LABYRINTH HABITS OF THE PIGEON 



279 



DESCRIPTION OF APPARATUS AND GENERAL METHOD 



Labyrinth A (fig. i) is identical in plan with a labyrinth 

 designated as L by Rouse in his study of the pigeon.- It is 2 ft. 

 X 2h ft. X 7 in., inside measurements. The alleys are 6 in. wide. 

 The partitions of this maze are of wood, while those in the laby- 

 rinth used by Rouse were of wire. 



Labyrinth A, as well as the other boxes used in the present 

 experiments, is covered with \\ire.

Figure 2 — Labyrinth B. E, the entrance box; F, the food box; W, west: 1-7 

 indicate the bUnd alleys. 



Labyrinth B, (fig. 2), differs from A in the number and com- 

 plexity of its pathways. The results indicate that it approached 

 very near the maximum of complexity for the pigeon. Using 

 / to mean a turn to the left, r one to the right, and 5 a straight- 

 ahead, the arrangement of the blind alleys from entrance to 

 food-box may be indicated as follows : /, 5, r, s, I, r.
