“But what is it?” you ask. “Give me its formula.” I cannot. Yet you need it and will get it—something that cannot be had of the day, something that Matthew Arnold comes very near suggesting in his lines:—

The evening comes, the fields are still.

The tinkle of the thirsty rill,

Unheard all day, ascends again;

Deserted is the half-mown plain,

Silent the swaths! the ringing wain,

The mower’s cry, the dog’s alarms

All housed within the sleeping farms!

The business of the day is done,

The last-left haymaker is gone.
