THE EVOLUTION OF THE BEE AND THE BEEHIVE
laid. This bee is common in America as well as in Great Britain.
Here we have a bee that has not developed the typical hairs of a honey-bee, that collects little or no pollen, that stores the cells in which eggs are laid with thin honey, which it brings straight from flowers and does not first deposit in honey cells—a bee that produces separate and distinct cells, which may or may not be in contact.

A little higher up in the scale of progress we find another group of bees, which burrow tunnels in sandy soil, some of them nearly a foot in length. The tunnels and the cells are lined with a paper-like material, and the cells are divided by partitions, which may or may not be in contact. These cells are furnished with a fluid mixture of pollen and honey, both of which have been swallowed by the mother bee. All this shows an advance over the work of the bee first described, inasmuch as pollen forms a conspicuous part of the food of the larvae and there is a common entrance through a tunnel to the cells (Fig. 11). The nourishing fluid is more liquid than that supplied by the higher bees, and the papery lining
