Oberlin, Ohio.
MEETING OF THE BIOLOGICAL CLUB.
The Biological Club met in the Zoological lecture room on the evening of October 7th, at seven o’clock. Professor Osborn presided over the meeting.
The minutes of the June meeting were read and approved. The evening was given to reports on personal work and observations of the summer.
Professor Prosser reported that he had spent part of the summer in northern Ohio. He visited points along the Cuyahoga and Rocky rivers, and studied the outcrops of the conglomerate at Boston Ledges, Little Mountain, Thompson Ledges, Nelson Ledges and at Sharon in Pennsylvania.
Professor Kellerman collected a quantity of material in the Gauley Mountains of West Virginia, adding a number of plants to the published list of that state and securing a few that appear to be new to science. He also collected several hybrid oaks in Ohio, and some specimens of Cratægus, which Dr. Sargent of the Arnold Arboretum pronounces new species. A number of species have been added to the published state list of Ohio.
Professor Mills gave a report of the opening of a prehistoric mound in Ross County just outside the town of Chillicothe. A number of skeletons and some very valuable material were obtained for the collections of the Ohio Archæological and Historical Society.
Professor Schaffner spent the summer in Kansas. He talked interestingly of a visit he made to the Pottawattamie Indian Reservation, and showed a series of photographs procured during a short stay among these interesting people. Scientific investigations were made on several subjects, among which the following may be mentioned: “The Self-pruning of Trees;” “The Distribution of Cacti and Ferns in Kansas;” “The Maximum Height of Plants;” and “The Timber Conditions of Kansas.”
Professor Landacre gave observations on the cocoon-spinning and egg-laying of the common garden spider.
