RAGWEED. A common weed in waste places. Many people suppose its pollen an effective cause of hay fever, and find relief on the Island owing to the supposed absence of this plant. This relief however, it seems, must be attributed to some other cause, as the plant in question grows everywhere,—even on the Cranberry Isles,—in more or less abundance, and is spreading with the increasing settlement of the Island. RUDBECKIA, L. CONE FLOWER. 291 R. hirta, L. YELLOW DAISY. BLACK-EYED SUSAN. Naturalized in grass fields from the West. Very common about Somesville and Bar Harbor, and more or less abundant all over the Island. A fastigiate form, Seal Harbor (Redfield).
