In city parks they litter the asphalt walks, and drift along their edges into little heaps. They are bud-scales, whose day of usefulness is over.

Their horny substance has shed the cold rains of winter, resisted the frost, and protected the tips and shoots in which the life of the branches lay dormant. We owe to the bud-scales most of the beauty of the summer world. Their highest usefulness has been attained through sacrifice of thei...
