forced draught. The f Tae Marine REVIEW PERUVIAN CRUISER CORONEL - BOLOGNESI. rial trip. of the cruiser Coronel Bolognesi, the second vessel of this type built for the Peruvian govern- ment, by Messrs., Vickers' Sons. & Maxim, of Barrow-in-Furness, affords some interesting details of the devel- opments of the scout class, or the eyes at the fleet" The cruiser has a length of 370 ft., a breadth of 40 ft. 6 in., and a draft of 14 ft..3 in., which 'will enable her to enter most of the harbors in South America. On this draft the displacement will be about 3,200 tons. The machinery consists of two sets of four-cylinder triple expan- : . ' ° sion engines, each set having four cranks balanced on the Yarrow-Schlick- Tweedy system. They are designed . to give a collective i.-h. p. of 14,000, 'with a steam pressure of 250 lbs. per square inch at the engines, and 280 Ibs. at the boilers. This will give a speed of 24 knots, and the coal en- durance at cruising speed will be about 4,500 'sea' miles, The ten boilers of the small tube type are arranged in three separate water-tight compart- ments, and at full power will work under the closed stokehold system of vessel has a complete equipment of auxiliary ma- chinery. The cruiser; notwithstand- ing the limitations in size and cost, is _ PERUVIAN CRUISER CORONEL BOLOGNESI effectively protected, as there extends a deck of 1%4 in. thickness for the full length of the vessel, so as to cover in, not only the magazines and steering gear, but also the boiler and machin- ery compartments. Extensive coal bunkers are arranged along the sides in the wake of the machinery space, so as to minimize penetration by shot and shell. 'The conning tower for- ward, from within which the ship will be controlled, and fought, is con- structed of nickel steel hardened ar- mour 3 in. thick. As regards the ar- mament, there is a 6 in. gun, with an armour shield on the forecastle deck forward and one on the upper deck aft. The service of ammunition and projectiles to these guns has had care- ful consideration in order to give them the maximum rapidity. Electric mo- tor ammunition hoists of the dredger type have been fitted, and these are protected by armoured tubes. The secondary armament consists of eight 14-pounder quick-firing guns, and eight 114 pounder guns, distributed principally on the broadside on the upper deck and bridges. There are two submerged tubes for firing r18-in. torpedoes. The cruiser has thus fea- tures which will commend her to such naval powers as Peru, where the ex- penditure of the navy is necessarily limited, as the vessel combines with exceptionally high speed of 24 knots.a considerable armament, including two weapons firing a 100-lb. shell at a ve- locity: effective against unarmoured craft at three miles range. While thus able to engage such craft, she will, with the assistance of the high speed, greatly harass armoured slower ships, and will at the same time, create those diversions which, when practiced even by relatively weak fleets, natur- ally influence the strategic plans of a superior force. The vessel has. also many qualities insuring the comfort of the officers and crew in the varia- ble climate of southern seas. She will have a total complement of 300 officers and men, and the living quar- ters are more comfortable than usual in, such; «small-craft. 'The' 'vessel is provided with refrigerating plant and ice-making machinery, with cold stor- age chambers adjoining, and _ the bakery is equipped with mechanical dough kneaders. Again the vessel is fitted with hammock berthing instead of rails, and the stowage of the ham- mocks within these adds to the pro- tection against machine gun fire, as was almost universally the case in ves- sels for the British navy a few years ago. There is fitted an installation of wireless _ telegraphy. The Coronel Bolognesi' carries two powerful searchlights, and nine small boats are carried' including a 34-ft. launch. steam
