Much they saw, and far they went, and many homes they visited, but always with a happy end. The Spirit stood beside sick beds, and they were cheerful; on foreign lands, and they were close at home; by struggling men, and they were patient in their greater hope; by poverty, and it was rich. In almshouse, hospital, and jail, in misery's every refuge, where vain man in his little brief authority had not made fast the door, and barred the Spirit out, he left his blessing, and taught Scrooge his precepts.
