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 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 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 than 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 
were never disappointed. 
DRAGONFLIES 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 americana have not been 
■taken as commonly as in some places, for the locality does not 
furnish their most desirable surroundings.
