A collecting trip for water-plants usually takes one across the Bay among the bulrushes and wild rice along Cedar Point. Here from the sides of the boat we look down into a wilderness of strange forms through the clear water. The curious eel-grass, with its perfect spirals, Myriophyllum and Chara, Philotria, Utricularia, and the Potamogetons spread out upon the surface among the lily-pads around us, are among the most conspicuous. A few minutes collecting here is productive of results quite out of proportion to the time spent. Many of these plants, at the time of my visit, had lifted themselves to the surface and bore their inflorescence above the water. Among these were some of the Potamogetons, Utricularia, Philotria, and others. A marigold looked strangely out of place on the surface of the water—it was the Bidens Beckii in bloom. The American Lotus lifted its head conspicuously above its lesser neighbors. Some minute, light-colored, fluffy masses, floating far out in the Bay, we decided to be the pollen of the Vallisneria. I have said nothing of the Algae; the most of my work at the Laboratory, however, was with these forms. Many kinds are common and many more may be obtained by seeking for them. These types of plant life, in beauty of form and importance of study rivaled by none, repay much time spent upon them. The collecting and study of only a week here—a week, too, of recreation rather than of work—was but a suggestion of what might be done, though one which proved quite powerful. From our landing at Cedar Point was visible, for a long distance out, the bright pink of a Swamp Rose Mallow. It typified the week’s work, it was a suggestion, too, of other strangers which might be lurking behind those trees and among those vines and undergrowth. We found that the suggestion was not a vain one, and in following it out we were never disappointed. DRAGONFLIES OF SANDUSKY. JAMES S. HINE. As the dragonflies of Sandusky have been quite carefully collected for a number of years, it may be worth while to give the result in the form of a list with notes on some of the species. Calopteryx maculata and Hetaerina americana have not been taken as commonly as in some places, for the locality does not furnish their most desirable surroundings. The genus Lestes is represented by unguiculatus, uncatus, disjunctus, forcipatus, rectaugularis, vigilax, inequalis and eurinus. Nearly all of these species are abundant and are mostly found among the grass at the edge of the marsh. The genus _Argia_ is represented by four species, putrida, violacea, sedula and apicalis. The first two are very numerous in individuals. Nehalennia posita and irene; Enallagma civile, ebrium, carunculatum, aspersum, exsulans, geminatum, antennatum, signatum pollutum; Amphiagrion saucium and Ischnura verticalis have all been taken, usually near the water’s edge.
