Avie was the maker of a promissory note and Skinner was an endorser. Avie defaulted on the note and Skinner was found and served. Skinner claimed he was illiterate but had authorized his mark on the note, but he did not intend to obligate himself as an endorser. Skinner was an illiterate French-speaking Negro, and there was controversy about whether Skinner understood what and why he was affixing his mark to the note. Judgment was rendered for Skinner and St. Landry Loan Co. (P) appealed.
