A starboard side view, taken from just abaft the beam, of the steam tug Berwind (fl. 1930) in the entrance to San Juan Bay, Puerto Rico. Most of her hull and her stern are out of the picture. The photographer is on board a passenger cruise ship entering the bay and he is looking east over the tug to the west side of the Old Town of San Juan. El Morro Castle is on the left and the old Town is on the right, protected by the massive walls at the water's edge which has the San Juan Gate on the right, the only gate in the west facing wall.
