Annual report ..[bulletins and circulars] . .—Catherine apricot ;injured pistil. Yet hardly a dozen Pollination in Orchards. 345. 76.—Catherine; injured pistil. flowers were even crossed by hand with the pollen of other varie-ties. Since the variety had already shown itself so susceptibleto winter injury, it is probable that this wholesale failure w^as dueto the weakened vitality of the pistils,which could not be seen with the eyealone. Some of the imperfect developmentof flowers which we attribute to win-ter injury may be caused by unfavor-able conditions during the previousseason, when the buds were beingformed; yet it seems likely that winterinjury to pistils is more common andmore serious than appears at first sight. These remarks onwinter injury are introduced simply to emphasize the fact thatall blossoms which do not set fruit are not self-sterile ; and alsoto promote a more careful discrimination between the variouscauses which decrease the setting of fruit. Rain may injiire fruit blossoms. The unfruitfulness which often follows a rain during theblooming season is sometimes confused with self-sterility.
