_Wolf_ was equipped with a triple expansion engine and three boilers and one auxiliary donkey boiler. Her power plant was unique in that she could steam seven knots per hour on a consumption of eighteen tons of coal per diem, and eleven and a half knots per hour, her maximum, on twenty-eight tons of coal per diem. I have heard it said that she had one of the most efficient power plants out of Europe, having a fuel consumption of 1.2 per I.H.P. _Wolf_ was further equipped with a powerful searchlight, situated abaft the bridge, on a tower that could be raised or lowered at will. When not in use this light could not be seen above the top of the house. _Wolf_ sailed from Kiel on November 21, 1916. The Commander of the _Wolf_, Corvette Captain Nerger, of the Imperial German Navy, was a man of probably thirty-five years of age, of moderate height and slim build. He was immaculate in all things pertaining to his person, and was a strict disciplinarian. I was in Commander Nerger's quarters one day. I had visited him to thank him for the courtesy he had extended to my family and to myself, and found him a very agreeable man to talk to; a thorough gentleman and apparently anxious to do anything he could to make our lot bearable. In talking with him I found nothing to denote the arrogant Prussianism which is said to predominate in the higher branches of the German Navy. And yet Commander Nerger was a man "all alone." He kept absolutely to himself; took no man into his confidence. No man ever knew an hour ahead what his plans or the vessel's plans were. He was the only one who knew when we started for home. On the fifteen months' cruise of the _Wolf_ Nerger was in full charge and ran his vessel as a "one man ship." He lived in comfortable quarters on the boat deck, just under the bridge, and had his meals served in his private dining room. In the five months I was on the _Wolf_ I do not think I saw him on the berth deck more than a dozen times, and then only on an inspection trip of some kind. He always had the appearance of having just stepped out of a bandbox, he was so immaculate in his dress. I was told by his officers that Nerger never gets excited; always remains cool under all circumstances. They tell a story of his being in command of a light cruiser in the battle off the Dogger Banks, and throughout this engagement he calmly passed back and forth on the bridge, with a cigar in his mouth, giving his orders as calmly as if at some gun practice or manoeuvres. His officers and men all respected him, which to my mind is a good enough recommendation.
