Another Bed of Burbank Rhubarbs
Although the first Winter rhubarbs were developed by selection, Mr. Burbank subsequently used hybridizing experiments, with good results. He has experimented with a great variety of rhubarbs, and has found this plant a tractable and a peculiarly interesting pupil. Observe the prolific and compact growth of the specimen here exhibited.
