along the lower or distal margin of the basket. (See fig 8, a.) It is 
in this position because it has been scraped from the planta of the 
opposite leg by the pecten comb and has been pushed upward past 
the entrance of the basket by the continued addition of more from 
below, propelled by the successive strokes of the auricle. Closer 
Fig. 8. — Camera drawings of the left hind legs of worker bees to show the manner in 
which pollen enters the basket, a, Shows a leg taken from a bee which is just begin- 
ning to collect. It had crawled over a few flowers and had flown in the air about five 
seconds at the time of capture. The pollen mass lies at the entrance of the basket, 
covering over the fine hairs which lie along this margin and the seven or eight short 
stiff spines which spring from the floor of the corbicula immediately above its lower 
edge. As yet the pollen has not come in contact with the one long hair which rises 
from the floor and arches over the entrance. The plauta is extended, thus lowering 
the auricle ; b, represents a sligbtly later stage, showing the increase of pollen. The 
planta is flexed, raising the auricle. The hairs which extend outward and upward from 
the lateral edge of the auricle press upon the lower and outer surface of the small 
pollen mass, retaining it and guiding it upward into the basket ; v, d, represent slightly 
later stages in the successive processes by which additional pollen enters the basket. 
(Original.) 
examination of the region between the pecten and the floor of the 
basket itself shows more pollen, which is on its way to join that 
already squeezed into the basket. 
If the collecting bee is watched for a few moments the increase will 
readily be noted and the fact will be established that the accumulat- 
ing mass is gradually working upward or proximally from the lower
