Barney Google's horse Spark Plug loses the race he's in. He loses it so badly he crosses the finish line the next morning. In his next race, however, he's the sole competitor to Triple Crown winner Man o' War.
The copy of this cartoon seems to have been taken from the black-and-white check print, and colorized with a very primitive scheme. In addition, there are problems with the fact that Barney Google and his regular cast of characters have been designed strictly after the comic strip, while the background work and the animation of the background and Man o' War seems to have been designed in a much more sophisticated manner. The result is bizarre.
