Peach Buds (Magnified Twice). then sink several degrees below zero, there is scarcely a chance for their escape. Their condition may be soon ascer- tained by making a cross-cut with a knife through the fruit- buds. If destroyed, the centre will be dark brown; if unin- jured, they will present the fresh greenish centre of sound buds. The accompanying figures represent the branches and buds ot the peach magnified twice in diameter. Fig. 622 shows the two flower-buds, with the usual leaf-bud between, before they have become swollen by warm weather. Fig. 621 represents the appearance of the same after the occurrence of several warm days after midwinter. Fig. 623 exhibits the dark and dead interior of a flower-bud cut through its centre, after it has been killed by the frost. Under ordinary circumstances, the peach crop is destroyed when the thermometer sinks about 12° below zero (Fahr.); but when the buds have been much swollen, the crop has sometimes been cut off when only 5° or 6° below; while in rare instances unswoUen buds under. 30.
