Dr. R.G. Arnold and Elwood Wohlberg setting up an experiment.

Bio/historical note: Elwood Wohlberg a University of Saskatchewan graduate student from Speers and Aberdeen area, sets up a rock analysis experiment at the Saskatchewan Research Council on the University of Saskatchewan campus. Powered rock was subjected to x-rays and the results were interpreted on a machine. The amounts of mineral in each sample could be determined. The Saskatchewan Research Council and the University's Department of Geological Sciences co-operated in the project and soon more graduates became involved. R.G. Arnold was head of the Department at this time.
