her eight curves, whenever they arrived 'at the experiment plot; 

 but the number of curves described were perceptibly fewer and 

 the lengths much shorter, and some of the bees seemed to fly 

 practically direct to tin- artifacts. 



On departing for home, all of the artifacts, except three striped 

 boxes, were removed. Those boxes were well supplied with 

 honey- 

 July nineteenth, I arrived at the field at 9:30 A.M. and found 

 the boxes empty and the bees living into and out of them as 

 though hunting for something. It began to rain soon after my 

 arrival, which made it impossible to continue my experiments 

 that day. On leaving, all of the artifacts were removed from 

 the field.

The morning was quite cloudy and when I arrived in the field, 

 at about half past seven, the bees were not foraging. 



EXPERIMENT 8. Three groups of three experiment hoxes each 

 were arranged in the manner described above. In each group there 

 was one box marked with alternate red and green longitudinal stripes, 

 one green box and one red box. The order of the boxes was different 

 in each group. When the experiment was about half over, the ar- 

 rangement of the boxes in each group was changed. All of the hoxes 

 marked with alternate red and green longitudinal stripes contained 

 honey; the others were empty. The experiment was an hour long. 



Twenty-five entrances were made into the interior of the striped 

 boxes; but not a single entrance into either the red or the green 

 boxes. The visits were distributed as follows: striped box num- 

 ber one, ten; striped box number two, eight ; striped box number 

 three, seven. Only once did a bee, on arriving at the plot, make 

 the irregular number eight curves mentioned above. < >n arriving 

 at the plot, the bee would either lly directly to one of the striped 

 boxes, or else fly along, examining box alter box, until it reached 

 a striped box. On leaving, the bees did not al\\a\s make flights 

 of orientation. Often a bee would arrive at tin- hind end of one 

 of the experiment boxes that contained honey and attempt to 

 find an entrance; then it would sidle around to the front end ,md 

 enter.
