Mounted in a five-foot tube in tail of Canso flying boat, a magnetometer scanner is examined by electronics operator before rake-off. From impulses recorded on a zig-zag graph, geologists can determine areas rich in minerals; motion picture camera simultaneously records ground from which impulses were received.

In the constant search to find and develop new mineral deposits lying beneath muskeg and rocky outcrops of the Canadian shield, prospecting has become a precise science. Replacing the grizzled sourdough's traditional shovel and canoe, the aerial magnetometer and scintillometer have become 20th Century tools of the modern geologist-prospector. Trailing the highly-sensitive, bomb-like magnetometer, this "flying lab" can criss-cross 500 square miles a day, while the signals emitted by the "bird" ferret out gold, nickel and uranium deposits lying deep beneath the forest floor.

Conference on day's findings is held in the field by engineer-geologists and flight crew of an aerial survey team. Push-button prospecting by air has advantage of speed and secrecy: a flying laboratory can survey a tract of land 10 miles by 50 miles before returning to its bush-land base.

Aerial prospecting is big business, calling into play the talents of geology, electronics and photographic experts. Here Nora Kiernan, employed by an aeromagnetic survey firm, checks over film from camera synchronized to record ground from which each signal of the magnetometer was received.

Bomb-like serial magnetometer, which measures local variations in earth's magnetic field, is checked by member of aerial survey team. Airborne prospectors from one major Canadian metals firm alone have already charted more than 40,000 square miles in surveys of Canada's potential ore resources.
