In the last days of autumn he had whitewashed the chalet, painted the doors, windows, and veranda, repaired the roof and interior, and improved the place so much that the landlord had warned him that the rent would be raised at the expiration of his twelvemonth's tenancy, remarking that a tenant could not reasonably expect to have a pretty, rain-tight dwelling-house for the same money as a hardly habitable ruin.
