greatest interest. The collecting is after a manner novel to the 

 ^'land lubber." The collections, carried back to the Laboratory for 

 study, have the fascination of the unusual, for represented among 

 them are families more or less unfamiliar to general students. 



A collecting trip for water-plants usually takes one across tlie 

 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 througli 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 col- 

 lecting 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 neigh- 

 bors. 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 com- 

 mon 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 tlian of work— was but a suggestion of what might 

 be done, though one which proved quite powerful. From our land- 

 ing 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 

 Tv^ere never disappointed. 



DRAGONFLTES OF SANDUSKY. 

 James S. Hine. 



As the dragonflies of Sandusky have been quite carefully col- 

 lected 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 aniericana have not been 

 taken as commonly as in some places, for the locality does not 

 iurnish their most desirable surroundings.
