Film recording of a controversial boxing match with the first black heavyweight champion fighting a white retired former champion.

James J. Jeffries throwing the medicine ball. An absolutely perfect picture of the champion heavyweight of the world.

Another fine picture of the champion going through his side-stepping tactics which have made him famous. The picture ends with a wrestling bout with his brother, Jack Jeffries.

Jeffries walks into his gymnasium at Oakland, Cal., accompanied by Billy Delaney, and begins exercising with the heavy weights. The view was taken with the champion close to the camera, and during the exercises his back is turned to the audience, when his great muscles stand out in bold relief, and, as he strains and tugs at the weights, they give one the impression of huge bands of knotted cords.

A splendid subject, showing the champion heavyweight of the world, exercising in his training headquarters. After showing his skill in side-stepping, and fancy steps while skipping the rope at a phenomenal speed, the champion's trainers peel off his sweater and give him a rubdown, during which the mighty muscles on the champion's chest and back are seen to perfection.

A fine picture of the champion and his brother in a very lively one-round sparring bout. The muscles of the champion are shown to excellent advantage, and aside from being a very lively and interesting sparring exhibition the film presents an absolutely perfect photograph of the champion and his brother.

Shot against a painted backdrop of river with town on other bank & mountains behind. Throwing medicine ball while group of men watch, at least one black. He stands up & gets hit on head with ball.
