longitudinal red and green stripes contained honey; the others teere 

 empty. The lime consumed teas about fifteen minutes. 



Eleven t-nt ranees were made into the box marked with alternate 

 red and green longitudinal lines; no entrances were made into 

 any of the other boxe-. 



Exi'i KIMI:\T 18. The same kind and number of boxes teere used 

 as in the above experiment, hut they tee re arranged in the following 

 order: box marked teith alternate black and teliite longitudinal 

 stripes, box marked teith alternate red and green transverse stripes, 

 plain green box, box marked teith alternate red and green longitudinal 

 stripes, box mottled teith red and green, plain red box. Xone of the 

 boxes contained honey or ever had contained honey. The time con- 

 sumed teas about fifteen minutes. 



Thin v entrances were made into the box marked with alternate 

 nil and green longitudinal stripes, but no visits were made into 

 the interior of any other box. 



1 \IM KIMKXT if). An empty box marked teith alternate red and 

 green longitudinal stripes and teliich never had contained honey 

 teas placed on the palm of my hand and by its side teas placed an 

 empty box marked teith one of the other patterns. The entrances 

 of both boxes teere made to face the same teay. All other artifacts 

 teere removed from the field and my hand held near the stakes upon 

 tehich artifacts had rested. At the end of about tteo minutes the 

 position of the boxes teas altered. This maneuver teas repeated 

 teith each kind of box used in experiment eighteen. 



At least a hundred entrances were made into the box marked 

 with red and green longitudinal stripes; but not a bee entered 

 any of the other boxes. One bee acted a.s though it was going 

 io enter the box marked with alternate red and green transverse 

 stripes, but it did not do so. Towards the end of the experiment 

 t lie bees entered the box marked with alternate red and green 

 longitudinal stripes M> rapidly that it was almost impossible to 

 keep an accurate record. To one looking on, it seemed as ihoiigh 

 the bees were looking for something which they expected to find 

 in those boxe-. 



When I left for home the bees \\en- searching over and around 

 the barren stakes for something that \\.is not.
