Where these grow most compactly, there are a few lesser plants intermixed, filling the niches, reaching into light above and spreading roots in the superficial layers of the soil. With permanent conditions, the mixture of plants will remain much the same year after year. They are nearly all perennials, holding their place by continuous occupancy of it. Each is striving to extend its domain, but there is little opportunity. In the permanent association of certain species together there are some fine mutual adjustments. The taller broad-leaved perennials, like swamp-milkweed and joe-pye-weed and boneset, root rather deeply, and stand stiffly erect. The top layers of the soil are left by them to such lesser things as marsh skullcap, bedstraws, and tear-thumbs, whose strag- gling sprays reach out and find the light. The annual herbs of the swale are few; they-are such as jewel-weed and Spanish needles, that depend for their opportunity. Flower and fruit of the jewel-.
