At or about eleven o’clock on the morning of January 25th the United States battle-ship _Maine_ steamed through the narrow channel which gives entrance to the inner harbour of Havana, and came to anchor at Buoy No. 4, in obedience to orders from the captain of the port, in from five and one-half to six fathoms of water. She swung at her cables within five hundred yards of the arsenal, and about two hundred yards distant from the floating dock. Very shortly afterward the rapid-firing guns on her bow roared out a salute as the Spanish colours were run up to the mizzenmast-head, and this thunderous announcement of friendliness was first answered by Morro Castle, followed a few moments later by the Spanish cruiser _Alphonso XII._ and a German school-ship. The reverberations had hardly ceased before the captain of the port and an officer from the Spanish war-vessel, each in his gaily decked launch, came alongside the battle-ship in accordance with the rules of naval etiquette. Lieut. John J. Blandin, officer of the deck, received the visitors at the head of the gangway and escorted them to the captain’s cabin. A few moments later came an officer from the German ship, and the courtesies of welcoming the Americans were at an end. The _Maine_ was an armoured, twin-screw battle-ship of the second class, 318 feet in length, 57 feet in breadth, with a draught of 21 feet, 6 inches; of 6,648 tons displacement, with engines of 9,293 indicated horse-power, giving her a speed of 17.75 knots. She was built in the Brooklyn navy yard, according to act of Congress, August 3, 1886. Work on her was commenced October 11, 1888; she was launched November 18, 1890, and put into commission September 17, 1895. She was built after the designs of chief constructor T. D. Wilson. The delay in going into commission is said to have been due to the difficulty in getting satisfactory armour. The side armour was twelve inches thick; the two steel barbettes were each of the same thickness, and the walls of the turrets were eight inches thick. In her main battery were four 10-inch and six 6-inch breech-loading rifles; in the secondary battery seven 6-pounder and eight 1-pounder rapid-fire guns and four Gatlings. Her crew was made up of 370 men, and the following officers: Capt. C. D. Sigsbee, Lieut.-Commander R. Wainwright, Lieut. G. F. W. Holman, Lieut. J. Hood, Lieut. C. W. Jungen, Lieut. G. P. Blow, Lieut. F. W. Jenkins, Lieut. J. J. Blandin, Surgeon S. G. Heneberger, Paymaster C. M. Ray, Chief Engineer C. P. Howell, Chaplain J. P. Chidwick, Passed Assistant Engineer F. C. Bowers, Lieutenant of Marines A. Catlin, Assistant Engineer J. R. Morris, Assistant Engineer Darwin R. Merritt, Naval Cadet J. H. Holden, Naval Cadet W. T. Cluverius, Naval Cadet R. Bronson, Naval Cadet P. Washington, Naval Cadet A. Crenshaw, Naval Cadet J. T. Boyd, Boatswain F. E. Larkin, Gunner J. Hill, Carpenter J. Helm, Paymaster’s Clerk B. McCarthy. Why had the _Maine_ been sent to this port?
