A. J. Hill, Collections of the Minnesota Historical Society for the Year 1867
“ Heat causes their flesh to shiver, and their teeth to chatter, while cold makes them perspire and pant. It is said of them, that in the coldest weather of the Minnesota winter, when mercury congeals, they seek some prominence on the prairie, where they put up some bushes to shelter them from the rays of the sun, under which they sit naked and fan themselves as they swelter with heat, and in the oppressive heat of summer they fold around them robe on robe, and lean over a rousing fire, sniveling and shaking with cold like one in a fit of the ague. ”
