Two investigators, Sladen of England and Casteel of this 

 country,, have contributed articles on the behavior of the honey 

 bee in pollen collecting. F. W. L. Sladen (87) says that the 

 pollen is gathered directly upon the metatarsal brushes. By 

 sci aping the inner sides of the metatarsi the pollen is compacted 

 in the corbiculae. In spite of Cheshire's statement to the con- 

 trary,* Sladen asserts that theie is no crossing ot the legs. 



At the beginning of his article, Casteel (15) emphasizes the 

 well-known fact that bees do not combine pollen collecting with 

 honey gathering. Following that statement comes a detailed 

 account of how pollen is collected. In moving about among 

 the stamens, some pollen clings to the hairs of the body and of 

 the legs; but the greater part of the pollen is collected by the 

 mandibles and tongue. The pollen collected by the haiis of the 

 body and of the legs is dry; that collected by the mouth-parts 

 is moistened with honey supplied by the mouth. The first pair 

 of legs collects the dry pollen from the head region and the 

 moist pollen from the mouth-parts. The second pair of legs 

 removes the pollen from the ventral side of the thorax and 

 receives that w-hich has been collected by the fiist leg. The 

 third pair of legs collects the pollen from the abdomen and 

 receives that which has been collected by the second pair of 

 legs. The third pair of legs now scrape the pollen from the 

 the combs and sides of one into the corbiculae of the other. 

 The moistuie which has been supplied by the mouth causes it 

 to adhere. In unloading the bee grasps one edge of the cell 

 with her forelegs and arches her abdomen until its posterior 

 edge rests on the opposite side of the cell. The middle legs then 

 shove the pollen mass fiom the third legs into the cell. Usually 

 another bee enters the cell, breaks the pellets with her mandibles 

 and tamps down the mass in the bottom of the cell. She prob- 

 ably adds more fluid. 



C. H. Turner (98) found some orphan Polistes pallipes., that 

 he had raised from the larval stage, so tame that they would 

 accept honey or insect larvae when offeied to them on glass
