A Bed of Four-Leaved Clover
This interesting colony of four-leaved clover grows in Mr. Burbank's yard. It is an example among hundreds of experiments that Mr. Burbank has conducted for his own amusement, or for their scientific interest, with no thought of commercial results. All the clovers in this large bed bear four leaves, and they illustrate the possibility of fixing any given character by selection.
