The portraits of algae given will suffice to indicate the wealth of material awaiting study and research at the Minnesota Seaside Station. The interior country with its forest and mountains is scarcely less interesting than the shore. The botanist from the East is particularly impressed with the magnificent size of the trees, the luxuriance of the Lomaria formation of the forest-floor and the wealth of epiphytic and parasitic vegetation.
