It is well settled that the plea of payment is an affirmative one, and the general rule is that the burden of showing payment must be assumed by the party interposing it. Davis v. Dockery, 209 N.C. 272, 183 S.E. 396; Furst v. Taylor, 204 N.C. 603, 169 S.E. 185; Collins v. Vandiford, 196 N.C. 237, 145 S.E. 235; Swan v. Carawan, 168 N.C. 472, 84 S.E. 699. See also Joyce v. Sell, 233 N.C. 585, 64 S.E.2d 837; 8 Am.Jur., Bills and Notes, Sec. 1035; 40 Am.Jur., Payment, Sec. 278. The burden of proof is a substantial right. Davis v. Dockery, supra; Collins v.
