Another View in Mr. Burbank's Gardens
This picture gives a very good idea of the way in which every inch of ground is utilized in Mr. Burbank's garden at Santa Rosa. Note, however, that the beds are sharply delimitated by board-borders, and that there is evidence of orderly arrangement, profusion of plants of many species, but quite without confusion.
