'THE launching of a new liner for gret company like the Cunard, especially when it marks wuch new departure on the part of builders and owners as the intro-; duction of turbin—driven machi- 4 nery, ix x matter of interest in any shipping community and we make no excuse therefore for referring at greater length to the pamphlet recently sent us by Mr. H. P. King as local agent of M sers, John Brown & Ca., Ld.. of Clydebank, descriptive of the latest Cunarder, the Carmania, now satisfuetorily established on the run across the Atlantic. A glance at the illustration showing the complete vessel steaming at 20} knots impresses one with her beautiful appearance and sym-irienl proportions, and the following particulars of her dimensions, accommodation, and machinery will give a good idea of the very liberal scale on which she has been planned. Length between perpendiculars, 650 ft length over all, 672 ft. 6 breadth, moulded, 72 ft.; depth, moulded, 52 ft.; depth from keel to roof of navigating bridge,,90 ft. feom keel to top of funnels, 144 from keel to top of masts, 205 {t.; gross registered tonnage, 19,524 tons; collective length of decks, 3,900 fe. Thereis accommodation for nu fewer than 2,626 passengers (first-class 300, second 326, and third and steerage 1,000 each) whilst the officers, engineers, ind crew number 710 thus making a tota! of 3,336 persons. The cargo cap city of the vessel is 10,000 tons; the draught in working condition 33 ft. 3} nnd th" displacement at thi draught 30,918 tons, Her muchinery consists of tripl-screw turbines for steaming ahead, two turbines for teaming "-tern, de signal horse-power 21,000 indicated hursepower, a d eight double-ended and five boilers, The heating surf we per ind ested horse-ris 2.85 square feet and tie iwliewed how-power per square foo: of urite 17.3. She has " speed of 20.5 knots, In this ship we have practically the highest development of the turbine system, not only in respect of the carefully evolved details of design, but also of the sze of the machinery, the hip beng the fastest steamer of her grent. dimen-ions now afloat. ~The punphlet gives some very interesting details of the trial runs of the grent vrasel, which occupied practically only one work from the time the ye-sel I: ft. the Clydebank Works, the performance of the ship being exceptionally favourable from beginning to end, The steaming tate excited very considerable nttention among marine constructors, nnd were attended by representatives of several important interests, Bath the Ra-sian and Japanese navies also had their representatives. The day after the armenia lof. the rik Work: trial, and as this proved nite satisfactory it was decided to run the first of the official trials, This trial consisted of four runs over the measured mile at full speed, the vessel subsequently continuing, at the mean revolutions developed on the measured mile, to complete a coninuons steaming trial of six hours 4 ctunl speed maintained on this occasion was 20.19 knots. The second official trial of six hours' duration took place about a month later. It had been decided on this occasion to run at between 19 and 20 knots, to represent the normal sca speed of the vessel. As over the whole courte a speed of 19.5 the conditions were more than maintained.
An interesting comparison is made between the turbine-driven Carman'a, and the sister-ship the the ordinary reciprocating machinery, which was also built at Clydebank, and as this latter vessel hay reached the high-water mark of economy both in coal and water consumption the Car-mania was judged by a very high standard, The result is that the Caronia, steaming under the same conditions as the Carmanis, had a speed of over one na per hour less than tha' vessel. This is attributable to the adoption of the turbine system; the efficiency of the propellers is evidently very satisfac ory, As regards the coal consumption, it. was not possible to take any data, Moreover, s: x hours was too short a period in' which to secure reliable information; but if one may judge by careful observation of the work done by the yokers in the two ships, then the mise is that the coal consump ion measured on the Ate lunatic will compare well with the very satisfac ry perlormauces 10 thig resp-ct of the Curonia. Under these circumstances we can well acquiesce: in the conclusion arrived at. that Messre, John Brown and Ca, La, are not only 10 b congra'ulatthe performance of th- Car-maniu, but, perhaps, even more on the judgment they have displayed in determining in favour of the adoption of this new system for Atluntic liners, and, in anticipation of developments, surrounding them-Selves with a stuff ut experts who have proved move then "qual tothe dommd that his been made upon them in connection with such great slop in the practical develop ment of the steam-turbine.
