When pollen is abundant, and the swarm is in prosperous condition, they soon reach the outside sheets of comb with the brood. At this period, when the hive is about full, and the queen is forced to the outside combs to find a place for her eggs, it is interesting to witness operations in a glass hive. I have seen her several times during one day, on the same piece of comb (next the glass). The light has no immediate effect on her "Highness," as she will quietly continue about her duty, not the least embarrassed by curious eyes at the window. Before depositing an egg, she enters the cell head first, probably to ascertain if it is in proper condition to receive it; as a cell part filled with bee-bread or honey is never used. If the area of combs is small, or the family is small, and cannot protect a large space with the necessary heat, she will often deposit two, and sometimes three, in one cell (the supernumeraries I suppose are removed by the workers). But under prosperous circumstances, with a hive of suitable size, &c., this emergency is avoided. OPERATION OF LAYING AND THE EGGS DESCRIBED. When a cell is in a condition to receive the egg, on withdrawing her head she immediately curves her abdomen, and inserts it a few seconds. After leaving it, an egg may be seen attached by one end to the bottom; about the sixteenth of an inch in length, slightly curved, very small, nearly uniform the whole length, abruptly rounded at the ends, semi-transparent, and covered with a very thin and extremely delicate coat, often breaking with the slightest touch. After the egg has been about three days in the cell, a small white worm may be seen coiled in the bottom, surrounded with a milky-like substance, which is its food, without doubt. How this food is prepared, is merely guess-work. The hypothesis of its being chiefly composed of pollen, I have no objection to; as it is sufficiently proved by the quantities that accumulate in hives that lose their queen, and rear no brood (that is, when a requisite number of workers are so left). The workers may be seen entering the cell every few minutes, probably, to supply this food.[6] [6] When the comb in our glass hive is new, and white, these operations can be seen more distinctly than when very old and dark.
