The Chilian navy has the two iron-armored, twin-screw, central-battery ships _Almirante Cochrane_ and _Blanco Encalada_, and the lightly armored turret-ship _Huascar_. The _Almirante Cochrane_ and _Blanco Encalada_ are 210 feet in length, 45 feet 9 inches in beam, 19 feet 8 inches in draught, and 3500 tons in displacement. The former carries four 9-inch and two 7-inch breech-loading Armstrong rifles, four lighter pieces, and seven machine guns. Before the alterations and repairs lately made, the _Blanco Encalada_ had six 12-ton muzzle-loading Armstrong rifles, four lighter pieces, and seven machine guns. The _Huascar_ was built in 1865, and is a slightly protected iron ship of 2032 tons displacement, 1050 horse-power, and 12 knots speed. Her battery consists of two 10-inch muzzle-loading Armstrongs and two 40-pounders. Her wonderful record on the west coast of South America has made her name as familiar in the mouth as a household word, and whatever may have been the justice of the war, there never can or will be a question of the superb courage with which she was fought by her gallant officers and crew. Chili has three wooden corvettes, the _Chacabuco_, _O’Higgins_, and _Pilcomayo_, one composite corvette, the _Magellanes_, one steel cruiser, the _Esmeralda_, five gun-boats, two paddle steamers, one despatch-boat, one transport, and eleven torpedo-boats. In April, 1885, the _Esmeralda_ ran from Valparaiso to Callao, 1292 miles, in one hundred and eight hours, the engines during the last eight hours barely turning over. In the exhaustive trials made before her departure from England the highest speed attained was 18¼ knots per hour. The _Esmeralda_ is said to be at present in an inefficient condition, both as regards her speed and battery power. In November, 1886, the Chilian government gave the Armstrong firm an order for a powerful, partially-protected steel cruiser, which is to be of 4500 tons displacement, and to develop 19 knots speed. Her armament is to consist of two 10-inch, one 8-inch, and two 6-inch Armstrong breech-loaders, with a secondary battery of four 6-pounder rapid-fire guns, eight Hotchkiss revolving cannons, and eight torpedo-tubes. The cost of this vessel is to be about $1,500,000. APPENDIX I. SUBMARINE WARFARE.
