Gilfillan on lodges
In 1873, nearly all the Ojibways everywhere, except for the few newly removed to White Earth, lived winter and summer in birch bark wigwams. Now, nearly all of them have built for themselves, or have had built for them by the United States Government, one-roomed log cabins, in which they winter; but in front of these, nearly every family puts up in summer in an old style birch-bark wigwam, in which they pass the summer, returning to the log house when the cold weather sets in. They properly prefer the wigwam for its greater coolness, better circulation of air and greater cleanness. There are still, however, some families who from preference winter in birch-bark wigwams.
