out of the cornucopias as though they \\vrr hunting for some- 

 thing. 



Exi'i-.KiMKNT 6. One of I lie cornucopias used in the last experi- 

 ment was replaced by an experiment box marked with alternate red 

 and green longitudinal stripes. The other cornucopia was left in 

 place and called striped cornucopia number one. Three groups of 

 three short stakes each were erected near the plant containing the 

 two stakes mentioned above. The Croups were about a foot apart 

 and the stakes in each group separated by an interval of about two 

 inches. The Croups iscrc numbered from two to four, two being tin- 

 nearest to the two stakes and four being the most remote. The stakes 

 were arranged in a section of a curve. On the top of one of the stakes 

 in cadi group a cornucopia marked with alternate red and green 

 stripes was placed, while a similar plain red and plain green cor mi- 

 ned each of the other stakes. In no two groups was tin' 

 arrangement of the cornucopias the same. In the striped box and 

 in the striped cornucopias, honey was placed. The other artifacts 

 e empty. The position of the artifacts remained the same 

 throughout the experiment. 



This experiment began at about nine A.M . and extended until 

 noon. Except during the time consumed in taking a photograph, 

 the artifacts were watched continuously. Not a single visit was 

 made to either the red or the green cornucopias: but forty-seven 

 entrances were made into the cornucopias that were marked 

 with alternate red and green longitudinal stripes. These visits 

 were distributed as follows: striped box number one, nine; striped 

 cornucopia number one, twenty-one; striped cornucopia number 

 two, eight; striped cornucopia number three, seven; striped cornu- 

 copia number four, two. Tints all of the striped artifacts were 

 visited. Sometimes a bee would enter one artifact and then 

 leave and enter another and sometimes yel another. It usually 

 sipped honey in the last visited artifact only. In some cases the 

 cause of leaving tin- first artifact was the presence of sonic 

 bee; in most cases, however., I could not discover the cause for 

 departing. 



EXPERIMENT 7. .-1 fourth group of three stakes was added to tin- 

 above group and called group Jive: it was arranged about half way, 

 in a straight line, between croup two and group four. All of the
