Once upon a time there lived a baron on the estate of Vana-Vigala. People said he used to have ghosts in his service. Once, going to Tallinn, the baron drove straight across Lake Ülemiste. Turning onto the lake he wanted the coachman not to look back.
The carriage rolled on the surface of the water like on the smoothest highway. When it was already near the other shore and there was no more fear of drowning, the coachman did look back. Great was his wonder when he saw an army of ghosts, all taking boards and planks from behind the carriage and building a bridge of them in front.
As soon as the coachman had set his eyes on the ghosts the carriage sank into the water together with the horses, but as they were so near the shore the horses swam out and saved them from drowning.
Later, the baron told the coachman, “If you had looked back in the middle of the lake we would have drowned. The ghosts don’t work if a human eye can see them. Don’t you ever go against my orders again!”
