. This is an action of contract to recover rent oí a building in Atkinson Street in the city of Boston, which, as the plaintiff alleges, the defendant occupied under a written lease. The declaration is for the quarter’s rent from July 1st 1854 to October 1st 1854.
To prove the election by the defendant to hold under the lease for the additional term of two years, the plaintiff produced evidence of the payment, after the expiration of three years, of two quarters’ rent, at the advanced rate stipulated for in the ease in case the defendant elected to hold for the additional term; the declarations of the defendant that he was so holding; and a written notice, in August 1854, by the defendant to the plaintiff to put the building in repair, and that he should hold him responsible for any injury he (the defendant) rright sustain by the plaintiff’s neglect to repair.
*5521. The defendant asked the court to instruct the jury, that “ to show an election by the lessee to hold for the additional term of two years after the expiration of the three years, it was necessary for the plaintiff to prove that the defendant so elected at the time of the expiration of the three years, and duly notified the lessor of his intention so to hold.” But the court ruled that it was sufficient for the plaintiff to prove that the defendant made the election and continued to occupy; and did not charge the jury that it was necessary for the plaintiff to prove that the election was made at the expiration of the three years, or that notice thereof was given by the defendant to the plaintiff.
Neither the instructions of the learned judge nor his omission to instruct furnish, we think, just ground of exception. No formal election or notice was necessary to the continuance of the lease for the additional term of two years. The continuing to occupy the premises, and the payment of the rent at the increased rate stipulated for in case of continuance, were the best possible evidence of the election of the defendant to avail himself of the further term. They were a declaration and an act— the expression of the wish and its execution. If before the payment of the rent for the first quarter of the new term any doubt could exist under what tenure the defendant was holding, the payment of the rent at the increased rate removed the doubt.
If it was necessary to prove that the election of the defendant was made at the time of the expiration of the three years, the evidence was ample for the purpose. He continued to occupy after the expiration of the three years. He paid the increased rent stipulated for from the time the three years expired. There is nothing in the case to indicate that at any time he claimed to occupy on any other terms.
The provision in the lease is not a mere covenant of the plaintiff for renewal; no formal renewal was contemplated by the parties. The agreement itself is, as to the additional term, a lease de futuro, requiring only the lapse of the preceding term and the election of the defendant to become a lease in prcesenti All that is necessary to its validity is the fact of election.
*553Even if notice of the lessee’s intent to continue might be insisted upon by the lessor, he clearly might waive it; and he clearly did waive it by the acceptance of the increased rent on the first days of April and July—an increase which could be predicated only upon such election by the lessee. Indeed, after the payment of the rent of July 1st and the receipt given therefor, and in the absence of evidence to control their effect, the question of the defendant’s election to continue and of the plaintiff’s assent thereto would not seem to be an open one.
2. The evidence offered by the defendant to prove that on the 1st of July 1854 the premises had become unsafe and untenantable, by reason of the undermining and settling of the partition wall by the owner of the adjoining lot, after notice by such owner to the lessor of his intention to build upon his premises, and the lessor’s omission to shore up his wall, was rightly excluded.
Under the provisions of the lease, there would be no abatement or suspension of rent because of such injury to the premises. The landlord is not ordinarily bound to keep the premises in repair; nor is there anything in this lease to create such duty. Fowler v. Bott, 6 Mass. 63. Phillips v. Stevens, 16 Mass 238. Jaques v. Gould, 4 Cush. 384. Bigelow v. Collamore 5 Cush. 226. Davis v. Alden, 2 Gray, 313. By this lease, the defendant was to restore the premises at the end of the term in as good order and condition, reasonable use and wearing thereof, fire and other unavoidable casualties excepted, as they were when he took possession. The falling of the wall, by reason of not being properly shored up, would not seem to be an unavoidable casualty. The duty of repair would be on the lessee, and not the lessor. See Jaques v. Gould, 4 Cush. 388.
3. The evidence of the custom of Boston, for the owner of the premises to shore up and secure the foundation walls of his buildings, upon notice from the adjoining owner of his intention to rebuild, was rightly rejected.
If evidence of such custom were ever admissible to affect the rights of parties under written contracts, in the case at bar it was clearly immaterial; there being no provision in the lease for *554abatement or suspension of rent by reason of the loss or destruction of the buildings from any cause.
4. The remaining objection to the verdict is, that there was a fatal variance between the declaration and the lease. We think it does not exist. The allegation, that “ the defendant elected to continue in the occupancy of the premises for the term of two years next after the term of three years mentioned in said instrument, upon the terms and provisions therein mentioned,” is, in substance and legal effect, an averment that defendant elected to hold for the term of those two years. Exceptions overruled.
