Opinion by

The only question attempted to be raised by the assignments of error is as to the jurisdiction of the justice of the peace. It does not affirmatively appear that this question was raised in the court below. Neither the charge of the court nor any of the rulings upon evidence were excepted to by the defendants. Therefore, the question is to be determined by the record proper, of which, for present purposes, the evidence and the charge form no part: Greenawalt v. Shannon, 8 Pa. 465; Hoffman v. Dawson, 11 Pa. 280; Funk v. Ely, 52 Pa. 442. The plaintiff’s demand as shown by the transcript from the docket of the justice of the peace, “ was for $300, for breach of contract on the sale of real estate which the defendants agreed to pay the plaintiff for making a sale of certain real estate in the borough of Portland if said sale was made by March 24, 1894.” The defendant’s argument is based on the assumption that the plaintiff’s *191demand accrued, if at all, on March 24,1894; therefore, the interest which accrued thereafter swelled the demand beyond the amount of which justices of the peace have jurisdiction. Talcing a very strict view of the demand, asset forth on the docket of the justice, it may well be doubted whether it is necessarily to be inferred that the money was due and payable on March 24, 1894. But granting that it was, the plaintiff was not bound to claim interest, and the fair interpretation of the record is that he did not claim it. Interest is an incident of a debt overdue, which a party may claim or not, at his pleasure. “ A nonclaim of the interest is very unlike a voluntary reduction of the principal. The one is the absence of the assertion of claim, and the other is the actual throwing away a portion of a fixed or settled claim or demand. It will not be contended that a party may not refuse to claim interest if he does not choose to claim it, or that he may not omit to press an item of claim:" Evans v. Hall, 45 Pa. 235. See also Bower v. McCormick, 73 Pa. 427, 430, and Wood v. Lovett, 1 Penny. 51. We are of opinion that the ease comes fairly within the foregoing ruling.

Judgment affirmed..
