Egg Rock, a tiny island in Frenchman Bay. Because of the growing seasonal ferry traffic to Bar Harbor, Congress appropriated $15,000 for a light station on Egg Rock in June 1874. The lighthouse went into service on November 1, 1875. On March 25, 1876, a great gale flooded the dwelling and smashed its windows, moved the fog bell tower 30 feet, and swept away a fuel shed.
