In Sir William Logan and the Geological Survey of Canada, Dr. Robert Bell describes how the Survey's founder was often taken for a lunatic because of his peculiar appearance and odd behaviour. Once, when performing field work in the Gaspé Peninsula, Bell writes, "It was remarked 'he carries a hammer and pounds the rocks, like an idiot.'" The local authorities decided to send him to the Beauport Lunatic Asylum. "His long zigzag walks on the beach convinced them that he was not only hopelessly demented, but was rapidly getting worse, so while he was in the act of making one of his slants across the measures, he was seized by two men", Bell writes. Fortunately, Logan quickly explained his strange behaviour and was allowed to carry on with his work.
