OAK FAMILY tire subject of spring and autumn tints is becoming more and more interesting as it is more carefully studied. It is now well understood that the frost is not a factor in the problem and that both spring and autumn tints arise from changes in the character of the chlorophyll ; the one when the chloro- phyll is not yet mature and the other when it is dying.
