In a recent number of the Monthly you say with a doubt, that you encountered the famous potato bug on the plains of Colorado in 71. In 73 I saw a stalk of Solanum rostratum in a new street on the outskirts of Denver, covered with them, and saw them also on the same plant at a railroad station of the Kansas Pacific, between Salina and Denver.

Is Campanula rotundifolia to be Hair-bell, or Hare bell ? The Origin of the name should determine that. I see no connexion between the flower and the hare. The plant grows on steep, rocky cliffs, which hares do not frequent. Nor do I see any connexion between the flower and hair, except the remote supposition that it might have been so called because used by ladies to adorn their hair, or because the slender peduncles have a capillary look. My own conjecture is that the name is a corruption of Air-Bell, confused through similarity of sound with the true Harebell, which is probably a Muscari. Looking up at them from the base of a cliff, as I have often done in my walks about Easton, the tiny bells of Campanula rotundifolia appear as if suspended in the air on invisible threads, and might well suggest the name. Why not adopt it and so write it?
