It is perfectly amazing how much work is needed to drive the great error out of the world that hybrids are generally sterile, simply because that much abused beast, the mule, happens to be commonly (though not absolutely) sterile. Instances of the reverse are continually before us. One of the most useful is the success of Mr. Carman of the Rural New Yorker in getting a productive race of grain, between wheat and rye. He has also been very successful in getting the blackberry and raspberry to unite, though Mr. Wm, Saunders of London, Canada, has occupied this part of the field before him. Latterly Mr. Carman has been successfully crossing different species of roses, and has seedlings, but we do not yet know that the hybrids are fertile or sterile.
