Some ruined thane’s forsaken hall,
Explores the new domain and tries
Before the rest to view it all.
I think you have often noted the fact here related; when a family moves to a new house, it is the child, or the youngest daughter, who is the first to explore all the secrets of the new residence, and whose young eyes discover things which the older folks had not noticed.
Alone she lifts the latch, and glides,
Through many a sadly curtained room,
As daylight through the doorway slides
And struggles with the muffled gloom.
With mimicries of dance she wakes
The lordly gallery’s silent floor,
