The proposition mainly relied on is that inasmuch as plaintiff never re-entered for breach of condition, no forfeiture occurred. No doubt the usual mode of *264enforcing a forfeiture of a term is by re-entry, which may take the form of an unláwful detainer or an ejectment action; and according to the most recent decisions any act of the lessor which unequivocally manifests his intention to claim a forfeiture and demand possession, will be equivalent to a re-entry. Such acts are giving another lease of the premises or demanding possession under circumstances which, if the demand was complied with, would at once restore possession to the lessor. [Alexander v. Hodges, 41 Mich. 691; Kramer v. Amberg, 53 Hun 427; Guffy v. Hukill, 34 W. Va. 49; Read v. Tuttle, 35 Conn. 25; 18 Am. and Eng. Ency. Law (2 Ed.), sec. 382; Jones, L. & T., secs. 483, 485.] In the present case the lease itself provided how a forfeiture should be worked. It said any violation of a covenant or agreement by the lessee should produce or work a forfeiture, if so determined by the lessor by notice in writing served on the lessee by delivering to him a copy. We have not set out the declaration of forfeiture, but it was in writing, elaborate and unequivocal in its terms, and in form and substance conformed to the requirement of the lease. As the clause of the lease which prescribed the mode of determining a forfeiture for breach of a condition was followed strictly by the plaintiff, we hold it sufficed to end the term and justified defendant in treating it as ended without waiting to be turned out by legal process. In other words, he was justified in making an arrangement for other quarters on receipt of plaintiff’s notice to quit and in vacating the leasehold as soon as he could.
