This investigation was carried on under regular apiary conditions to study the variable factors entering into the outdoor wintering problem. During a severe winter strong colonies with heavy, medium, and light winter-packing and ample stores suffered a loss in their population in an invesre ratio to the degree of protection given them. Populous colonies slightly protected consumed per unit of population much less stores than weak colonies. Those having a minimum of stores, regardless of packing or population, failed to winter as well as those having ample stores.
