CHICKS HATCHED FROM ALCOHOLIZED EGGS 123 



Maze No. 1 



Maze No. 1 (which perhaps should not properly be called 

 a maze) was a straight path between two boards 55 cms. in 

 length. It stood on a table below which was the box in which 

 all the chicks were kept during the tests. One end of the path 

 was closed. The open end was even with the edge of the table 

 just above the box. During the tests of chicks 2, 6, 7, 9 and 34 

 the box was 79 cms. below the table edge. The wire netting 

 cover of the box was made to lean against the table in such a 

 way as to form an inclined plane from the table edge to the 

 box. The chicks showed such reluctance to leave the table 

 under these circumstances that the box was raised to within 

 six inches of the table and the inclined plane done away with. 



The chick to be tested was placed at the back of the maze 

 and the time it took to find its way back to the box recorded. 

 Each chick was given ten trials in succession. An interval of 

 one minute was allowed to elapse between the end of one trial 

 and the beginning of another. The chick was sometimes placed 

 in the maze by one experimenter and sometimes by another 

 to correct any initial direction error which might occur. 



The following table gives the results for Maze 1 :
