The Earliest Cherry
By further experiments in selective breeding, Mr. burbank has developed a cherry that is even earlier than the one that bears his name. This new cherry is of handsome form and color and a profuse bearer, as the illustration shows. These is, of course, a limit to the development of the habit of early bearing, but what this limit is can be determined only by long series of experiments in selective breeding. Mr Burbank is constantly on the lookout for individual fruits that show peculiar qualities, and these are carefully preserved as material for further experiments.
