Cell-making

Hive-Bee

| I will not here enter on minute details on this subject, but will merely give an outline of the conclusions at which I have arrived. He must be a dull man who can examine the exquisite structure of a comb, so beautifully adapted to its end, without enthusiastic admiration. We hear from mathematicians that bees have practically solved a recondite problem, and have made their cells of the proper shape to hold the greatest possible amount of honey, with the least possible consumption of precious wax in their construction. It has been remarked that a skilful
with fitting tools and measures, would find it very difficult to make cells of wax of the true form, though this is
effected by a crowd of bees working in a dark hive.
whatever instincts you please,
it seems at first quite inconceivable how they can make all the necessary angles and planes, or even perceive when they are correctly made. But the difficulty is not nearly so great as it
first appears: all this beautiful work can be shown, I think, to follow from a few
simple instincts.
