June Meeting.
The June meeting of the club was held in Zoological Lecture Room on the evening of the third.
The editor-in-chief of The Ohio Naturalist, Professor Schaffner, gave a financial statement for the year.
The Secretary read a communication from Professor Kellerman. This communication was concerned with the past and future of The Ohio Naturalist and an adjourned meeting was voted for its consideration. The following invitation was received from Professor W. D. Gibbs, Secretary of the Omega Chapter of the Society of Sigma Xi:
The Omega Chapter of the Society of Sigma Xi cordially invites the members of the Biological Club to be present at the final meeting of the Chapter, in the Physical Lecture Room, Saturday June 8th, at 11 o’clock a. m. to hear a lecture by Professor Charles F. Mabery on the subject: “The Petroleum Industry: Its Rapid Expansion and Future Promise.”
Dr. Bownocker delivered an instructive paper on “Oil and Gas in Southeastern Ohio.” The first oil well in that region was drilled about 1860 at Maxburg in Washington County. The wells in this region when first put down oftentimes yield 500 barrels or more daily but they soon decrease until the product of the same well may be only a few barrels each day. They are long-lived however and wells drilled in the Sixties are still producing. The oil in Southeastern Ohio has its origin in the various sands and therefore differs from that of Northwestern Ohio where all the oil is of limestone origin.
The speaker explained the nature of the country, especially in reference to the arches where practically all the oil is located.
H. S. Houghton not being present, Professor Landacre gave a short outline of the subject “A Study of the Muscular and Skeletal Structures in the Head of a 14 mm. Salamander.”
A. F. Conradi read a short paper on the subject “A Study of the Cecidomyidae and their effects upon Vegetation.”
