"The Phantom slowly, gravely, silently approached. When
it came, Scrooge bent down upon his knee; for in
the very air through which this Spirit moved it seemed
to scatter gloom and mystery.
It was shrouded in a deep black garment, which concealed
its head, its face, its form, and left nothing of it visible
save one outstretched hand. But for this it would have been
difficult to detach its figure from the night, and separate it
from the darkness by which it was surrounded.
He felt that it was tall and stately when it came beside
him, and that its mysterious presence filled him with a
solemn dread. He knew no more, for the Spirit neither
spoke nor moved.
'I am in the presence of the Ghost of Christmas Yet To
Come.' said Scrooge.
The Spirit answered not, but pointed onward with its hand.
'You are about to show me shadows of the things that
have not happened, but will happen in the time before us,'
Scrooge pursued. 'Is that so, Spirit.'
The upper portion of the garment was contracted for an
instant in its folds, as if the Spirit had inclined its
head. That was the only answer he received."
