Would the evidence offered and excluded tend to establish the violation by plaintiff of any agreement or promise on his part contained in the lease ? The usual words of demise import a covenant for quiet enjoyment, which signifies that the tenant shall not be evicted by title paramount, and also that his possession shall not be disturbed by the acts or wrongful omissions of the lessor. Any sort of annoyance, unless, perhaps, a mere trespass, affecting the occupation of the property let, which prevents the tenant from enjoying it in as ample a manner as he is entitled to by the terms of the lease, amounts to *520a breach. If the lessor disturbs the possession by an unlawful interference therewith, the lessee may, when sued for the rent, set up the damages arising from such disturbance as a counterclaim (Hanley v. Banks (Okl.) 51 Pac. 664; McDowell v. Hyman (Cal.) 48 Pac. 984); while at common law it seems he may recoup damages (Mayor v. Mabie, 13 N. Y. 151).
