Failure of lessee to give lessor written notice ninety days in advance of the expiration of this lease, of a desire to cancel or renew same, shall be considered as evidence that said lessee desires to continue said lease in full force and effect for one year from and after the date of its expiration and be accordingly bound.
Such a renewal clause does not amount to a covenant to make a new lease; but it extends the original lease. The lessor can not, therefore, insist that the lessee execute a new lease containing a similar renewal clause. Mecklenburg Real Estate Co. v. Kyoleum Co., 142 Tenn. 295, 14 A. L R. 944, 218 S. W. 821.
