Plumb v. Curtis

Hanford Plumb (plaintiff) sued Lewis Curtis (defendant) to recover payment for materials Simeon Plumb allegedly bought on Curtis's behalf as his agent; Curtis admitted past agency purchases but denied this particular one. Plumb testified he would not have extended credit if Simeon were buying for himself, since he knew Simeon had poor credit, and the jury found for Plumb; Curtis appealed, challenging the admissibility of that testimony.
