Excerpt from Heat Production of Honeybees in Winter In the colony of bees under observation in the respiration chamber the expenditure of energy was reduced to the lowest limit by the maintenance of favorable temperature and by the avoidance of all disturbing factors, so far as possible. Under these circumstances, rarely found in the apiary, the energy produced by the bees, as measured by the carbon dioxid and water produced and the oxygen consumed, was greater, according to body weight, than that pro duced by a man when working at hard manual labor, when we take into consideration the fact that the work was done by only a rela tively few of the bees in the cluster. Even assuming that the work of the period were equally divided among the bees, their energy output per unit of body weight is higher than that of the average laborer. when we take into consideration the fact that usually the bees do not have such favorable conditions in winter as these bees had, it is clear that the energy output is enormous in the average apiary.
