From Extension Farm-News, January, 1950
Raymond Presnell, Watauga County farmer of the Shulls Mills community, is using electrically heated bee hives to winter over small colonies of bees.
Mr. Presnell believes that by wintering small colonies he can save considerable honey that strong colonies would consume.
W.A. Stephen says the electricity will enable the colonies to start brood-rearing and expanding their brood nests early next spring. Thus the small colonies should come through the winter and build up next spring equivalent to colonies going through the winter with much larger populations.
