Abstract
Moravian missionaries recorded all births in two Eskimo communities in northern Labrador from 1778 to 1940. These records demonstrate an annual cycle in births characterized by a peak in March, a trough in June, with an amplitude of 80%; they agree with previous observations on seasonal breeding among the Eskimo made by early Arctic explorers.Entities:
