The high percentage ot failure and low num- ber per pod in the last period are caused in part by failure to mature early enough. The percentage of failures in the above table is very much higher than need be the case where regular daily attention could be given. Crosses have frequently had to be made when pistils or pollen were not in the best condition; it has seldom been possible to follow up and poUenize a second time those which looked doubtful, and it has often been necessary to operate on days when the weather has not been favorable. There is no point in the whole opera- tion of more importance than that of working on a bright, sunny day, and after the sun has been shining for some hours. When the pollen is like dry dust, and scatters at a touch, the conditions are best. When the pollen is gummy and has a tendency to cohere at all, failure is almost certain. Some varieties produce two kinds of anthers, one set longer and with smaller anthers maturing first. The pollen from these stamens is frequently impotent, while the second set, with shorter fila- ments and larger anthers, produces later a pollen which is strongly potent. The condition of receptiveness of the pistil varies largely with the variety. Some varieties like Enchantress are r
