 field of well-developed cotton plants may readily adver- 

 tise its location to the olfactory sense of bees by odorif-

 every air-movement. During a hot, sunny afternoon the 

 combined odors volatilizing from the great numbers of 

 foliage and floral nectaries, the pollen, etc., must be very 

 considerable. Especially during clear sunny days fol- 

 lowing periods of cloudy or rainy weather bees become 

 unusually active and numerous. Many of these visitors 

 have no doubt learned the location of the fields by previ- 

 ous association.
