Book Description

Excerpt from The Homing of Ants: An Experimental Study of Ant Behavior The stage used consisted of a piece of white bristol board I 5 cm. Square; in the edges of two opposite sides perpendicular slits were made 2 cm. From each corner, for the purpose of attaching inclines to the stage. The center of this platform was attached, by means of a pin, to the cork of a bottle about 12 cm. High. Unless otherwise stated, a new stage was used for each series of experiments. All the inclines were made of the same bristol board as the stage and were about 3 cm. Wide and usually 30 cm. Long. For special purposes inclines were made by pasting two of these end to end. They were also modified in other ways. When an incline led from a stage downward, it was always attached so as to project 2 cm. Above the stage except when a dark chamber was used. When the incline led from the stage upward it was always attached so as to project 2 cm. Below the stage. The dark chamber con sisted of an inverted pasteboard box 8 x 4. X I cm. A flap about one centimeter wide and attached above was cut out of one end, and was pressed inwards to furnish a door through which the ants could enter the dark chamber. In order to observe what was happening on the under side of the stage and incline, a small mir ror, inclined at the proper angle, was placed on the island, at one side of the stage.
