E-Days preparations are under way Under the sponsorship of the An'derson-Carlisle Technical Society, Engineering Days will be conducted February 25 and 26, a Saturday and Sunday. The event, held on the Montana Tech campus, is scheduled from 1:00 P.M. to 10:00 P.M. on Saturday and from 1:00 P.M. to 9:00 P.M. on Sunday. Various departments on campus will arrange demonstrations with necessary visual aids and lecture material, portraying that department's role in training Montana Tech students, Re-sidents of Butte and neighboring communities are invited to attend to observe firsthand the type of education Montana Tech has to offer and the facilities available to aid that education. The initial planning was done by the following members of the Anderson-Carlisle Society: Don Rovig (adviser), Charles Donegan, Lew Gosnell, and Bob Seidel. Students have' been selected for committees for the departments with the duties of erecting the displays. Steve Bauer, junior in geophysics, uses signal generators and oscilloscopes to analyze the performance The chairman assigned to head these of a transitor amplifier. Displays like this will be a common sight all over campus on E-Days. committees are Jim Loomis for Engineering Science, Al Chiamulera for Metallurgy, Larry Wooden for Petroleum, Ray Hyppa for Mineral 'Dressing, Will Robinson for Mining, Pete Norbeck for Physics and Geophysics, Henry McClernan for Geology, Isaac Errett for the Department of Humanities, Bob Chew and Lee Staiger for the Physical Montana College of Min~ral Science and Technology Education Department, and Henry McClernan for the Sign Committee. rriday, February 17, 1967 During Engineering Days, the BUTTE, MONTANA Vol. XII, No.6 demonstrations of each department will be judged and a winner announced,

Pressure gauge is donated to Tech The Geophysical Research CorPoration of Tulsa, Oklahoma, a subSidiary of the Amerada Petroleum Company, recently donated an Arn-: erada Bottom Hole Pressure Gauge to the department of petroleum engineering. This gauge has a market value of $1,825,00. It is used in the petroleum production laboratory' to familiarize students with the ap-
Not-all E-Days exhibits will be large and complex. Small, effective displays like this, showing graduate student Abdel-Hamid Hussein using stereomicroscope', will be widely used.

"Mardi Gras" will be the theme of the annual Freshman Class dance tomorrow evening from 9 :00 to midnight in the SUB. The Innkeepers will play. Tech students will be admitted on their activity tickets. Others must pay SOc. Members of the decoration com, mittee are Noreen Alfredson, Fran Banfield, Connie Boston, Virginia McNelis, Carolyn Pes anti, and Kar~n Wedin. Doug Storer, Joan RobIns, Evalie Byrnes, Karen Novack, and Linda Griffiths make up the POster committee.
demonstrate the pressure gauge to the department, faculty and students. Dr. George Hetherington, who teaches in the petroleum production laboratory, plans to construct a shallow drill hole on campus and erect the appropriate equipment above the drill' hole to give the students a vivid demonstration of how the pressure gauge is operated from the surface. The case hole will he constructed so that pressures up to 2,000 p.s.i. may be obtained by an auxiliary pressure pump. Oil would be the fluid used in the well.

".Ns an era of unmatched progress generates new problems for society, man's demand for an environment tailored to his needs grows ever more intense. To meet this demand will require all of the engineering talent we can possibly mobilize. "Many of the tasks we face are those we ourselves have createdin our cities, in the air about us, in the water which sustains us. "Before the end of the century the engineer will combine with each segment of our national life to rebuild a new and far 'better urban America. And more than ever, the quality of his contribution will depend not only upon his technical abilities. It will be measured as well by his sensitivity to the people's needs. "Engineering ... for the Human Environment thus becomes more than a theme for National Engineers' Week in 1967. It is the very essence of the challenge that lies before us. I am confident that we shall prevail."
Students must file for scholarships before February 28 Members of the Scholarship Committee urge all qualified students to file scholarship applications for the coming academic year. Applications and- other informa~ion may be secured from the Registrars office and they must be filed on or before February 28. Upper-division students in degreegranting departments who are interested in specific scholarships designated for their departments should consult with their department heads before making application. To qualify for a freshman scholarship, the student must be accepted by the admissions committee and have made application for scholarship aid before February 28.

To make people more aware of tbe purpose of Engineering Days, the event has been scheduled this year to coincide with National Engineers' Week. Normally, the event is held late in Marcb. One facet of Engineering Days will be to point out the significant role played by an engineer as well as the education he must obtain. Along this line, the following words by President Lyndon B. Johnson seem especially appropriate.
$12,000 granted to continue asphalt prolect at Tech The Montana Highway Commission has recently awarded $12,000 to continue the Asphalt Adhesion Project at Montana Tech, originated in June 1966, under a grant' of $16,500, Dr. Keith Ensley, Associate Professor of Chemistry, is the principle investigator, while Hank Schulz is working as his assistant. The purpose of the project is to determine the aggregate that will bond best with asphalt and what possible treatments might improve the bonding. The r eseaech is based on the principle that energy is r e'leased when the aspbalt and aggregate are bonded (heat of imersion). Thus, the best bonding will produce the greatest increase of energy in the system. The heat produced in the bonding of different combinations .will be measured and compared to indicate relative bonding strengths, and the effects of various treatments' of the materials will also be measured. Briefly, two specially constructed thermocouple systems, equivalent to 400 thermocouples, are situated in a container to measure the heat produced in bonding. One set is main- tained at the temperature of the oven while the temperature of the other cell is increased slightly when
the bonding energy is released. When the two units are correctlv connected in series, the heat of the oven is cancelled out, leaving on lv the bonding heat. This heat produces a voltage in the thermocouples that is amplified and applied to a pen-recorder to produce a graph. Phase I, for which the initial funds were granted, involved the construction of a micro calorimeter, an instrument that mea sur e s J
changes of heat of millionths of a Calorie. Since very little heat was ~xpected from the bonding process, It was necessary to first construct the sensitive instrument. Also, during this stage, the remainder of the equipment with the experiment was set up. Phase II, for which the new funds have been provided, will be for the determination of )he various bonding strengths.
