In this case a verdict for the plaintiffs was set aside by the trial court.

In brief, the record discloses an action upon the common counts with the general pleas of never indebted and set off. The original claim is for the balance upon an advance by cotton brokers, less credits for cotton shipped. At the trial the defendant offered to prove that the broker had violated instructions by holding the cotton until the market dropped, thus causing the deficit; the evidence was *255rejected as not being within the issues, whereupon the defendant tendered pleas setting up specifically these facts, but permission to file them was refused, and the refusal made a ground of motion for new trial upon the directed verdict.

We think the court could properly revise its discretion and permit the pleas to be filed. While perhaps, strictly speaking, the general plea of set off might not include the violation of instructions, yet the failure of the plaintiffs to make timely objections to the cross-interrogatories propounded to them along this line, reserving such objections to the trial avoids the laches that might otherwise be imputed to the defendant in failing to discover the narrowness that might restrict the issues open to him. Upon this writ of error we need-go no farther, but affirm the order.
