(July 14, 7:30 ) Apparatus.—The cornucopias used in this series of experiments were made in the following manner: A piece of cardboard, colored on both sides, was cut the shape and dimensions shown in Fig. i. It was folded along the dotted lines and the flaps. FIG. i. fastened where they lapped. About one centimeter of the apex of the cone was bent over and fastened. When finished, each cornucopia was nine centimeters long, with an elliptical lip six centimeters wide and three centimeters high. The lip was used for attaching the cornucopia to some support. Incidentally it furnished a platform for the bees. Some of the cornucopias were red and some were green. EXPERIMENT 19.—In the weeds that were the seat of the experi- ments of yesterday, several cornucopias were arranged at dijlcroit.
