The wood cut represents tops of raspberry canes, the pith of which was bored into, and emptied out by the parent Bee. 1. Orifice which was closed with some kind of vegetable substance. 2. Egg* of Bee attached to Pollen. 3. Pollen, all of which, under the microscope, appeared to have the same form and color (yellow), evidently mixed with honey.
