delivered the opinion of the court.
The numerous authorities cited by the defendant’s counsel establish in his favor the first two propositions presented in the statement. As the law discourages perpetuities, it does not favor covenants for continued renewals ; but, when they are clearly made, their binding obligation is recognized and will be enforced. The covenant for renewal is only an incident to the lease, and as it can not be passed without the principal, the conveyance of the principal by a proper description will necessarily carry the incident. They are inseparable, and a right of action can not exist in favor of a person claiming the benefit of the covenant without any right to the possession of the leasehold; but the covenant, being annexed to the estate, runs with it, and can not be retained by itself or assigned or severed so as to give an independent cause of action. A sale of the land under execution will pass to the purchaser all the covenants that run with it as effectually as if he had received a conveyance from the lessee; for as the purchaser, after he acquires possession, is bound to pay the rent and in that way assumes the burdens of the lease, he has the right to take advantage of the covenants that touch and concern the thing demised, which enhance the value of the estate.y
