Mr. Burbank and Dr. Hugo de Vries
This picture was taken in Mr. Burbank's garden, on one of the occasions when the famous Amsterdam botanist visited Santa Rosa. Dr. de Vries has written several highly appreciative articles concerning Mr. Burbank's work; and a large part of one of his recent volumes on plant breeding is devoted to the work of the Santa Rosa experimenter.
