t was one of those afternoons in late April which are as mild and balmy as any June day. The air was full of the chirps and twitters of nest-building birds, and of sweet indefinable odors from half-developed leaf-buds and cherry and pear blossoms. The wisterias overhead were thickly starred with pointed pearl-colored sacs, growing purpler with each hour, which would be flowers before long; the hedges were quickening into life, the long pensile willow-boughs and the honey-locusts hung in a mist of fine green against the sky, and delicious smells came with every puff of wind from the bed of white violets under the parlor windows.
