      Abstract of the Decision.
    1. Landlord and tenant, § 433
      
      —what does not constitute extension of lease. There was no extension of a lease where the landlord, before the expiration of the old lease, notified the tenant by letter that he would expect prompt surrender of the premises- at the expiration of the term, as he had made a lease to another person; that possession was necessary to make needed repairs and that if the tenant remained in possession after expiration of the term he would be charged double rent; and, after expiration of the term, the tenant vacated the premises after the landlord commenced making repairs, and the subsequent tender of double rent was refused.
    2. Contracts, § 8
      
      —necessity of certainty in terms of. A contract, in order to be binding, must be definite in all its provisions.
    3. Instructions, § 118
      
      —when instruction refused as not applicable to evidence. In an action for damages for unlawfully entering upon leased premises and making repairs, an instruction that it was the tenant’s duty to vacate the premises at the time of the expiration of the lease unless the jury found from the evidence that the tenant made arrangements with the landlord whereby he was to retain possession after the expiration of the lease,, held erroneous where there was no extension or renewal of the lease.
    Lee W. Carpenter, for defendant in error.
