learned to collect honey from objects other than flowers, will 

 visit such objects as soon as they are attached to the support 

 (Ex. 8, 19), at times they will even enter them while they are 

 being attached to the support (Ex. 28), or they may even enter 

 such an object while held in the hand (Ex. 31, 32). 



If a set of bees has become accustomed to collect honey 

 from artifacts, and paper discs, arranged in pairs of one red 

 and one blue (or discs of any other two colors) are scattered on 

 weeds or placed on weed-high rods, and honey is placed on the 

 discs of one color and none placed on those of the other color, 

 the bees will make regular visits to the color that bears the honey, 

 but will not so respond to the other color (Ex. 8, 9, 10, u). If 

 these experiments are repeated, using cornucopias (Ex. 19) or 

 boxes with small openings (Ex. 29) in place of the discs, the 

 results will be the same. If bees have become accustomed to col- 

 lect honey from an artifact of a certain color, and empty artifacts 

 of the same kind and color are placed along side of those that 

 contain honey, many of the bees will enter those artifacts that 

 never have contained honey; empty artifacts of a different color 

 are not responded to in that manner (Ex. 23, 24, 28, 29). After 

 bees have, for a long time, been collecting honey from artifacts 

 of a certain color, if all the artifacts be removed from the field 

 except two that never have contained honey, but one of which 

 is the color of the artifacts from which the bees have been col- 

 lecting honey, numerous bees will flock into the empty artifact 

 of the same color as those from which the bees have been foraging; 

 but none, or nearly none, will visit the other artifact (Ex. 25, 30). 

 When bees have become accustomed to collecting honey from other 

 sources than flowers, if receptacles of two different colors are 

 placed on a bush, all of one color containing honey and all of 

 the other color being empty, and if, after the bees have been busy 

 for a long time, honey is placed in one of the artifacts of the color 

 that has been empty all along, it will remain on the bush some 

 time before it will be visited by any bees (Ex. 12, 13, 21, 22). 

 All of the facts recorded in this paragraph indicate that the be- 

 havior of foraging bees is influenced by colors. 



That these bees not only respond to colors, but that they are 

 capable of recognizing them at a distance is evidenced by the
