preached this box from the front alwav- entered immediately; 

 the majority of tlne that approached tin- sides pau-ed a nionu'iit , 

 then went to the nearest red box." This experiment indicated 

 that bees could di-criminatc between patterns. The purpose of 

 the researches to be described in thi.-. article was the establish- 

 ment of a definite experimental answer to that <]iieMion. 



The- method decided upon wa- to permit a few bees to learn 

 that honey could be collected easier from artifacts of a certain 

 color pattern than it could be from ordinary ilo\\ers; and, after 

 that had been thoroughly learned, to see if those bees could 

 select artifacts of that color-pattern from those of a different 

 color-pattern; 1st, when the artifacts to be Delected contained 

 honey and the others did not; 2d, when not only the artifacts 

 to be selected but some of the others also contained honey; .vl, 

 when none of the artifacts contained honey. 



The artifacts used were constructed out of cardboard and were 

 of three kiixU: circular discs about forty millimeters in diameter.

cornucopias made in the manner described on page 260 of tin- 

 article published last year, and special experiment boxes made 

 in the manner described on pages 271 and 272 of that article. 

 The artifacts used this year were smaller than those used last. 

 The cornucopias, excluding the lip, were fifty millimeters long 

 and thirty millimeters in diameter at the largest part. The 

 boxes, excluding the lip, were- sixty millimeters long, forty milli- 

 meters wide and twenty millimeters high. The pattern that 

 distinguished any artifact was placed upon both tin- inside and 

 the outside. The following colors and color patterns were used: 

 plain red, plain green, alternate red and green longitudinal stripe^, 

 alternate red and green tran-\erM- stripes, alternate black and
