 apple blossom, J. W. McColloch (Trans. Kans. State Hort. Soc., 32 (1912-13), 

 pp. 85-88, fig. 1). — ^The author presents a chart which shows the number of 

 different insects that visited apple blossoms at the Kansas Experiment Station, 

 with the comparative number of honeybees. During the course of observa- 

 tions made to determine the number of blossoms a honeybee would visit on a 

 trip, a bee which already carried some pollen on its legs was followed while it 

 visited 61 blossoms, and was then lost sight of in the top of the tree. Another 

 was watched while it visited 53 blossoms and several were followed while they 

 visited from 25 to 40 blossoms.
