When Noel Sickles gave up his strip, Scorchy Smith, it was because of a combination of "restlessness, deadlines, boredom and money," according to biographer Bruce Canwell. In an online excerpt of an interview from The Comics Journal #242, Sickles himself mentions that his salary at the beginning of his three-year stint on the strip was $47.50 per week. In spite of his managing to negotiate it to a respectable $125 a week, Sickles quit the strip in 1936 to pursue a career in magazine illustration.
