Copley Amory invited a group of about 30 scientists to be his guests at a conference at the mouth of the Matamak river in Canada where he had a summer house. The subject was various biological cycles, as it was known that different animals had huge variations in numbers over cycles of about 4 and 10 years. These various fluctuations were important to humans because they affected agriculture in many ways. Related matters of weather and climate cycles were also discussed and, surprisingly, the 11 year sunspot cycle did not dominate matters.
This report was filed by Ellsworth Huntington of Yale University working with an editorial committee and with the approval of the conference.
Some years later, Edward R Dewey, who had been studying economic cycles, was to find out about this conference and in a short space of time had contacted the organisers and the Foundation for the Study of Cycles was born.
