MEETING OF THE BIOLOGICAL CLUB. 
Orton Hall, Nov. 2, 1908. 
The minutes of the previous meeting were read and approved 
as read, after which the following, proposed at the last meeting, 
were elected to membership: B. M. Wells, Geo. Simmons, Clyde 
Miller, and John Foreman. 
The nominating committee submitted the following names 
for officers of the club during the coming year: 
President, Miss Freda Detmers; Vice President, H. H. Severin; 
Secretary-Treasurer, Arthur H. McCray. 
The persons named were unanimously elected. 
The program of the evening consisted of the president’s 
annual address by Dr. Geo. D Hubbard. 
The retiring president presented a preliminary report on the 
physiography of the four local quadrangles, covered by the Dub¬ 
lin, Westerville, East Columbus, and West Columbus topographic 
maps of the United States Geological Survey. He had done the 
work during the last year or more under the direction of the 
Geological Survey of Ohio, which organization is looking forward 
to the preparation of a bulletin discussing the geology, mineral 
and rock resources and physiography of this region. 
The area is about 27 miles east and west by about 35 north 
and south with Columbus near the center. At present, physio- 
graphically, it consists of a young till plain adorned with one 
large morainic belt in the northern part and several smaller 
moraines looped across it from east to west; with scattered 
kames and kame areas, and eskers; with kettle ponds and swamps 
usually now extinct; and the whole in a very youthful stage of 
dissection. 
The moraines were left by the halting retreat of the Late Wis¬ 
consin ice sheet, while the till plain is the aggregate accumulation 
of drift from two or more ice invasions. Many localities were 
mentioned where drift older than the surface material had been
