Time-travel continues to exercise its mesmeric fascination upon writers, readers and editors of science fiction alike. Probably because almost all of us, at one time or another, have longed greatly to visit either the future or the past.

Although Chicago is not mentioned in the book as the scene of action, the Chamber of Commerce of that city is the point round which the action centers. The Bear and the Banker are chums. The Bull is financed by the Banker in the endeavor to run the "corner" in lard, and the story derives its title from the necessity found by the Bear for the ruin of his chum the Banker, in order to upset the financial schemes of the Bull. A stirring love story threads its way through the financial excitement of the book.
Rapid, impossible novel of the moving-picture type, in which the hero, a cowboy from Arizona, comes to New York, beats up the leader of a gang of crooks and marries the daughter of a millionaire. Full of exciting situations, profanity, and crude humor.
