THE POLLEN SUPPLY. s^-^emur "When bees collect pollen from flowers they may )3e engaged in this occupation alone or ma^^ combine it with nectar gathering. From some flowers the bees take only nectar, from others only pollen; a third class of flowers furnishes an available supply of both of these substances. But even where both pollen and nectar are obtainable a bee maj'^ gather nectar and disregard the pollen. This is well illus- trated by the case of white clover. If bees are watched while Avorking upon clover flowers, the observer Avill soon perceive some which bear pol- len masses upon their hind legs, while others will continue to visit flower after flower, dipping into the blossoms and securing a plentiful supply of nectar, yet entirely neglecting the pollen. The supply of pollen which is available for the bees varies greatly among diflferent flow^- ers. Some furnish an abun- dant amount and present it to the bee in such a way that little difficulty is experienced in quickl}^ securing an ample load, while others furnish but little. When flowers are small and when the bee approaches them from above, little, if any, pollen is scattered over the bee's body, all that it acquires being first collected upon the mouth and neighboring parts. Very diflferent conditions are met with when bees visit such plants as corn and ragweed. The flowers of these plants are pendent and possess an abundant supply of pollen, which falls in showers over the bodies of the bees as thev craAvl beneath the blossoms.
