *452bill should be reinstated, with leave to plaintiff to move for an injunction whenever the defendant disregards his avowed intentions in the premises.
The decree dismissing the plaintiffs’ bill is reversed with direction to the court below to reinstate the bill and hold it, with leave to the plaintiffs to move for an injunction on the defendant’s disregard of his avowed intention as above stated.
