The liquid secreted in the nectaries of flowers is usually quite thin, containing, when just gathered, a large per centage of water. Bees suck or lap it up from such flowers as they can reach with their flexible, sucking tongue, 0.25 to 0.28 inch long. (Fig. 8, _l_.) This nectar is taken into the honey sac (Plate II, _h.s._) located in the abdomen, for transportation to the hive. It is possible that part of the water is eliminated by the gatherers before they reach the hive. A Russian bee keeper, M. Nassanoff, while dissecting a worker, discovered between the fifth and sixth abdominal segments a small canal, to which he attributed an excretory function, and Zoubareff, having noticed bees ejecting a watery substance while returning from the fields, suggested that this gland probably served to separate a portion of the water from the nectar, the liquid deposited in the cells appearing to contain less of it than that just secreted by the flowers.
