Spinelli v. Golda, 6 N. J. 68, 79 (1950); Jennings v. Pinto, 5 N. J. 562, 570 (1950); 3 Williston, Contracts (rev. ed. 1936), § 616, p. 1772. Where ambiguity exists, the subsequent conduct of the parties in the performance of the agreement may serve to reveal their original understanding. Journeymen Barbers, etc., Local 687 v. Pollino, 22 N. J. 389, 395 (1956). The trial judge correctly found the lease to be ambiguous with respect to the landlord’s obligation and hence admitted evidence of the parties’ practical construction of its terms. In those circumstances, it was proper to submit the issue of the meaning of the contract to the jury as one of fact.
The lease contains no clearcut promise by the tenant or landlord with respect to the repair of the defect here involved. Rather there are expressions pointing both ways. In analyzing the agreement, we should be mindful of the rule that ambiguities are to be taken most strongly against the draftsman, here the defendant. Terminal Construction Corp. v. Bergen County Hackensack River Sanitary Sewer District Authority, 18 N. J. 294, 302 (1955); Moses v. Edward H. Ellis, Inc., 4 N. J. 315, 322 (1950).
