How Deep?
A discussion between
Sir Edward Bullard, F.R.s. and Maurice Hill, Ph.D. both of the Department of Geodesy and Geophysics
In the University of Cambridge
This week a group of scientists in Cambridge have been discussing how far it might be possible, with modern techniques, to drill into the earth's crust-50,000 feet is suggested. Their interest in such a project is that drilling might provide experimental evidence of changes in the earth's interior that at present can only be deduced from ' seismic shooting' and the study of earthquakes.
