“According to the weight of authority in the adjudged cases, a lease for a term from year to year so long as the lessee wanted the land is a present demise, and the lessees remaining in posession is an extension of the lease without renewal or without notice. A dis* tinction is sometimes .recognized between a covenant to. renew a lease, and a provision for an extension of the term at the option of the lessee. (Brown v. Samuels, 24 Ky. Law Rep., 1216.) But we apprehend that the intention of the parties to the instrument is the controlling thing. If they contemplated that a new lease was to be executed before the lessee would have the right to retain the premises beyond the original term, then such renewal ought to be executed. But if their intention was that the lessee should have the right to retain the premises after the expiration of the original term, but upon the same terms of payment, and so forth, without the necessity of entering into a new lease, then of course the matter should be alowed to go that way. The office of judicial construction is simply to arrive at and effectuate the original intention of the parties as evidenced by their document.”
