Selecting two varieties before the flowershad opened, and before the anthers had burst and discharged•the pollen, he cut out with a fine pair of scissors all the sta-3xiens, leaving the pistils untouched (Fig. 17). When thestigma became sufficiently mature, which was indicated by itsglutinous surface, he transferred the pollen of the other sorton the point of a camels h
