Earthquakes, Weather Data Recorded On Seismograph
Bv JEANNE FITZGERALD
Earthquakes aren't the only disturbances recorded by the seismograph in the basement of Lindley hall.
Henry V. Beck, instructor in geology, said the seismogram will occasionally pick up atmospheric changes, especially heavy wind storms.
There are three seismometers in the small room. One picks up eastwest disturbances, another north-south disturbances, and the third vertical disturbances.
"To properly locate the earthquake, we need all three instruments," Mr. Beck said.
Each seismometer is connected by electric wiring to a galvanometer. The galvanometer contains a mirror which reflects a beam of light on a photographic recorder. When developed, the beam of light appears as a fine wavy line.
The three seismometers are set on a concrete pier which extends down to bed rock under the building. The particular rock which the pier rests on is Lawrence shale.
Each seismometer consists of a magnet and a pendulum. When an earthquake hits the pier, the magnet moves with reference to the pendulum and sets up an electric current which is carried to a galvanometer.
This causes the mirror in the galvanometer to move and deflect the beam of light which shines on the photographic recorder. Each disturbance will cause a larger wave to appear on the record.
With each earthquake, there are two sets of waves which travel through the earth. These are the primary and secondary waves. Long waves, which travel parallel to the earth's surface, come in last. When they die out the quake ends.
There is a large clock in the room with the seismograph which, Mr. Beck explained, "is rigged up with relays which cause a deflection of the beam of light reflected from the galvanometers."
These deflections appear as time marks on the record. There is a timeapse of one minute between short marks and one hour between long marks. Each record shows a 24-hour period. They are changed daily at 1 p.m. When a disturbance occurs, it is reported to Washington, D. C.
Lutheran Students To Attend Conference In Nebraska
A delegation from the KU Lutheran Student association will leave today for Dana college, Blair, Neb. to attend the Fall Planning conference for the Midwest region.
Those who will attend the conference include: Margaret Allison, local president; Richard Pries, counselor; Darlene DeMertit, education junior; Susan Baird, College freshman; Eugene Brubaker, education junior; William Spomer, College sophomore; Gaylord Benton, business senior; and George Hotz, engineering freshman.
eckron, Doyle Appointed
SA Social Co-Chairmen
E. Lynette Leckron, College freshman, and William Doyle, fine arts sophomore, have been appointed social co-chairmen of the Independent Students Association.
The ISA will sponsor the sale of Christmas cards in the Union Thursday through Saturday, Nov. 15 through Nov. 17, and Monday, Nov. 19.

Short-wave radio in the room receives a time signal from the Naval Observatory time station, Washington, D.C., at 6 p.m. This time signal can be sent through the galvanometers to make a deviation on the records just as the clock does. This is a check on accurate time.
The room containing the instruments is lighted by a red light to make it photographically safe, Mr. Beck explained.
"If the photographic recorders were exposed to any other light, they would be ruined. There is also an alarm system consisting of a photo-electric cell hooked onto the east-west component which sets off an alarm in my office if the disturbance is very great." Mr. Beck said.
From the hallway outside the room, persons may watch the instruments through two observation windows. A display case in the hall contains some of the recordings made with the seismograph and a description of the instrument.
Credit Executives To Meet Saturday
Officers and executive committee members of the associated credit bureaus of the Mid-West will meet at the University Saturday to plan their 1952 institute.
A course of study and faculty for the institute will be arranged. The 14 executives meeting here were elected at the annual credit bureau and collection service management institute held on the KU campus the past summer.
The associated credit bureau of the Mid-West is represented by five states—Arkansas, Colorado, Kansas, Missouri, and Oklahoma.
Library Appoints Circulation Clerk
Mrs. Merrill D. Athon has been hired to work on the circulation desk at Watson library.
She will take over part of the duties assigned to William R. Holman, supervisor of the stacks, who resigned last week to become librarian at Edinburgh Junior college, Edinburg, Texas.
Mrs. Athon, a graduate of Emperor State Teachers college, has formerly been employed in the public library in Kansas City, Mo., and as assistant librarian at Park college, Parkville, Mo.
Dr. John C. Frye, executive director of the State Geological Survey, and Robert Kulstad, geologist with the geological survey, will attend the 64th annual meeting of the Geological Society of America in Detroit this week.
Two To Attend Geology Meeting
Dr. Frye, as a sectional meeting co-chairman with A. N. Sayre, chief of the ground-water branch of the Federal Geological Survey, will be in charge of the session on geomorphology and glacial geology.
Before the meeting he will go on a two-day pre-meeting field trip, arranged for the study of glacial features in southern Michigan. Also while in Detroit he will attend, as a member, a meeting of the American Commission on Stratigraphic Nomenclature.
Appearing in the GSA printed program is an abstract of a paper by A. R. Leonard, a Lawrence man with the Federal Geological Survey, and Dr. Frye.
The paper, "Problems of Alluvial-Terrace Mapping for the Engineering Geologist," mentions that terfaces are important in that cities and transportation are built on them and in that they are a source of construction materials and contain large supplies of ground water.
The paper explains that the engineering geologist, who is concerned with the materials underlying the surfaces, must be able to reconstruct the physiographic history of the valley in which the terraces occur.
3 New Committees Set Up For Ball
Three more committees have been set up for the Military Ball to be held Friday, Dec. 7.
Chairmen of the committees, selected at the second meeting of the Military Ball steering committee, are Bob Springer, Air Force ROTC, invitations; Kenneth Merrill, Navy ROTC, traffic control and security, and Stephen Tkach_ Army ROTC, refreshments.
A plan for sending invitations also was devised. Every cadet will turn in the name of his date and the organized house in which she lives. The committee then will deliver the invitations to the cadets' dates. Deadline for turning in names of dates is Friday, Nov. 30.
Cadets with dates living outside organized houses will pick up invitations from their respective ROTC office.
Tin cans are not tin at all, but sheet steel coated with a thin film of tin. This coating is only about $ \mathrm{1 \frac{1}{2}} $ per cent of the total weight of the can.

Eight To Debate At K-State
Four debate teams from the University will participate in a tournament for beginning college debaters at Kansas State college Saturday.
"At least 22 teams from Nebraska, Missouri, Oklahoma and Kansas will be entered in the tournament," said Cam Conboy, instructor in speech said.
K. U. debaters competing will be: William Arnold, Frederick Rice, Lee Baird, Robert Kennedy, Jerry Jacobson, John Wyman, Hubert Bell, and George Stoepewelwert. The teams will participate in four rounds of debates.
Former Student Killed
Cpl. Robert E. Bigelow, student at the University from 1939 to 1941, was killed in the Korean war. He was the son of Mr. and Mr. Alberts S. Bigelow, Topeka.
New Business Class Set For Spring Term
A new course, Industrial Procurement, will be offered to juniors and seniors as an elective this spring by the School of Business.
John Cannon, assistant professor of economics, said two hours credit will be given for the course which will combine fundamentals of purchasing with business cases dealing with purchasing problems of industrial concerns.
Five hours of economics is required before students may enroll in the course. Paul McCollum, instructor in economics, will teach the course this spring.
